Tassel-flower is an annual or perennial plant in the Asteraceae (daisy) family native to Africa and Asia that has naturalized in North America and other tropical locations.  Upright stems are sparsely branched and dotted with red, pink or lavender flowers that resemble tassels, hence the common name. Some varieties can be quite weedy.

Stems of young plants are distinctively hairy, but they lose hairs with age. Seed heads are small (1/2 inch or less in diameter) dandelion-like globes of wind-dispersed seed. 

Plant in the front of the border in well-drained soil in full sun. They are tolerant of heat and humidity and the flowers are long-lasting and give an airy appearance. They can be grown in containers and make good cut flowers
