Mayapple ( Podophyllum peltatum ) is a shy plant, hides her single flower beneath her two-leafed umbrella. The flower appears in late April or early May in our fold of the mountain. The "apple" won't be ripe before summer. I've read that it is tasty when ripe and deadly when green. I can't tell you so from experience, but I can tell you that mayappple transplant easily and that if you have patience for a few years, one will make a hundred. Henry's books .
