The best Echinacea cultivars for sale today are the E. purpurea cultivars. There are too many to list in a single article so this article series breaks them up alphabetically. E. purpurea are the hardiest and most adaptable of all of the Echinacea, and they are great-as long as you like purple.

Echinacea purpurea ‘Alba’: White flowered form of the purple coneflower (Sun to light shade, Zone 3-8)

Echinacea purpurea ‘Avalanche’ PP 18,597: The best compact, single white-flowered coneflower in our trials. This Arie Bloom hybrid makes a tight clump, adorned in summer with 20″ spikes of large, white, horizontally-held petals…quite nice! (Zone 4-9)

Echinacea purpurea ‘Bright Star’ (syn: Echinacea purpurea ‘Leuchstern’): This superb seed strain of our native coneflower is a bit taller than most (to 3-4′) and has a slightly larger and more horizontally held rosy purple petals. The small winter rosettes give rise in mid summer to see thru spikes of large pinkish daisies…great for naturalizing! (Zone 3-8)

Echinacea purpurea ‘Cotton Candy’ PPAF: Large, pink, pompon flowers.

Echinacea purpurea ‘Crimson Star’: Crimson-lavender petals.

Echinacea purpurea ‘Cygnet White’: This is a new and outstanding dwarf, white flowered selection of the 1998 Perennial Plant of the Year. In midsummer, the small rosettes of foliage send up flowering stems that are topped with stunning white coneflowers… best when used in a mass planting or blended into a perennial border. (Sun to light shade, Zone 3-8)

Echinacea purpurea ‘Fatal Attraction’ PP 18,429: This new selection of our US native Echinacea purpurea is from Piet Oudolf’s famed garden in Holland. Echinacea ‘Fatal Attraction’ is unique because of the 26″ tall sturdy wine black stems that hold the intense pink flowers…a favorite of garden visitors. Flowering begins in late June…be patient. (Zone 3-9)

Echinacea purpurea ‘Fragrant Angel’ PP 16,054, PVR: This sturdy new coneflower from Terra Nova Nurseries is the white counterpart of Echinacea ‘Ruby Giant’ and the best white coneflower we have ever grown. The giant 4-5″ heads of pure white petals, around a contrasting orange cone, are also deliciously fragrant. Since these are clonally reproduced, each plant is identical for a more uniform planting. (Zone 3-9)

Echinacea purpurea ‘Green Envy’: When Mark Veeder first showed me a photo of his new Echinacea purpurea seedling, I thought for sure this was an April Fool’s Photoshop TM creation. Only after growing and photographing the plant myself, can I say for sure, it is truly this unique. The 20″ tall stems are topped, starting in mid-June, with large 4.5″ wide flowers composed of a dark cone with a green center. Surrounding the cone, are long petals that are pink toward the cone changing to lime-green toward the downward recurving tips. Echinacea ‘Green Envy’ is so weird, gardeners will either love or hate it…we love it! (Zone 4-9)

Echinacea purpurea ‘Kim’s Knee High’ PP 12,242: From Tony’s college classmate Kim Hawks, former owner of Niche Gardens, comes a new dwarf selection of the wonderful native purple coneflower. This compact selection is the first coneflower to be vegetatively propagated, ensuring that every plant is identical…no seed-grown variation as long as you remove the old seed heads. Starting in mid-June (NC), each flower head has rigidly reflexed, rosy-pink petals that give a truly unique look to this selection. Purple coneflower is extremely drought-tolerant, although it does favor improved garden conditions. Plant a drift, sit back with drink in hand, and wait for the butterflies! (Zone 3-9)

Echinacea purpurea ‘Kim’s Mop Head’ PP 13,560: We are delighted to be able to offer the wonderful white flowered companion to Echinacea ‘Kim’s Knee High’. This mutation of Echinacea ‘Kim’s Knee High’, discovered at Sunny Border Nursery in Connecticut, has the same wonderful compact habit with perfectly symmetrical downward arching heads of fringed-white petals…what a great garden plant. Echinacea ‘Kim’s Mop Head’ looks great when planted in a mass in a flower bed or border. (Zone 3-9)

Echinacea purpurea ‘Kim’s Red Knee High’ PP 20,411: A mutation of Echinacea ‘Kim’s Knee High’, discovered at Connecticut’s Sunny Border Nursery in 2005. Echinacea ‘Kim’s Red Knee High’ has the same vigorous growth, short habit and attractively reflexed petals of its parent. The name red, however, is problematic…another example of male color-blindness and why you never ask men to describe a color. The color is actually a richer, darker pink than the parent, but nothing close to red. (Zone 4-9)

Although they are not the latest and greatest cultivars, Echinacea purpurea cultivars are still the best.
