Ageratum

Ageratum is such a little workhorse that nearly every garden should have some. This annual is an easy-to-grow, old-fashioned favorite that produces a steady show of colorful powder-pufflike flowers from late spring through frost. It's also rarely bothered by pests, so you count on it to look good. Plus, it provides some of the truest blues you can find in flowers -- a rare thing.

Plant in spring after all danger of frost has passed. Plant in groups of a dozen or more for best show. Deadhead and fertilize regularly for best blooms.
