Gardeners' Notes:

Neutral Fledgeling On Jan 10, 2008, Fledgeling from Huron, SD wrote:

The species is a clump forming perennial. A handsome shade plant with large long-stalked leaves. The abundant flowers that arise in summer are bell-shaped flowers with narrow cream to yellow petals that give a generous display on established clumps. For the moist shaded woodland garden in a fertile but well-drained position. Propagate by seed or division in spring. Uncommon in cultivation, its hardiness limits are somewhat untested, but is known to be hardy to atleast 14F.

Peltoboykinia is listed as a rare plant on the red list. The name Peltoboykinia refers to the plants distinctive shield shaped leaf ( peltate) and the assumed close relationship to the genus Boykinia. However the similarities are now known to be superficial; the plants are only distantly related within the family, and presumably inherited their similar primitive features from a early but separate divergence.
