Star Cluster has now been here 3 summers and 2 horrible winters: one sopping wet winter and one polar vortex. It has been disease free and flowers well. However, it's very large. Grows about 24" tall, then flops over and grows up again. If I let it keep going, it would most likely cover a good 4' space. Good coreopsis if you can find the right spot in your garden.
