How to Start It
★ Recommended for beginners
Plant outdoors about 12cm deep in autumn for fat, fragrant spring spikes in a sunny, drained spot.
Famous for its powerful sweet perfume — a few hyacinths scent a whole room or garden corner. Plant the bulbs in autumn for spring flowers; they can also be 'forced' indoors over winter in a special hyacinth glass or pot. Outdoor spikes get smaller and looser in later years (more natural-looking, but less dense). Tip: the bulbs can irritate skin, so wear gloves when handling.

Planting & Sprouting
Growing Tips
- 1Full sun and free-draining soil give the best spikes; plant in autumn about 12cm deep.
- 2Expect the biggest, densest flower spikes the first spring, then looser, more relaxed ones in later years — both are lovely.
- 3For winter scent indoors, buy 'prepared' (pre-chilled) bulbs and force them in a jar of water or a bowl of compost.
- 4Always let outdoor foliage die down naturally.

When to Pick
Fragrant spikes in spring; flowers loosen and shrink in later years
How to Harvest
- 1Cut spikes for the vase when the lowest few florets open.
- 2Outdoors, deadhead the spent spike but leave the foliage to die back naturally to feed the bulb.
- 3Forced indoor bulbs can be planted out in the garden afterwards (they won't force again but will flower outside in future springs).
- 4Wear gloves — the bulbs can itch sensitive skin.
