Has performed way past my expectations, since I took a while to get this young plant in the ground from it's 4-inch nursery pot...:(. Has tolerated extreme heat, drought, humidity...couldn't want a more carefree plant...can't wait to collect the seeds as it is parked near a white swan...maybe they crossed some pollen.

Extremely beautiful textbook echinacea, large blooms, and nice large dark green leaves, this plant is not very hardy however when it comes to high humidity heat where i live in rural NC, it seem to like higher elevations and dryer heat, the humidity just cooked the leaves on these this summer where i am; where it is very flat with swealtering humidity, even with plenty of water and a little shade, so again not an intense heat plant. mike.

Medium to tall bloomer, glowing intense carmine-red, very substantial flowers with horizontal petals on robust plants.
