The genus Cacalia includes a couple of dozen species of tender annuals from high altitudes in tropical Africa, India, and Polynesia. Rising from a rosette of leaves are stiff, slender stems topped by red, yellow, purple, or orange flowers that resemble tassels or tufts. Fluffy seedheads follow. Tassel flower attracts butterflies and is good in dried arrangements. Grow it in a border or annual bed.
