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). Kims knee high also has multiple blooms, but I do not find them as color rich or as interesting as the others-they sort of sit on top of ... read more

This is deffinantly not my favorite coneflower. I bought this particular one at a local nursury about four years ago. It can take several years, as I found out, for this coneflower to double its decker. I only had a few straggly petals shooting up from the top last year. The plant itself has not even gotten much bigger. Maybe this summer it will finaly get that pritty double decker.

When bloom 1st opens, it looks a lot like a normal purple coneflower but with more (bottom) petals. The "top" petals don't begin to show up until a few days later. Bloom lasts for weeks.
