Starch grapehyacinth Starch grapehyacinth
 

Starch grapehyacinthA bulbous perennial with leaves that resemble an onion or garlic, and are sometimes confused as a grass. Starch grapehyacinth has attractive clusters of purple flowers and has escaped cultivation to become a weed of landscapes and some agronomic crops. Leaves are linear in outline, ranging from 5 to 16 inches in length and 2 to 5 mm in width. All leaves are hollow and resemble those of wild garlic but have no distinct onionlike odor. Plants have conspicuous bulbs, usually larger than those of wild garlic or wild onion. Many bottle-shaped purple flowers occur in clusters at the ends of leafless stems. Individual flowers are 4 to 7 mm long, 2-1/2 to 4 mm wide and drooping downward.
