Botanical classification and source data for production

Updated scientific nomenclature

The genus Brodiaea , now frequently referred to as Triteleia according to the most recent and commonly accepted botanical classifications, belongs to the family Asparagaceae , more precisely to the subfamily Brodiaeoideae . It is important to note that this classification has undergone an evolution, and that these genera could once be found within the families Themidaceae or Liliaceae; however, the current trend is firmly oriented towards the Asparagaceae. This grouping in the Asparagaceae family also includes genera that you are familiar with, such as Leucojum, which facilitates technical consistency on our site and in your cultural practices.

The genus Triteleia includes about 14 to 16 distinct species, while the genus Brodiaea includes several, sometimes confusing with Triteleia or Dichelostemma. Commonly cultivated species include Brodiaea coronaria or Brodiaea elegans for the genus Brodiaea, and Triteleia hyacinthina or Triteleia laxa for the genus Triteleia. A popular horticultural variety on the professional market is Triteleia Queen Fabiola (often marketed as Brodiaea), a cultivar known for its intense blue-violet flowers.

Area of ​​origin and climatic characteristics

Brodiaea / Triteleia is primarily native to the west coasts of North America, covering areas extending from California and Oregon to southern British Columbia. A few species can be found slightly further south, towards northern Mexico, and very occasionally in other parts of the continent. Its natural habitat is characterized by temperate climates with a Mediterranean tendency , marked by mild, wet winters followed by hot, dry summers. The plant demonstrates excellent adaptation to summer drought periods.

In terms of altitude, the majority of species grow in plains or at low altitudes, generally between 0 and 1,500 meters. Although a few species, such as Triteleia hyacinthina, can be found locally higher, most prefer moderate relief such as hills, valleys or plateaus typical of their range.

Natural biotope and original soil requirements

The preferred biotope consists of open meadows , grassy heathland, clearings or edges of light woods, with a marked preference for well-drained soils, whether sandy-clay, silty-clay or even alkaline. Some species are particularly fond of areas that are temporarily wet in spring, such as vernal pools or seasonally flooded meadows that dry out completely in summer.

Soil depth and fine-element content play a crucial role in the survival of corms, protecting them from summer desiccation or excessive temperatures. Optimal exposure is full sun to partial shade ; dense shade is to be avoided.

Morphology and biological cycle of production

Structure and characteristics of the propagation corm

Brodiaea / Triteleia does not develop from a classic tunicate bulb like the Lily or the Tulip, nor from a tuber or a rhizome, but from a corm . The corm is a solid underground storage organ, composed mainly of parenchyma, wrapped in a thin fibrous tunic. It is often confused with a bulb because of its storage function but its structure is distinct.

For professional cultivation, commercial corms generally have a minimum circumference of 5+ cm . This corresponds approximately to a diameter varying from 1.5 to 2.5 cm for vigorous specimens ready for planting. The appearance of the corm is generally spherical or slightly flattened, often rounded at the base and pointing slightly towards the neck. Its outer envelope is thin, displaying a color that can vary from light brown to dark brown, sometimes with a slightly fibrous appearance.

The inner flesh of the corm, when cut, is firm, unsegmented, and white to light beige in color. These corms are physiologically adapted to relatively shallow planting in a light, well-drained substrate.

Leaf development and dormancy cycle

The foliage of Brodiaea / Triteleia, especially that of Triteleia laxa (formerly Brodiaea laxa), has important characteristics for professional crop management. This foliage is deciduous , meaning that it disappears completely at certain times of the year. It consists of narrow, green leaves, reminiscent of grass. These leaves emerge in spring, marking the beginning of the growing cycle.

From a technical point of view, the leaf cycle is relatively short: although the leaves appear in spring, they already begin to yellow and wither at the very moment flowering begins, typically in May. This early senescence is a crucial technical signal: it indicates that the plant is entering its summer dormancy phase, after flowering. The development of the first roots begins the previous autumn.

Summer is the complete dormant period for Triteleia laxa, during which the foliage is completely absent. This deciduous nature is a morphological and physiological adaptation to the plant's native climatic conditions, allowing it to survive periods of summer drought by entering underground dormancy. The plant's ability to adapt to various soil types, from sandy to fairly clayey and even somewhat heavy soils, provided they are well-drained, also influences the development of this foliage.

