Plant Common Name

General Description

The tasseled flower clusters of this small bulbous perennial are one of the most charming signs that spring has arrived; the spreading carpets of blue bring cheer to gardeners everywhere. Shaggy tufts of purplish-blue sterile flowers appear at the tips of straight stems, above greenish brown fertile flowers. The flower stalks emerge in mid spring from basal clumps of fresh green leaves. This grape hyacinth is native to dry meadows in southern Europe, Iraq, and Turkey.

Plant the bulbs of tassel grape hyacinth at a depth of two times their width in well-drained, moderately fertile soil and full sun. If they become crowded, lift and divide them in summer or early fall while they are dormant (mark the site while the plants are in leaf). Plant this cheery grape hyacinth in masses in the mixed border or rock garden, or naturalize it under deciduous trees. It is also very easy to force indoors for spring color in the winter.
