Mayapple, also called "umbrella plant" (along with a dozen other unrelated plants), is a cute woodland plant native to east and central North America. Each 15-inch plant produces a pair of deeply-notched round leaves. At the juncture where the two leaves meet a single two-inch wide-open white flower appears in May. This is followed by a single oval-shaped fruit, not toxic when fully ripe but not palatible either. Green fruit can cause an upset stomach. Mayapples spread by rhizomes to form colonies of a uniform height. They are easy to grow in a shady area. In early fall the foliage turns yellow and dies back.
