How to Grow Floss Flower (Ageratum Houstonianum)

One of the most popular of all annual flowers, floss flower is an excellent choice for growing along the edges of flower beds, where its short stature and small puffball flowers can be appreciated. It comes in blue, pink and white and generally grows about a foot high, though some dwarf varieties are available.
