In spring, the plant reaches about 18 inches, is capped by one or two leaves. The leaves are deeply lobed and held parallel to the ground.
So where are the apples?
If you come across a colony of May Apples during a spring stroll, peek under the leaves. Where the stem divides to make two leaves, you might find a May Apple flower -- a single waxy, white bloom about 2 inches across. Fruits are supposed to follow flowers, which are blooming about now, in Michigan. Don't be surprised, however, to find far fewer fruits than there were flowers. In fact, you may find no fruit at all.
If you do find a fruit, take care before biting into it; that is what my reference material advised. This plant is strong medicine, too easily taken in toxic doses by those unfamiliar with its use. All parts of the plant are toxic, except the ripe fruit. Unripe May Apple fruit is toxic, as are the seeds; don't chew them. May Apple's roots, when processed correctly, contain an ingredient which can be used to induce vomiting. Other compounds in May Apples inhibit cell division, and a modified extract of the plant is used to make an anti-cancer drug. The resin from May Apples is used for treating warts, too, I read.
Folklore: (let's get back at the men, now, shall we???) This plant was once called 'the witch's umbrella' and thought to be used by them as a poison. The English version of this plant has much lore told about it, being called Mandrake ("man root") and believed to be alive - its screams when pulled from the ground would render a man permanently insane!
