Epimedium sempervirens "Okuda's White"
There's just something about the white-flowering Epimediums that I am most drawn to, and large-flowered "Okuda's White" is no disappointment. This one was introduced from Japan in the 1970's and spreads by rhizomes, making it a semi-evergreen ground cover over time. "Okuda's White" grows to eight inches tall. It may need protection at Zones 5 and below. Quarts. (Photo courtesy of Garden Vision Epimediums)
