Epimedium x youngianum "Jenny Wren"
This is one that I added to my garden several years ago, chosen mainly for its name. I was glad I did, too, because it has so much more going for it than it name, although that's pretty cute, too. The flowers are soft pink, large, and the leaves are lightly speckled like like a robin's egg. It grows from 12 to 15 inches high; it's deciduous and clumping and couldn't be prettier. Zones 5-8.
