Aster Purple Dome is clump forming, which means it won’t spread and take over the garden, and its rounded growth habit stays neat and compact all season long. When the buds open to reveal a cushion-like blanket of plum-purple petals, you’ll also catch a glimpse of the flowers’ yellow centers. Those yellow centers are filled with nectar that’s enjoyed by many types of late-season pollinators.
Aster Purple Dome truly is carefree. The only regular maintenance that’s required is an annual “haircut”. Trim the entire plant down to the ground in the spring when you start to see new green growth emerge from the ground at the base of the plant. The old stems can be left to stand all winter long. The goldfinches and other birds enjoy eating the seeds, and the pollinators and other beneficial insects can take shelter in the dead stems through the winter.
