ECHINACEA purpurea
(Purple Coneflower). 30-48". Large pinky lavender daisies
with brown centers in late summer. Species purpurea
is tallest. Cultivar Magnus
was the 1998 Perennial Plant of the Year. Magnus
is compact, grows at 30-36" and has broad, flat petals
with rich rosy red color. Bravado,
Bright Star, and
Rubinstern (NEW)
are all satisfactory varieties. The whites are less robust
than the "purples". We prefer White
Swan over White
Lustre. Cygnet
White (Baby White Swan) is 20". Kims
Knee High is a similar-sized pink and Kims
Mophead white. The whole echinacea family is native to
the U.S., hardy in Zones 4 8, and useful>
ECHINOPS (Globe Thistle). 48". June Sept., self sowing,
Zone 4. Steely blue flower heads, great with summer yellows.
Veitch's Blue has
more but smaller flower heads than the species. Taplow
Blue and Blue
Globe are other selections. Arctic
Glow is a new white-flowering form.
EPHEDRA minuta
(Miniature Joint Fir). 12. Native blue-green-stemmed
ground cover for dry areas (NOT the ephedrine species!).
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:
