Blue Mistflower

A relative of Gregg’s Mistflower (sun loving), Blue Mistflower prefers a shadier spot, with protection from harsh afternoon sun. It makes a good groundcover in morning sun and shady locations, and because it spreads via rhizome it can create a thick patch that can be mowed down to keep the plant short (under 12”). Tiny blue flowers can last for 5 months in midsummer into fall. In morning sun it can reach 3 feet tall. Also called Blue Boneset and Wild Ageratum.
