Production of flower bulbs for horticultural professionals
Flower bulbs are an essential category for horticulture, green space, and floristry professionals in France. As underground storage organs, they allow plants to survive adverse seasons and offer spectacular blooms, often early or in the summer, with generally controlled maintenance once well established. Understanding the morphology and technical characteristics of these organs and the plants they produce is essential for selection, cultivation, and commercial promotion among your customers of landscapers, estate managers, municipal services, or cut flower producers.
Technical classification of underground organs
Under the umbrella term "bulb," botany distinguishes several types of underground organs, each with a specific appearance and structure that influences cultivation methods and handling. Available sources primarily describe "true" bulbs, but also other storage structures.
Tunicate bulbs: optimized protection
The most common type is the tunic bulb . It consists of concentric fleshy scales surrounded by a dry, thin protective envelope, called a tunic. This tunic provides effective protection against dehydration and mechanical injury, facilitating transport and preservation. This is the case, for example, of Allium (ornamental garlic), Galanthus (snowdrops), Ipheion , Ornithogalum and Tulips .
In Alliums, the tunic is typically white and thin, enveloping whitish inner fleshy scales. In tulips, the outer tunic is light to medium brown, with a white interior. The tunic bulb of Ipheion uniflorum is small, ovoid or ellipsoidal in shape, with a brown to light beige tunic. Ornithogalum bulbs are globose in shape, with a whitish to beige, sometimes grayish, envelope with a white interior.
Scaly bulbs: delicate handling
Conversely, some genera have a scaly or non-tunicated bulb . These bulbs are formed of imbricated fleshy scales around a basal plate, without a dry outer shell. They are generally more sensitive to drying out and require more delicate handling. This is the case of Lilium (lilies), whose bulbs are composed of large white to cream-colored scales. Camassia are also described as tunicless bulbs, with imbricated fleshy scales, ovoid to ellipsoid in shape, and off-white to light brown on the outside, white on the inside.
Corms and tubers: alternative structures
Other plants classified as bulbous for horticultural convenience grow from corms or tubers . Arum italicum grows from corms, with its main tuber measuring about 4 cm in diameter . Corydalis, depending on the species, may have a solid tuber (Corydalis solida) or a hollow bulb (Corydalis cava). Gladiolus are often referred to as bulb plants, but technically grow from corms.
Standard commercial calibers
Bulb sizes vary considerably depending on the species and cultivars. For ornamental Alliums , bulbs can measure around 5 cm in diameter (for A. aflatunense) or slightly more for larger species (A. giganteum). Ipheion bulbs are smaller, between 1.5 and 2.5 cm in diameter . Lilium bulbs have bulbs whose commercial circumference varies from 4 to 18 cm depending on the species and size. Ornithogalum bulbs are generally sold in sizes 12/14 cm in circumference . For tulips, standard sizes for professionals are between 10/11 cm and 12/14 cm in circumference .
Technical floral characteristics
Flowers grown from bulbs come in a wide variety of shapes, sizes, colors, and fragrances, providing a wide range of options for landscaping and floral production.
Floral morphology and structures
Flower shapes vary from simple cup-shaped or star-shaped to more complex structures. Flowers are lily-shaped or bell-shaped/pendulous, as in Erythronium albidum and Leucojum, or tightly clustered bell-shaped flowers in clusters such as Muscari and Convallaria . Star-shaped flowers are common, as in Ornithogalum, Puschkinia, and Anemone (with 5 to 8 petals forming an asymmetrical star). Narcissus are recognizable by their central trumpet-shaped crown surrounded by tepals. Alliums are distinguished by their spherical umbels composed of numerous small star-shaped flowers, while Eremurus have star-shaped florets along a vertical spike.
Camassia have star-shaped flowers with six tepals arranged in an elongated cluster. Bulbous irises have a characteristic six-lobed structure (drooping sepals and upright petals). Tulips generally have a cup or goblet shape, single or double. Brodiaea/Triteleia have bell- or trumpet-shaped flowers in clusters. Sternbergia have cup- or goblet-shaped flowers. Gladiolus have funnel- or trumpet-shaped flowers arranged in a spike.
Flower dimensions and yields
The size of flowers and inflorescences is also highly variable. The diameter of individual flowers can be modest, such as 0.5 to 1 cm for a Muscari floret, 2 to 3 cm for a Leucojum or Chionodoxa flower, or 2.5 cm for Eranthis hyemalis. For others, it is more substantial: 3 to 4 cm for Erythronium albidum and Ipheion, 3 to 5 cm for Camassia flowers, 2.5 to 7.5 cm for Sternbergia, 5 to 10 cm for Tulips and Narcissus, or even up to 10 cm or more for large Gladiolus varieties or Lilium flowers.
The size of the inflorescences is often spectacular: the umbels of Allium can reach 25 cm in diameter for the giant varieties. The spikes of Eremurus , composed of hundreds of flowers, can rise up to 2.50 m in height . The flower stems bear numerous flowers: 10 to 20 for Gladiolus communis byzantinus, 20 to 80 for Camassia, 20 to 40 for Muscari, 5 to 15 for Convallaria, 3 to 7 for Leucojum aestivum, 10 to 30 for Brodiaea/Triteleia, several dozen to hundreds for Allium and Eremurus, and generally several dozen for Hyacinthus.
Conversely, several species bear a single flower per stem, such as Erythronium albidum, Eranthis hyemalis, Galanthus, Leucojum vernum, Ipheion (mostly), Sternbergia, and most large-flowered Tulips and Narcissus. Bulbous irises generally bear 1 to 3 flowers per stem .
