Allium macrostemon is
a perennial found in fields, roadsides, or banks. Its bulbs
are spherical, 1-2cm in diameter, enveloped with membranous
coats, and radical leaves are borne from which are linear,
25-30cm in length, in the shape of a cross-section of a
crescent. Flower stalks from the bulbs grow to 50-80cm tall,
with 2-4 leaves on the lower half parts and many light
purple flowers on them in an umbel way. The inflorescences
sometimes bear propagules among the flowers. Occasionally,
however, they form only propagules only. Bloom time:
May-June.
