Description of Hemp, Wild (Cannabis sativa):
Feral cannabis is an exceptionally hardy weed, widely dispersing its seeds which can lie dormant for 7–10 years before sprouting again. Leaves are in a fan-shaped array, palmately compound in groups of 3 to 9, alternately attached at the stem, though they may be oppositely attached near the base of the plant. has both male and female flowers, usually on separate plants but both may be on the same plant. The male flowers are greenish and become cream or pale yellow with maturity, are ½-inch across when fully opened, hanging down with 5 widely spreading narrow petals and 5 creamy-tipped stamens, and loosely clustered on branching stems up to 12 inches long. The female flowers are green, stalkless, enclosed in gland-dotted bracts, and densely clustered along the stem and at the top of the plant, the pale style mostly erect.
