Technical presentation of Hyacinthus orientalis : a professional hyacinth culture

The common hyacinth , scientifically known as Hyacinthus orientalis , is a perennial bulbous plant highly valued by professionals for its intense spring flowering and characteristic fragrance . Belonging to the Asparagaceae family, subfamily Scilloideae , it was historically classified in the Hyacinthaceae and then the Liliaceae . This evolutionary classification testifies to the botanical richness of this species.

Origins and natural habitat

Native to a vast area of ​​the eastern Mediterranean and the Middle East, more specifically southern Turkey , Syria , Iraq (Baghdad region), Lebanon and northern Israel , Hyacinthus orientalis was introduced to Europe in the 16th century and has since become naturalized in certain Mediterranean areas, notably southern France.

It grows in open wooded edges , rocky or scrubby meadows, on well-drained soils , often calcareous or stony, rich in organic matter. It tolerates sunny or semi-shaded exposure . The typical climate of these areas is Mediterranean to continental with dry, cold winters and dry, hot summers .

The plant tolerates summer drought well, adapting to marked seasonal cycles . It is found up to 2,000 meters above sea level and grows ideally between 15 and 20°C during flowering.

Morphology and botanical characteristics

Hyacinthus orientalis is a perennial herb growing to 15-25 cm in the wild and up to 30-50 cm in cultivation . It has an upright, upright habit with a vertical flower stem and a rosette of narrow, linear leaves.

The bulb: heart of the plant

The tunicate bulb is rounded , with scales, oval in shape and large in size (diameter 10 to 20 cm ). It contains oxalic acid which can cause irritation. It has contractile roots which allow it to sink optimally into the soil.

Foliage: functional and temporary

The foliage consists of 4 to 6 leaves per bulb, linear, canaliculated , dark green in color. These leaves ensure photosynthesis and the storage of reserves for the following year. It is essential not to cut them while they are green .

Flowers: a fragrant burst

The flowering presents a dense raceme with 30 to 50 flowers depending on the variety. Each flower is actinomorphic , star-shaped, with six tepals fused at the base and six stamens . The whole is intensely perfumed .

The colors are very varied: blue/purple ('Delft Blue', 'Blue Jacket'), pink ('Pink Pearl', 'Fondant'), white ('Carnegie'), red ('Jan Bos'), pale yellow ('City of Haarlem'), peach ('Gypsy Queen').

Life cycle and longevity

Perennial, the hyacinth has an annual cycle with summer dormancy , planting in autumn , winter vernalization and spring flowering . The bulb renews itself each year with possible production of bulbils. Cultivation possible indoors or outdoors .

Hardiness and climatic conditions

Very hardy (USDA zones 3 to 9), resistant to -20°C or even -35°C with protection. In warm climates, artificial vernalization is necessary (4 to 7°C for 12-14 weeks). Well-drained soil is essential to prevent rot.

Flowering period and duration

Natural flowering : March-April. In greenhouse: December to February. Duration per bulb : 2 to 3 weeks. In flowerbeds: 2 to 3 months.

Multiplication and yield

Propagation is by lateral bulbils (3 to 5/year), or by flaking (10 to 25 bulbs in 3-4 years) or scarification (30-40 bulbils in 2-3 years). Sowing is reserved for hybridization (4 to 6 years before flowering).

Commercial bulbs : 14-16 cm in size, obtained in 3-4 years. Growing density: 40 to 60 bulbs/m² outdoors, up to 200/m² under cover.

Main cultivars and selections

Wide selection of professional cultivars : 'Delft Blue', 'Blue Jacket', 'Pink Pearl', 'Fondant', 'Spring Beauty', 'Carnegie', 'Jan Bos', 'City of Haarlem'. Average height : 20 to 30 cm. Earliness varies depending on the cultivar.

Specific features and risk management

Toxic content (oxalic acid, lycorine): toxic ingestion, irritant contact. Gloves recommended for handling. Unprotected plant and free marketing in France.

Integration into landscaping and communities

Hyacinth is ideal for spring flowerbeds , with dense planting (40 to 60 bulbs/m²) to maximize the visual and olfactory impact. Its height of 20 to 30 cm allows it to be combined with other bulbs to create effects of volume and color . It is also suitable for borders or containers .

For communities and public spaces , it represents an easy-care plant (little watering, disease resistant, low need for treatments). Its spectacular flowering lasts up to 2-3 months in a clump. Its reduced maintenance helps reduce operating costs .

Attractiveness to pollinators

Hyacinths attract bees and bumblebees with their bright colors and fragrance . Their early flowering (March-April) provides an essential source of nectar and pollen as winter draws to a close.

Recommended botanical associations

For complementary aesthetic and cultural effects , combine hyacinth with:

• tulips (height/color contrast)
• daffodils (light habit, varied colors)
• crocus (early, low carpet)
• muscari (dense carpet)
• pansies and primroses in the borders

Respect a spacing of 10-15 cm and good compatibility of requirements (drained soil, sun or partial shade).