Floral characteristics and commercial potential

The flowers of Brodiaea / Triteleia offer precise technical characteristics, essential for professionals aiming for production in France. They are grouped in terminal clusters called inflorescences, which can be umbels or cymes . Each inflorescence is composed of multiple flowers, generally bell-shaped or trumpet-shaped, typically described as campanulate, and sometimes slightly star-shaped depending on the variety.

The size of the individual flower is modest, usually measuring 2 to 3 cm in diameter . The flower stem that carries this cluster is robust and reaches a height of about 40 to 60 cm, or even up to 60 cm for some species or varieties such as Triteleia laxa. The dominant colors vary considerably depending on the species or cultivar grown, ranging from a deep blue to various shades of purple, mauve, white, and sometimes pink.

For example, 'Queen Fabiola' is famous for its deep purplish-blue, while Triteleia hyacinthina is distinguished by its white flowers. The flowers can be solid in color or have slight mottling. Olfactory-wise, Brodiaea / Triteleia are not generally known for their fragrance; it is most often absent or very weak, which differentiates them from many other bulbs.

Dimensions and vegetative port

Brodiaea / Triteleia has a mature height that varies depending on the species and cultivar, offering a range suitable for various professional uses, including landscaping and cut flowers. The average mature plant height is generally between 25 and 70 cm , with a common average of around 35-40 cm for most varieties.

These bulbous plants are characterized by a predominantly erect habit , meaning that their flower stems stand straight above the foliage. The leaves, which emerge directly from the stump, are linear and measure between 5 and 15 cm long.

Some specific varieties have distinct heights: for example, Brodiaea 'Koningin Fabiola' (Queen Fabiola) reaches about 30 cm in height with a spread of 10 cm, while Triteleia laxa is around 35 cm. The cultivar Triteleia laxa 'Queen Fabiola' is also given as 35 cm, Triteleia Rudy as 40 cm, Triteleia Silver Queen as 45 cm, and Triteleia Corrina as 25 cm. Triteleia Aquarius and Triteleia ixioides Starlight reach 40 cm and 30 cm respectively.

Production and multiplication techniques

Priority vegetative propagation methods

The propagation of Brodiaea / Triteleia is a fundamental technical aspect for professional production. The most efficient and commonly used method of propagation, especially in a commercial setting, is vegetative propagation by corms . This involves the division of mother corms that produce daughter corms, or cormels, during their growth cycle. This method ensures faithful reproduction of varietal characteristics and a production speed adapted to market needs.

In cultivation, each corm can generate between 1 and 3 new corms or cormels per year . These cormels will generally require 1 to 2 additional growing cycles to reach a sufficient size to flower and be marketed, depending on the cultural conditions applied.

Propagation by seed is also possible, but it is much slower. From seed, it takes on average 2 to 3 years to obtain a plant capable of flowering, or even longer if conditions are not optimal. Sowing is carried out at a shallow depth (0.5 to 1 cm), and although the seedlings emerge easily, the production rate by this method is less rapid for commercial exploitation.

Optimized planting calendar and techniques

For professionals in France, successful establishment of Brodiaea / Triteleia depends on following a precise planting schedule and appropriate techniques. The ideal time for planting corms is in spring, generally between March and April , when soil temperatures begin to rise. A minimum soil temperature of at least 10°C is recommended to ensure good corm recovery; planting below this threshold may compromise success.

In temperate climates with mild winters, autumn planting is also possible, typically in October. However, in colder areas of France, it is best to wait until spring to avoid the corms being exposed to severe winter frosts or prolonged cold humidity, which can lead to rot.

When it comes to technical aspects, planting depth is crucial: corms should be buried between 8 and 10 cm deep . The recommended spacing between each corm is approximately 10 cm . To achieve optimal professional density and ensure a dense visual effect in a clump or uniform production, aim for approximately 20 corms per square meter with this spacing.

Water and nutritional management adapted to the cycle

Water and fertilization management for Brodiaea / Triteleia must be adjusted to the specific vegetative cycle of the plant for successful professional production. During the active growth period, which extends from early spring until the end of flowering, the soil should be kept moderately moist , without ever being waterlogged. Depending on soil texture and climatic conditions, a water supply of about 20 to 30 mm per week is usually sufficient.

