Epimedium × rubrum

Bishops caps, red epimedium, red barrenwort, bishop’s caps

About plant names...

This is a cultivar, introduced (apparently) for better winter tolerance. They are popular as ground covers in shaded areas of gardens, but they are not found in the wild. "Bishops’ caps" refers to the dainty flowers, which resemble a bishop’s mitre (though I don't see much of a resemblance).

Identification: Rubrum comes from the red-tinted, heart-shaped leaves. Leaves are 1-1½" (2.5-3.8 cm) long, with serrated edges. Bishop's caps are 8-13" (20-33 cm) in height, and about 12" (30 cm) around. Flowers are copious, each about ¼" (6.3 mm) around, with four white pink-edged petals.
