Care

Exposure

Place your tassel hyacinth in full sun or partial shade for optimal flowering. This plant appreciates well-lit areas, especially in temperate climates. It also tolerates light partial shade.

Watering

Water regularly during spring growth through flowering. Once established, the tassel hyacinth needs little water and is satisfied with natural moisture. Drastically reduce watering in summer after flowering, as the bulb enters dormancy.

Soil

Opt for well-draining soil, even if chalky or slightly poor. The tassel hyacinth appreciates light soils and hates stagnant moisture in winter. If your soil is too heavy, lighten it with sand or gravel.

Fertilizing

Apply balanced fertilizer in spring when vegetation resumes. One annual application is enough; this plant is not demanding. You can also incorporate light compost when planting.

Pruning and cleanup

Remove spent flowers to encourage new flower stems. Let the foliage yellow naturally before cutting it down to ground level. This allows the bulb to recharge its reserves for the following year.

Diseases and pests

The tassel hyacinth is generally robust and little affected by diseases. Watch for excess moisture that could promote bulb rot. Slugs and snails can damage foliage in spring; fine mulch or traps offer protection.

Off-season watering

In autumn, plant bulbs in slightly moist soil and keep it that way until the first shoots appear. Once flowers fade and foliage dries out, cease watering almost entirely in summer.

Did you know?

The tassel hyacinth owes its name "comosum" (from Latin "comosus", hairy) to its curious inflorescence: a dense spike of regular blue-violet flowers is topped with sterile violet flowers transformed into tendrils. This ornamental and strange particularity makes it a highly recognizable botanical curiosity in Mediterranean gardens since antiquity.

Where to buy it

Plant the bulbs in autumn for spring flowering. Pick a plant with healthy foliage and roots that are not exposed. Best time: from September to November.