It is best to use watering systems that target the base of the plants, such as sprinklers or drip irrigation, to avoid excessive moisture on the foliage, which could encourage disease development. However, once the foliage begins to yellow and the plant enters its summer dormancy, it is imperative to gradually reduce and then stop watering completely . The soil must remain dry throughout the dormant period to prevent bulb rot, their main threat during the dormant period.

Regarding fertilization, an initial application is recommended before planting, in autumn or at the end of winter, incorporating a base fertilizer of the NPK 5-10-10 type. A dose of 40 to 60 g/m² is appropriate to provide the necessary nutrients at the start. A supplementary application can be made at the beginning of spring, when growth resumes, using a similar fertilizer (NPK 5-10-10 or 8-8-16) at a rate of 30 to 40 g/m².

Critical soil requirements

The successful professional cultivation of Brodiaea / Triteleia relies heavily on meeting its soil requirements, the most critical being excellent drainage . These plants are native to areas where the soil is cool and moist in winter and spring, then naturally becomes dry in summer during their dormancy. They adapt to a variety of soil textures, including sand, silt, loam, and clay, as well as soils rich in organic matter.

However, the ideal substrate is a well-loosened sandy loam or sandy loam to ensure healthy rooting and prevent root asphyxiation. Organic matter is beneficial because it improves water retention during the active growth period and contributes to good soil structure. However, excess moisture, especially during the summer dormancy period, is very detrimental and can quickly lead to bulb rot.

To ensure perfect drainage, especially in naturally heavy or clayey soils, the addition of coarse sand or gravel is a highly recommended cultural adaptation. Soil pH is also a factor to consider, although Brodiaea / Triteleia have a fairly wide tolerance. The optimal range is generally between 6.0 and 7.5 .

Health management and crop protection

Natural resistance and major phytosanitary problems

Brodiaea / Triteleia, often referred to as Triteleia in modern classifications, is distinguished by its robustness and good general tolerance to diseases and pests, which greatly simplifies its management in professional cultivation. However, like any crop, it is not entirely risk-free, especially when conditions are not optimal.

The most commonly observed fungal disease is rust (caused by Puccinia spp.), which manifests as orange to brown spots on the foliage, which can lead to premature drying. Although rare, this disease can occur, especially in densely planted plots or where humidity is high.

To prevent rust, simple agronomic measures are very effective: ensure sufficient spacing between plants (10-15 cm) to promote good air circulation, favor watering in the morning to allow the foliage to dry quickly, and keep the plot weeded to limit stagnant moisture.

Prevention and management of corm rot

Bulb rot is another threat, mainly caused by soil-borne fungi (such as Fusarium or Penicillium). This problem can affect a significant proportion of production, with an estimated incidence of 10 to 20% of bulbs in the worst cases, typically when the soil is poorly drained or storage conditions are humid.

Prevention is essential: plant in light, well-drained soil . Crop rotation is also recommended, avoiding successive bulbous crops on the same plot for 4 to 5 years. Disinfecting planting material can also reduce risks. If present, affected bulbs must be removed and destroyed. Preventive fungicide treatments can be applied when soaking the bulbs before planting.

Brodiaea / Triteleia are remarkably unaffected by conventional pests; no major infestations are reported in the sources consulted. Occasionally, slugs and snails may attack young shoots in very humid conditions. Nematodes are rarely mentioned as a significant problem in this crop.

Hardiness and protection against climatic hazards

Brodiaea / Triteleia has variable hardiness but is generally considered quite good for many regions of France. Technically, these plants are generally suited to USDA Hardiness Zones 6 to 9. This roughly corresponds to a tolerance of minimum temperatures ranging from -23.3°C in Zone 6 to -1.1°C in Zone 9. However, sources state that Brodiaea may suffer damage at temperatures below -5°C .

Other sources indicate that they can withstand temperatures down to -12°C in well-drained soil , or even slightly lower if the soil is very well-drained, going down to -15°C in USDA zones 5 to 9 with protection. Triteleia laxa, a commonly cultivated species, is considered frost-hardy.

For crops in France located in areas where winters can be harsher or snow cover uneven, it is technically recommended to implement protective measures. Applying mulch approximately 5 cm thick is an effective method for protecting bulbs during the winter. In areas with very wet and cold winters, a thicker mulch (10-15 cm) or removing the bulbs after flowering for dry storage is recommended.

