Gregg Mistflower
Conoclinium dissectum
Gregg Mistflower is a low, spreading herbaceous perennial in the aster family, grown for its powder-blue, ageratum-like flower clusters that open from midsummer into fall. It spreads by rhizome into a loose groundcover and tolerates dry, gravelly, well-drained ground in full sun to partial shade. The long bloom period draws large numbers of butterflies, especially queens and monarchs, making it a strong late-season nectar source.
