One of the common names for Epimedium is Bishop's Hat. I don't actually know what a bishop's hat looks like, but I guess it kind of looks like an Epimedium flower.
Most of my Epimediums are just starting to put up stems from the ground that will become flowers. But this one (I don't know the name) is already flowering profusely. Epimedium is one of my favorite perennials for dry shade, but normally I don't cut them back till just about now. That becomes difficult when they've already sent up flower spikes, like this one has. The foliage looks tattered and spent, but the flowers are lovely and graceful.
