Flat-Topped Aster (Doellingeria umbellata)

from $3.50

Flat-topped Aster (aka Parasol Whitetop), formerly Aster umbellatus is an attractive plant that is host to the Pearl Crescent, Silvery Checkerspot, Harris Checkerspot, and 15 other butterflies and moths in our area (nwf.org). The nectar and pollen of the flowers attract many different native bees, including 4 specialist bees (Illinoiswildflower.info). This plant is also visited by many herbivores, so it may need to be protected in its early years. Keep in mind that this is a rhizomatous plant, meaning it spreads by underground rhizomes as well as by seed, so it can be vigorous, so be mindful of where you plant it.
