Gardeners' Notes:


On Aug 11, 2016, Cearbhaill from Russell, KY (Zone 6b) wrote:

I absolutely love these. The flowers hold up far longer than any others in my entire garden- weeks and weeks of color during the driest, hottest part of the year when everything else is wilting and demanding that I spend time with the hose. They do well in dry conditions, part sun conditions, and in competition with tree roots. Tall enough to peek over low shrubs and look great en masse.

This species is longer lived in the garden than E. purpurea and its hybrids. Long-blooming, and deadheading isn't necessary for extended blooming, though deadheading may help plants look tidier.

This species was thought to be extinct till it was rediscovered in the 1960's in a few glades near Nashville. It is on the Federal Endangered Species List.

"Rocky Top Hybrids" is a seed strain of E. tenneseensis and not a hybrid. It comes true from seed.

The flowers are an unusal and beautiful shade of pink. It doesn't seem to be as drought - tolerant as most Purple Coneflowers. It also seems to be tolerant of a little bit of shade. It's very pretty and a little bit different looking from most pink coneflowers.

It's a little tall and thin for my taste. The landscaper bought this instead of Echinacea purpurea. It did well in the garden, though.

ECHINACEA tennesseensis ROCKY TOP HYBRIDS Tennessee Coneflower - Med. 24" - Plant 16" apart. z3-9. A native wildflower, very useful and long-blooming in the border. Thin rays of deep pink petals around a center cone are upward facing. Looks stout and substantial in the garden and as a cut flower.

Easy to grow, prolific bloomer. Deadheading will prevent seeding, but birds are crazy about the seeds, and the seedheads are attractive in the winter, especially in the snow. If removing them, leave the foliage at the base of the plant to overwinter.

So far not a prolific bloomer in it's first year. Different shaped flower.
