I won't buy them unless I can find a gallon pot in bloom. If a plant is too weak to grow normally, I avoid them now. Often times if you pinch the blooms off they still don't return after winter..,Then you never got to see them bloom. The Sombrero series seems to be better in many aspects, including the branching/fullness of the plant. Terra Nova's Echinaceas have poor branching. I don't buy their Echinaceas anymore. I hear they are improving, but not up to their competition just yet.
