I thought this was native to the northwest, but I guess it must have come from the eastern U.S. It seems to grow everywhere except in areas of full sun. Dry, wet, sandy, clay, loamy, you name it, it grows there. On my property it grows along my driveway in the clay and gravel where it gets very dry in the summer. It also grows alongside and in the stream bed of a spring. I pulled up some of the runners (tubers?) that it sprouts from and buried them in a garden area under an apple tree and it happily spread out across that area. It's a great-looking plant, very tropical looking for this area, and very easy to grow.

I've seen this plant in several gardens, but nowhere flourishing as well as at the Garden in the Woods, Framingham MA. It's a showy plant, first for its big bold bat-shaped foliage, which it keeps through fall, second for its showy blue fruits on cherry-red stems, and third for its short-lived white flowers held just above the leaves in late May. Where happiest, it reaches 4-5' tall.

Grows from a short rhizome, but remains in a clump. The leaves, when emerging, may be attractively though transiently marked with red/brown. This genus is closely related to mayapple (Podophyllum), but doesn't share our mayapple's aggressive habits.

Needs shelter from strong winds which can damage the big leaves. Here it also needs protection at least from the afternoon sun.
