EPIMEDIUM (Bishop's Hat, Barrenwort). This is a classy groundcover
for dry shade, enjoying a bit of a fad right now, due to some
new species found in China. Tiny mitre-shaped blossoms in
May are held above delicate apple green foliage. Some foliage
develops a reddish blush with maturity. For connoisseurs,
we are propagating some of the new discoveries. In the meantime,
these are all satisfying:
