Edible [2]  May be edible. See the Plants For A Future link below for details.
Flower Type [2]  Monoecious
Hazards [2]  No members of this genus are known to be poisonous, but when grown on nitrogen-rich soils they are known to concentrate nitrates in the leaves. This is especially noticeable on land where chemical fertilizers are used. Nitrates are implicated in stomach cancers, blue babies and some other health problems. It is inadvisable, therefore, to eat this plant if it is grown inorganically.
Lifespan [2]  Annual
Pollinators [2]  Wind, Bats
Structure [4]  Herb
Usage [2]  Yellow and green dyes can be obtained from the whole plant;
Height [2]  35 inches (0.9 m)
