Floss Flower (Ageratum houstonianum) is an attractive annual with fluffy blue flowers that bloom from late spring to frost. A native to Central America and Mexico, it has become invasive in some areas. Does well in full sun with some afternoon shade in hot summer climates and likes organically rich soil. Deadheading is not necessary.
