This technical presentation details the characteristics of the species and the optimal conditions for its professional cultivation in France, based on precise data from available technical sources.
Botanical and taxonomic data of Ipheion uniflorum
Validated name, synonyms and botanical family
Botanically, the full and validated name for the Spring Star is Ipheion uniflorum . This species also has synonyms sometimes encountered, such as Tristagma uniflorum or Triteleia uniflora . The classification of its botanical family has been the subject of debate, with some sources attaching it to the Liliaceae , others to the Amaryllidaceae , within the subfamily Allioideae , or even to the Alliaceae according to the IPNI.
Natural geographical origin
It is a bulbous plant native to South America , specifically the temperate regions of central-eastern Argentina and Uruguay.
Morphology and agronomic characteristics
Bulb: structure, multiplication, resistance
The storage organ of the Ipheion is a true bulb, of the tunicate type . Small in size, it is generally ovoid or ellipsoidal, measuring between 1.5 and 2.5 cm in diameter at maturity. Its outer tunic is dry and papery, brown to light beige in color, sometimes slightly silvery or golden. The interior, fleshy, is whitish. These bulbs multiply easily by natural division, producing lateral bulbils . A notable advantage is their resistance to rodents and deer .
Foliage: type, cycle and characteristics
The foliage of Ipheion uniflorum is linear and semi-erect , resembling blades of grass. The leaves are narrow, measuring 10 to 20 cm long and 2 to 4 mm wide. They have a fine, supple texture. Their color is a clear to medium green , without noticeable variegation. A distinctive characteristic is the onion or garlic odor they give off when crushed. The foliage is deciduous , appearing in late winter or early spring, persisting through flowering, then turning yellow and disappearing completely in late spring or early summer.
Flowering: shape, dimensions, colors, fragrance
The star-shaped flowers are the main attraction of the Ipheion. They are composed of 6 tepals fused at the base, then clearly separated. Each flower generally measures 3 to 4 cm in diameter, or even 4 to 5 cm depending on the source. They are carried at the end of thin flower stems reaching 7 to 15 cm in height. The dominant color varies from pure white to pale blue, lavender blue, purplish blue or periwinkle blue. Some horticultural cultivars offer shades of pink or violet. The tepals often have a darker midrib . They give off a pleasant, spicy or slightly sweet fragrance .
General habit, height and width of the adult plant
Ipheion uniflorum grows low and forms a vigorous clump . At maturity, the plant reaches a height of about 20 cm, while the flower stems rise between 10 and 15 cm above the foliage. The general habit is described as spiky, especially for the cultivars 'Alberto Castillo' and the botanical form. The width of a mature clump is about 10 cm.
Biological cycle and longevity in horticultural conditions
Seasonal course of the growing cycle
Ipheion is a perennial bulbous plant, capable of living and flowering for several consecutive years. Its typical cycle begins with the development of foliage in autumn or winter , followed by flowering in late winter and spring. After flowering, the foliage turns yellow and the plant enters summer dormancy . The bulbs multiply spontaneously, allowing the clump to thicken and persist.
Duration and precocity of flowering
Flowering is a major highlight of Ipheion for professionals. It is early and extends over a long period. It generally begins as early as February, reaches its peak in March to April, and can last until May. The total flowering time is about 8 weeks . In mild climates or in protected cultivation, the first flowers can appear as early as November. Each bulb produces several flower stems, which contributes to the abundance of flowering.
Ecological conditions and crop management
Natural habitat and climatic requirements
Native to Argentina and Uruguay, Ipheion uniflorum grows naturally in meadows and rock gardens , in open, sunny environments or on partially shaded edges. Its native range is characterized by a temperate climate , with mild to moderately cold winters and hot summers. The average annual rainfall is 800 to 1000 mm, well distributed, ensuring cool soil during the growing season .
Hardiness in French conditions
Ipheion is a hardy plant , capable of withstanding frost down to -15°C for the typical species, or even -20°C for certain cultivars such as 'Wisley Blue'. This allows it to be planted in open ground throughout France (USDA zones 5 to 9). In areas with harsh winters , the use of 4 to 5 cm of organic mulch is recommended after the first frosts to limit the effects of freezing/thawing.
Soil structure, drainage and optimal pH
The main requirement for Ipheion is well-drained soil . Excessive winter moisture is fatal. Sandy loam is ideal. In clay soil, deep amendment with neutral compost improves permeability. Very sandy soils can be enriched with peat. The optimum pH is between 6.5 and 7.0, with a tolerance of 6.0 to 7.0.
Recommended light exposure
Ipheion is adaptable but prefers full sun to partial shade . It requires at least six hours of direct light per day for optimal growth and flowering . Partial shade is tolerated but reduces flower yield.
Professional planting window in France
Planting bulbs is done in autumn , from September to November , when the soil temperature exceeds 8 to 10°C . This encourages good rooting before winter.