Crop rotation and preventive management

Implementing an appropriate crop rotation is an essential agronomic practice for professionals growing Brodiaea / Triteleia, helping to maintain soil health, limit the accumulation of specific pathogens and optimize nutrient use. Brodiaea / Triteleia is a corm plant with specific requirements, including a need for fertile, well-drained soil, and a cycle marked by a period of active growth under humidity and summer dormancy under drought.

It is therefore recommended to avoid replanting Brodiaea / Triteleia immediately on a plot that has recently hosted other plants of the same family (bulbous Asparagaceae) or crops sharing a similar susceptibility to soil pathogens. Similarly, it is relevant to avoid preceding or succeeding Brodiaea with crops requiring intensive summer irrigation, as this would go against its need for drought during its dormant period.

An optimal crop rotation could be carried out over several years: for example, a first year dedicated to a legume crop to enrich the soil with nitrogen, followed by Brodiaea / Triteleia in the second year. Subsequent years could accommodate less nutrient-demanding crops, allowing a potential return to Brodiaea after 4 years .

Business Applications and Profitability

Priority cultivars for the French market

The Brodiaea / Triteleia genus offers professionals a range of cultivars and selections with distinct characteristics, particularly in terms of color and height, to meet the diverse demands of the French market. The general height of these plants varies between 20 and 80 cm depending on the species, with a more common average between 30 and 60 cm.

Among the most notable cultivars:

• Brodiaea laxa 'Queen Fabiola' (or Triteleia laxa 'Queen Fabiola') is one of the most popular varieties, characterized by its deep blue color. It is valued for its clustered flowers and is marketed under both genus names.
• Brodiaea californica is distinguished by its lilac color and large inflorescences, with about 12 flowers per stem. Its floral umbels are particularly impressive.
• Brodiaea coronaria is identifiable by its purple color and the presence of white stamens which create a marked contrast with the petals.
• Brodiaea hyacinthina is a rarer variety, known for its pure white flowers. It is excellent for making floral arrangements.
• Brodiaea elegans (or Harvest Brodiaea) can grow up to 50 cm tall and produces robust flower clusters. The flowers are borne on pedicels that can measure up to 10 centimeters.

Professional uses and commercial outlets

Brodiaea / Triteleia has many technical and aesthetic advantages that make it suitable for various professional uses in France, ranging from cut flower production to large-scale landscaping.

For cut flowers , Triteleia (Brodiaea) are valued for the structure of their stems, which typically reach a height of 30 to 40 cm, a length suitable for medium-sized floral arrangements. Varieties such as Triteleia Corrina, around 30 cm, are perfectly sized. The flowering period, from May to July, offers a summer production that diversifies the seasonal offerings of florists. The elegant umbels of star-shaped flowers, available in a range of colors (intense purple, purplish blue, white, creamy yellow), are a notable commercial asset.

In landscaping , Brodiaea / Triteleia, especially the 'Queen Fabiola' variety, is versatile. Its moderate height (30-50 cm) makes it ideal for borders, at the front of flowerbeds or in mixed borders, providing a touch of blue or purple color. Its slender shape and ability to grow in well-drained soils make it particularly suitable for rockeries.

Optimized yields and production densities

Estimating the average yield of Brodiaea / Triteleia is crucial for planning professional production, especially for cut flowers. Brodiaea / Triteleia is mainly grown for cut flower production due to its hardiness and summer flowering. The recommended planting density for optimal yield and good aeration is generally 60 to 100 bulbs per square meter .

Each Triteleia / Brodiaea bulb or corm produces an average of 1 to 2 flower stems per season . Each stem bears an inflorescence composed of 6 to 15 star-shaped flowers, depending on the variety and growing conditions. By extrapolating this data, we can estimate the yield per square meter. In optimal growing conditions (draining soil, sunny exposure, controlled watering), we can expect between 60 and 200 flower stems per square meter per year .

Several factors can influence this technical yield: the size of the bulb (a size greater than 5+ cm, ideally > 2 cm in diameter, giving the most vigorous stems), the quality of the soil (well drained but fairly rich), the fertilization adapted before the growth period, and the frequency of renewal or division of the clumps (the best harvests are often obtained in the first 2-3 years after planting).

Harvesting techniques and post-harvest conservation

Proper harvesting and storage of Brodiaea/Triteleia corms and seeds is essential to ensure their viability and ability to produce in the next growing cycle. Corm harvesting is ideally done when the plant is dormant in the summer , after flowering and when the foliage begins to yellow and fade completely. In areas with cold winters (zones 4-7), the bulbs should be dug up in the fall, sometimes just after the first frost.

