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:
