Gardeners' Notes:

I planted five Echinacea varieties just this late spring (about six weeks ago). The list includes the Double Decker, Green Jewel, Double Scoop Bubblegum, Kims knee high and the Pow Wow. All have been well watered and in a good mix of well-drained soil receiving full sun with harsh afternoons. All are happy and healthy, but my best performers by far are the bubblegum and green jewel producing multiple blooms with no end in sight as I see buds way down the line. The bubblegum has a very unique shape as well as a beautiful color, the green jewel is interesting because there just are not that many green blooms around (other than some of my hydrangeas).

I purchased two of these as healthy-looking mature plants and planted them in a sunny spot in mid-May of this year. I got continuous blooms, but the plant did not thrive the way I had expected... there were fewer blooms, and the foliage ultimately withered and dried up, despite other similar plants in the same spot thriving. But, I never expect to get great performance the first year that I plant a mature perennial. I am happy to report that this plant has already begun to spread, and the new growth looks happy and healthy. The original plant seems to have grown a whole "new" plant to its side - I have new, mature leaves, and blooms just opening now, in early October, on the edge of zones 4b and 5a. I also see smaller seedlings coming up around the plant. I fully expect that next spr... read more

Nice color, another prolific bloomer. Really short and a nice contrast to the taller echinaceas.

First year growing, but spreading quickly. Multiple flowers. Very pretty plant. A little taller than anticipated.

I just bought one of these at Lowe's today, and it looks extremely healthy and what a wonderful deep color!
