About
Hyacinthus orientalis, the common hyacinth, garden hyacinth or Dutch hyacinth, is a species of flowering plant in the family Asparagaceae, subfamily Scilloideae. It is native to western Asia, from southern Turkey, through Syria and Lebanon to northern Israel. It was introduced to Europe in the 16th century. It is widely cultivated everywhere in the temperate world for its strongly fragrant flowers which appear exceptionally early in the season, and frequently forced to flower at Christmas time.
How to grow it
H. orientalis has a long history of cultivation as an ornamental plant, grown across the Mediterranean region, and later France (where it is used in perfumery), the Netherlands (a major centre of cultivation) and elsewhere.
It flowers in the early spring, growing best in full sun to part shade in well-drained, but not dry, soil. It requires a winter dormancy period, and will only persist in cold-weather regions. It is grown for the clusters of strongly fragrant, brightly coloured flowers. Over 2,000 cultivars have been selected and named, with flower colour in shades of blue, white, pale yellow, pink, red or purple; most cultivars have also been selected for denser flower spikes than the wild type, bearing 40–100 or more flowers on each spike.
Safety
All parts of this plant are reportedly toxic to humans and animals if ingested.