Post-flowering ornamental interest

After flowering, the ornamental interest is limited . The foliage yellows quickly (4 to 6 weeks) while recharging the bulb. Fruiting is discreet and the seeds are rarely used. It is recommended to camouflage the declining foliage with other plants.

Hardiness and cultural adaptations

Faced with prolonged drought:

• Keep the soil slightly moist
• Use organic mulch (5-7 cm)
• Incorporate organic matter (20-30%)

Against harsh winters (< -15°C):

• Plant deeper (10-20 cm)
• Add thick mulch (8-10 cm)
• Use a wintering fleece (30-50 g/m²)

Soil requirements and drainage

The soil should be light to medium textured (sandy to loamy), with a pH of 6.0 to 7.0 . Perfect drainage is crucial to prevent rot:

• Add coarse sand if heavy soil
• Avoid mixing sand/clay directly
• Plant in a mound if necessary

Light exposure

Full sun recommended for optimal flowering. Partial shade tolerated under deciduous trees (before leafing). Avoid dense shade . Need: 6 to 8 hours of direct sunlight daily during growth and flowering.

Planting calendar

Plant in autumn (late September to October), ideally 6 to 8 weeks before the first frost . Planting is possible until December but with less flowering.

Planting depth and spacing

In open ground: 10-15 cm deep, 10-15 cm apart.

Potted: 5cm deep or half visible, with 5-6 bulbs in a 25-30cm pot .

Water and fertilization requirements

Sensitive to excess water . Maintain light humidity , never soggy:

• In open ground: 60% soil humidity
• In pot: 20-30 mm/week , with light watering

Reduce fertilization after flowering, stop when the foliage turns yellow .

Moderate fertilization :

• 30-40 g/m² of organic amendment before planting
• NPK inputs (50-60 kg/ha N, 60-80 kg/ha P ₂ O ₅ , 80-100 kg/ha K ₂ O) if necessary
• Avoid excess nitrogen , especially when forcing

---

Routine maintenance

Weeding is essential (every 2-3 weeks during growth) to limit competition .

Remove faded flowers to prevent them from going to seed, without cutting the green foliage .

Moderate watering : avoid excess.

In intensive cultivation:

• Lift the bulbs every 1 to 3 years, once the foliage is dry (end of May to end of June)
• Store in a dry, ventilated, cool (15-20°C) and dark place
• Keep humidity < 70% until replanting in the fall

Parasites and diseases

Main threats:

• Gray mold (Botrytis cinerea)
• Bacterial rot (Erwinia carotovora)

They are favored by excessive humidity and poorly drained soils and can cause up to 30-40% losses .

Pests:

• Slugs and snails on young shoots

Essential prevention :

• Optimal drainage (sand, gravel)
• Crop rotation (4-5 years without lilies)
• Strict hygiene (tools, containers)
• Healthy bulbs
• Physical protection against slugs

No effective curative treatment for bacterial rot: eliminate and disinfect.

Harvesting and storing bulbs

Harvest : late spring/early summer, once the foliage has turned yellow and dried out .

Procedure :

• Dig up carefully
• Clean and separate bulbs and bulbils
• Dry in the shade for 1 to 2 weeks
• Store at 15-20°C, 60-70% RH, in the dark until autumn

Crop rotation

Avoid replanting hyacinths or other lilies (tulips, daffodils, garlic, onions, irises) on the same plot before 4 to 5 years .

Recommended alternatives: cereals, corn, meadows .

Vernalization: a fundamental requirement

Hyacinth absolutely needs cold to flower:

• 3 weeks at 5°C minimum
• In France (USDA zones 4 to 8), natural winters are sufficient
• For forcing or in warm climates: 10 to 14 weeks at 5-9°C

Without vernalization: absent or weak flowering .

Pot culture and forcing

Substrate: light and very draining (potting soil + 15-30% sand/perlite, pH 6-7). Pots with drainage holes .

Density under cover: up to 200 bulbs/m² .

Terms :

• Rooting phase: 3-4 weeks at 9-13°C, in the dark
• Then increase the light and temperature (16-18°C)

Forcing allows for scheduled flowering (festivals, events).

Health indicators and stress

Dark green, straight and firm foliage : a sign of good health.

Symptoms of stress:

• Yellowing , wilting, brown edges
• Short or soft flower stem

A dense, colorful bloom indicates a vigorous plant. The bulb should be large, firm, and free of spots .

Specific deficiencies :

• Nitrogen (N): general yellowing
• Potassium (K): edge necrosis
• Phosphorus (P): low flowering

Renewal and influence of the caliber

Renewal of the clumps every 3-4 years is recommended to maintain the quality of flowering .

Large bulbs produce the most beautiful ears in the first year. Afterward, the ear may divide and become less dense. Renewal is crucial in intensive cultivation.