Planting depth and density
The bulbs should be planted at a depth of 5 to 10 cm (ideally 7 to 8 cm), with a spacing of 5 to 10 cm. For a rapid ground cover effect , use a reduced spacing of 5 cm .
Watering according to phases and fertilization needs
Watering needs are moderate but regular during autumn and spring. The soil should be slightly moist but not soggy. During the flowering period, the recommended water intake is 30-40 mm/week. During summer dormancy, drastically reduce watering .
For fertilization , the incorporation of well-rotted compost (2-3 kg/m²) before planting is beneficial. At the vegetative restart, an NPK 10-10-10 (30-40 g/m²) is recommended. In active growth: NPK 10-5-15 (20-25 g/m²). Before flowering: NPK 5-10-15 (20-30 g/m²). After flowering: NPK 5-5-15 (15-20 g/m²). Never put fertilizer at the bottom of the hole .
Routine maintenance, division and removal of foliage
Maintenance is minimal: well-drained soil and moderate watering are sufficient. Divide the clumps every 5 years in early summer . The foliage should be left in place after flowering to replenish reserves. Cutting should only take place when it has completely faded. Removing faded flowers is optional.
Managing extreme conditions: cold, drought, pot growing
In case of autumn or spring drought , keep the soil slightly moist. In harsh winters, plant 10-15 cm deep, add 5 cm of mulch. When growing in pots , very draining substrate based on peat, loam and perlite, moderate watering, liquid fertilization every 7-10 days.
Vernalization necessary for flowering
Ipheion requires a cold period to induce flowering. Exposure between 2°C and 7°C for 6 to 8 weeks seems adequate by analogy with other bulbs.
Specific conditions in soilless cultivation
In pots, you need a well-draining substrate (potting soil + peat + sand or perlite). Let the top 2.5 cm dry out before each watering. During summer dormancy, keep the pots cool, shaded and dry , or remove the bulbs.
Multiplication and yield in the nursery
Vegetative propagation by bulbils
Vegetative propagation is the preferred method: each bulb produces 1 to 3 bulbils/year under good conditions. A bulbil reaches flowering in 1 to 2 years.
Propagation by sowing and yields per m²
Sowing is possible but less reliable for preserving varietal characteristics. Flowering occurs after 2 to 4 years . For a rapid ground cover effect, plant 80 to 100 bulbs/m² . In 2 to 3 years, a clump can triple in size .
Varietal offer: main cultivars available
Several horticultural cultivars are available:
-
'Alberto Castillo' : pure white flowers, large, very hardy.
-
'Rolf Fiedler' : intense blue, fragrant, thick foliage.
-
'Jessie' : very dark blue, close to 'Rolf Fiedler'.
-
'Tessa' : dark pink, recent selection.
-
'Wisley Blue' : lilac blue.

Post-flowering ornamental value
Weak. Foliage naturally yellows. Do not cut before complete wilting . Edible flowers and leaves (use not developed).
Regulatory, health and safety aspects
According to available sources, Ipheion uniflorum has no known toxicity to humans, domestic animals, or livestock. It is not listed as a protected or invasive plant in France. Its marketing and cultivation are therefore free. It is known to be robust and not very susceptible to major diseases or pests .
Bulb harvesting and storage conditions
Bulb harvesting takes place in summer (June-July) , when the foliage is completely yellow and dry, indicating dormancy. The bulbs must be carefully dug up , cleaned and sorted. This is the time to carry out division , separating the bulblets .
For storage, store the bulbs in a dry, dark, well-ventilated place at a stable temperature (15-20°C) . Use well-ventilated containers (crates, paper bags). Ipheion does not tolerate prolonged storage well , so it is recommended to replant quickly after harvesting or receiving.
For seed harvesting (breeding or hybridization use), sow immediately after harvesting ripe capsules (May-June).
Long-term crop management
Crop rotation and recommended precursors
Professional success depends on well-drained soil with a neutral pH . Avoid previous crops that leave poorly decomposed organic residues (fresh manure, hot compost). Do not replant after crops that are very sensitive to slugs and snails .
Visual indicators of plant health
A healthy bulb is firm and uniform in color (creamy-white to beige). The leaves should be green and ribbon-like (20-30 cm). A long flowering period (8 weeks), with several stems per bulb , is a sign of good health. Water stress manifests itself as wilting (underwatering) or premature yellowing (overwatering).
Nutrient deficiencies are manifested by pale foliage (nitrogen), purplish (phosphorus), or yellowed edges (potassium). A soft texture, strong odor, or discoloration of the bulb indicates rot due to excessive moisture.
Caution: Summer yellowing after flowering is natural and should not be confused with a deficiency or stress.
Influence of bulb size on production
Bulb size determines vigor and flowering capacity in the first year. The standard professional size is 4/+ cm . A size of 5/+ cm provides denser flowering and more vigorous plants. Sizes smaller than 4 cm produce few or no flowers in the first year, requiring several seasons to reach maturity .