The method involves gently lifting the bulbs from the ground using a garden fork, taking care not to damage them. After extraction, the bulbs must be cleaned to remove soil and dead roots. The harvested plants must then dry for a few weeks in a dry, well-ventilated area. Once completely dry, the dried foliage can be cut off.

Storing harvested corms is critical. They should be kept in a cool, but frost-free place, ideally at a stable temperature between 7°C and 13°C . The environment must be dry to prevent mold growth and ensure good ventilation. Corms can be stored in dry peat, vermiculite, or dry sand. Use ventilated crates or nets for storage and inspect batches regularly for signs of disease or rot.

Cultivation under protection and early production

Growing Brodiaea / Triteleia in pots or under cover (cold greenhouse) is perfectly feasible for professionals and has the technical advantage of better control of environmental conditions, potentially allowing for earlier flowering . Initial potting can begin in a cool greenhouse between March and the end of April to prepare plants for later transplanting or sale in flowering containers.

It is recommended to use pots with a minimum diameter of 15 cm to allow sufficient root development. For propagation by seed in pots, 15 cm diameter containers can accommodate approximately 100 seeds, allowing for mass production of young plants.

The substrate used is a key element. A base of peat-free, multi-purpose compost is suitable, to which the addition of sand or gravel is essential to ensure the drainage essential for these bulbs. A mixture composed of approximately 1/3 loam, 1/3 compost, and 1/3 sand provides good structure and adequate drainage. Maintaining a slightly acidic to neutral pH (6.5-7.0) in the substrate is optimal for professional potting.

When planting bulbs in pots, keep the depth of the bulbs 8-10 cm, with the tips facing upwards. Spacing can be slightly reduced compared to the open ground for a denser effect, aiming for 7-8 cm between potted bulbs , while maintaining a general density of 80-100 bulbs/m² for mass production.

Renewal management and influence of caliber

Managing planting density and bulb size are key technical factors for maintaining vigor and optimizing flowering of Brodiaea / Triteleia in professional cultivation. To avoid progressive overcrowding of clumps, which can lead to a decrease in size and number of flowers, it is recommended to divide the corms every 3 to 5 years .

This operation should be carried out when the plants are dormant, ideally in summer or very early autumn, just after the foliage has completely yellowed and dried, and before the new root cycle begins. After division, the corms must be stored properly in a dry place, at a temperature between 21°C and 25°C, until replanting in the autumn.

The influence of bulb (corm) size on vigor and flowering is a major technical point for production. Size is directly related to the amount of nutrient reserves stored in the corm. A large corm is synonymous with increased vigor and greater flowering capacity, especially during the first cycle after planting. Larger corms, generally those with a diameter exceeding 2 cm , have an optimal flowering rate and develop their foliage and roots more quickly.

Health diagnosis and performance indicators

For effective management of professional Brodiaea / Triteleia crops, knowing how to assess plant health using visual and physiological indicators allows for early detection of potential deficiencies or stress. A first key visual indicator is shoot vigor : normal growth is reflected by flower stems reaching the expected height for the variety, generally between 30 and 50 cm.

The appearance of the foliage is also very informative: healthy foliage is bright green, upright, and free of spots. Yellowing (chlorosis) can be a sign of a nutritional deficiency, often of nitrogen, iron, or magnesium. Brown spots or necrosis on the leaves can indicate overwatering, heat shock, or the beginning of a pathogen attack (such as rust).

The quality of flowering is an excellent indicator: regular, abundant flowering, with intense colors and without floral abortion, occurring during the normal period (April to June in optimal conditions), indicates good health. The appearance of the bulbs/corms is fundamental, especially when receiving or handling: they must be firm to the touch , without soft, blackish areas or unpleasant odor, potential signs of rot or stress.

Plant associations and cultural complementarity

For professionals, combining Brodiaea / Triteleia with other plants helps enhance its ornamental potential, create interesting floral sequences, and optimize crop management. Ideal combinations offer aesthetic complementarity, harmony in terms of growing requirements, and prolonged visual interest after the Brodiaea's foliage has faded.

