Tall and quite unusual during several stages of bloom development. I got the full 'double decks' during the second year.

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.

a proven winner in my clay and sandy soil. The butterflies and hummingbirds are always at it

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.
