Kirengeshoma palmata - Quarry Hill Form


Add to wishlist Remove from wishlist
A collection from Japan by Quarry Hill Botanic Garden of this indispensable summer-flowering, beefy perennial. This is a rare opportunity to obtain this species with wild-origin provenance. Yellow flowers of substance like small shuttlecocks are held well above the leaves on upright stems in midsummer. Still remember being awestruck by a superb specimen at the Minnesota Landscape Arboretum years ago.
