Ageratum, or Foss Flower, provides a pretty splash of pom-pom shaped color for your garden or containers. Butterflies are attracted to them, and they're great flowers for cutting. If you're looking for a true blue in the garden, blue Ageratum is a great choice. This annual flowers best in sun, but can stand a little shade. Blooms in spring, summer, and late summer.
