Asters are an excellent source of nectar for butterflies in late summer and fall. The flower color of native species and their cultivars ranges from shades of purple and pink, even red, to white. Native species can be found growing in a wide range of soil and moisture conditions. While most asters prefer full sun (6+ hours), some species do well in partial (~4 hours sun) to full shade. Height can range from 1' - 6'. Host plant for crescentspot butterflies.