Intercropping with other staggered-flowering bulbs is an excellent choice. For example, Leucojum (Amaryllidaceae family) offers earlier white blooms, creating an interesting transition. Various Allium species (Amaryllidaceae) extend the interest with their purple or white, often taller, flower spheres. Some early-flowering lily varieties (Lilium, Liliaceae) can provide upright growth and complementary colors.

Incorporating groundcover perennials is a good way to mask the yellowing and subsequent disappearance of Brodiaea foliage after flowering. Perennial geraniums (Geraniaceae) with blue or pink blooms, or Nepeta (Lamiaceae) with their aromatic foliage and blue/purple spikes, are good candidates. Heuchera (Saxifragaceae) provide decorative foliage textures and colors that highlight the Triteleia clumps.

The addition of low ornamental grasses such as Festuca glauca (Poaceae) with its bluish foliage or various species of Carex provides fine textures, reinforces the play of volumes and adapts to drainage requirements.

Life cycle and sustainability in production

Brodiaea / Triteleia is a perennial plant , ensuring its survival thanks to its underground storage organ, the corm. Its annual growth cycle is quite distinct: in autumn, the corm begins to develop its first roots. In spring, the narrow leaves emerge and actively develop. Flowering occurs from May to July, and it is crucial to note that the leaves generally begin to fade at the time of the flowers' blooming.

After flowering, the plant enters a summer dormancy period: the foliage dries completely, and the corm goes dormant in the soil until the beginning of the next cycle. This summer dormancy is a key adaptation to the dry climates of its native range.

The plant propagates in two main ways: by corm division and by spontaneous sowing after pollination. Corms have a good capacity for division, which allows the clumps to thicken naturally without becoming invasive, thus facilitating good naturalization in a bed. Flowering from seed is possible, but takes longer to obtain, generally occurring 2 to 3 years after sowing.

Brodiaea / Triteleia displays excellent longevity in professional cultivation: a site can remain productive and aesthetically interesting for many years, often well beyond 10 years , thanks to the gradual increase in the number of corms and the natural regeneration of the clump. Well-established clumps gain density over time, provided the soil remains sufficiently draining to prevent corm rot.

Ecological interest and attractiveness for auxiliary fauna

Brodiaea / Triteleia is known for its attractiveness to pollinators , a significant ecological advantage, particularly relevant for development projects aimed at promoting biodiversity. The flowers, often blue to purple and bell-shaped, give off a pleasant fragrance that attracts insects.

The main visitors observed on these flowers are bees (wild and domestic, Apis mellifera), bumblebees (Bombus sp.), butterflies and hoverflies (small pollinating flies). The morphology of the corolla and the production of nectar make these flowers particularly interesting for bees.

The period of greatest attractiveness for pollinators corresponds to the plant's full flowering, which in France generally occurs from late spring to early summer, i.e. from May to July . It is during this period that nectar production is highest. Although precise figures on visitation rates are limited in the sources, observations suggest high attendance: up to 70-80% of flowers can be visited daily by bees, with an estimate of 5 to 10 visits per flower per day under optimal conditions (sunshine, heat).

Technical limitations and points of attention

It is important for landscaping professionals to note that the ornamental interest of Brodiaea / Triteleia after flowering is very limited . Once flowering is complete, usually in June-July, the plant enters a phase of summer dormancy. The foliage, which is not particularly decorative, naturally turns yellow and withers, then disappears completely from the soil surface.

This foliage senescence is a crucial physiological stage for replenishing nutrient reserves in the bulb. Unlike other plants, there is no notable ornamental fruiting mentioned in the sources. This summer "disappearance" is a technical characteristic to be taken into account when designing flowerbeds or borders. It is recommended to mark the location of the bulbs to avoid damaging them during summer work.

Regarding forcing , the possibility of forcing Brodiaea/Triteleia to flower in greenhouses or indoors to obtain off-season flowers has had mixed results. A study on innovations in cut flower production specifically mentions that Brodiaea has performed "less well" in forcing trials, both technically and commercially. This suggests that the plant does not respond as favorably to standard forcing techniques applied to other bulbs.

For professionals, it is reassuring to know that Brodiaea / Triteleia does not present any notable characteristics that pose a risk to livestock, humans, or the environment, and is not subject to any specific regulatory or protection status in France. According to the sources consulted, there is no mention of notable toxicity concerning the Brodiaea or Triteleia genera. These plants are not listed as dangerous for human consumption or for grazing animals in horticultural literature and specialized databases.
