Echinacea purpurea 'Twilight' revert to normal purple coneflower?
I bought a 'Twilight' last summer when it was on sale at the local nursery. At the time, it had pretty sparse basal leaves but bloomed well that fall. This year it seems that it no longer blooms like 'Twilight' with its distinctive color and form. It looks like a normal purple coneflower but with droopy flower petals. Is this possible?
