Mayapples grow in clusters, usually from a single root. The flowers are white, and are found under the foliage. They start growing in early spring, and flower in April and May. The fruits are harvested in the summer, depending on where you are located. The leaves remind me of Tree Stars from the first Land Before Time movie.
Again, every part of the plant, except the fully ripe fruit is poisonous. Don't eat the seeds.
