Jack-in-the-Pulpit
Often found growing on the forest floor in its native North America, jack-in-the-pulpit (Arisaema triphyllum) is another corm plant that voles avoid. Jack-in-the-pulpit is a good foliage plant for spring and summer, but it also bears brightly-colored berries in fall.
It is perfect for Americans seeking native perennials for shade gardens.