Professional color palette
The dominant color of the flowers is extremely diverse. White is common (Erythronium albidum, Ornithogalum, Galanthus, Leucojum, Convallaria), often with shades or markings (green on Leucojum and Galanthus, green streak on Ornithogalum, pink on Erythronium albidum). Bright yellow characterizes Eranthis hyemalis, Sternbergia, and is a main color in Narcissus, Lilium and Eremurus (which also offers white, orange, pink).
Blue and purple tones are very common: intense blue for Muscari, blue-violet for Camassia, pale blue to purple for Ipheion, blue-grey for Chionodoxa, a wide range of blues and purples for Hyacinthus and bulbous irises. Alliums offer a varied palette including violet, purple, pink, white, blue, yellow. Tulips have the widest chromatic range, from red to violet through yellow, orange, pink and white, with bicolor and variegated varieties. Gladiolus offer a great diversity ranging from white to violet, through pink, red, orange, yellow, and bicolors.
Commercial olfactory potential
The fragrance of flowers is a variable criterion. Some species are very fragrant , such as Convallaria (powerful, sweet), Hyacinthus (intoxicating), some Narcissus (pleasant, suave), Lilium (often very fragrant, variable intensity), Ipheion (light, spicy to sweet). Others are generally considered to be little or not at all fragrant, or with a discreet or even absent fragrance: Erythronium albidum, Eranthis hyemalis, most Allium (weak, sometimes winged fragrance), most Gladiolus (barely perceptible fragrance), most Ornithogalum, Camassia, Leucojum, Chionodoxa, Tulips (light or non-existent fragrance for most). Puschkinia is described as fragrant.
Vegetative characteristics and development
Technical leaf morphology
The foliage of bulbous plants is usually basal , meaning the leaves grow from the base of the plant. The shape is often linear, narrow, strap-like, or ribbon-like, as in Allium, Hyacinthoides, Galanthus, Hyacinthus, Fritillaria, and Puschkinia. In Eranthis hyemalis, the leaves are compound, palmate, or bipinnate, and deeply cut. In Camassia, the leaves are long, narrow, and strap-like. The leaves are usually smooth and hairless (without hairs), sometimes slightly waxy or shiny. Their color is mostly medium to dark green, sometimes grayish-green or bluish. In Lilium , the leaves are lanceolate to linear, arranged alternately or whorled, and their surface is smooth and shiny.
Vegetative cycle and temporal management
The duration of foliage presence is an important technical aspect. For many species, the foliage is ephemeral and deciduous . It appears early in spring, often with the flowers, persists during flowering, then turns yellow, dries up and disappears completely in early summer, the plant entering dormancy. This is the typical case of Eranthis, Allium (foliage often yellowing as soon as it flowers), Hyacinthoides, Fritillaria, Puschkinia. This cycle allows the plant to store reserves in the bulb for the following year, and it is crucial not to cut the foliage while it is green .
In Camassia, the foliage persists until seed formation before wilting. Lilium have mostly deciduous foliage, present from spring to late summer, with the notable exception of Lilium candidum which retains a persistent basal rosette in winter. The foliage of Allium 'Millenium' is reported to be persistent in winter. The leaves of Arum italicum are present from autumn to spring.
Development and mature templates
The general habit and height of mature bulbous plants are very varied. The habit is often upright and erect, forming a basal clump with one or more flower stems that rise above the foliage. The height can be very modest, from 10 to 15 cm for Galanthus nivalis, reaching up to 25-30 cm for some cultivars or in good conditions. Chionodoxa are also low, between 12 and 25 cm depending on the variety. Puschkinia reaches 10-15 cm and Sternbergia 10-20 cm . Muscari rises to 15-20 cm , Ipheion to 15-30 cm (flower stems 7-15 cm), Convallaria to 15-30 cm , Hyacinthus to about 30 cm (flower stem 20-30 cm).
Ornamental Alliums show a great diversity of heights, classified as low ( 20-40cm ), medium ( 45-75cm ) and tall ( 80cm and more , up to 1.5m for A. giganteum or 1m for A. Ambassador). Camassia have flower stems of 60 to 90cm , Gladiolus generally 90cm (and 60-65cm for G. communis byzantinus), Lilium have stems that can become very large, requiring staking, Lilium candidum can exceed 1 meter . Eremurus are the giants of bulbs, with flower stems reaching 1.50 to 2.50m .
Commercial applications and cultivation techniques
Development of green spaces and landscapes
Flower bulbs offer multiple uses for professionals. They are widely used for creating beds and borders in parks and gardens, bringing early or summer touches of color. The ability of certain species to naturalize , such as Puschkinia and Chionodoxa, is an asset for creating large flower areas with reduced maintenance.
Production of cut flowers
Cut flowers represent an important market for many bulbs. Species such as Allium, Gladiolus, Lilium, Tulips and Anemones are particularly popular for this use. Technical criteria include stem length and stiffness (Allium, Gladiolus, Lilium), vase life (Allium 10-15 days , Gladiolus 8-10 days ), flower quality and size, and sometimes fragrance. Some, such as Ipheion, with its shorter stems and a vase life of around 4-6 days , are better suited to small bouquets or table arrangements. The possibility of using dried flowers, as with Allium, adds commercial value.
Technical cultivation requirements
General growing requirements for bulbs include well-drained soil to avoid stagnant moisture, similar to edible garlic for Alliums. For clay soils, the addition of river sand is recommended. Full sun exposure is often preferred for optimal flowering. Bulbs are generally frost-tolerant, sometimes requiring special attention for their preservation or cultivation. Planting time is crucial, often in the fall for spring blooms.
