When thinking of fall bloomers for your garden, everyone's usual go-to is the mum, but don’t rule out the gorgeous asters sitting next to the mums. There are 180 species of aster, many of which are native to Illinois. New England aster (Symphyotrichum novae-angliae) and aromatic aster (Symphyotrichum oblongifolium) are two easy-to-find favorites.
A few years back, Illinois gardeners learned that there is more to monarch decline than a lack of milkweed to support larvae, or habitat destruction in their overwintering home. Another contributing factor is a lack of floral resources for adult monarch butterflies to make the journey in the fall. University of Illinois Extension pushed a campaign to plant more of these fall bloomers.
