About Hyacinthus orientalis 'Woodstock'

Hyacinthus orientalis 'Woodstock' · also called Woodstock hyacinth, burgundy hyacinth · flowering

Hyacinthus orientalis 'Woodstock' is a striking Dutch hyacinth with a dense spike of deep beetroot-purple to wine-red, richly scented flowers in mid-spring. Growing 20-30 cm tall, it makes a bold container, border or forced indoor bulb. Plant in autumn for fragrant spring colour. The bulbs are toxic to cats and dogs.

Mature size: 20-30 cm tall with an 8-10 cm spread; the spike is fullest in the first season after planting.

Indoor size vs how big it gets in the wild

Hyacinthus orientalis 'Woodstock' is a naturally small plant — it stays shelf- and desk-sized for its whole life, so it never becomes a space problem. Indoors and in a pot, expect 20-30 cm tall with an 8-10 cm spread. In the ground with no restriction it is a completely different plant — the spike is fullest in the first season after planting. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Hyacinthus orientalis 'Woodstock' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: apply a balanced or high-potassium bulb feed at planting and as spikes emerge. after flowering, liquid feed every 2 weeks until the foliage dies back to rebuild the bulb. keep nitrogen moderate to avoid soft, rot-prone growth.

Feed lightly through the growing season; this plant simply will not race however hard you push it.

Light is almost always the ceiling. The hyacinthus orientalis 'woodstock' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When hyacinthus orientalis 'woodstock' outgrows the room (or the pot)
