About

Mitella diphylla (twoleaf miterwort, two-leaved mitrewort, or bishop's cap) is a clump forming, open woodland plant native to northeast and midwest regions of North America.

How to grow it

This species is grown as an ornamental plant in shade gardens. It prefers wet-mesic to dry soil and partial shade.

Where it grows

The flowers produce both pollen and nectar. Due to their small size, they are mainly visited by small bees and flies: for instance, Lasioglossum sweat bees, small carpenter bees (Ceratina) and hoverflies.
