How to Germinate Early Ostrich Plume Aster

Ostrich plume aster is a flowering annual plant that comes in a variety of colors. It is one of the earliest blooming asters, and you can get a head start on the season even earlier by germinating the seeds indoors. A propagator, which is a heated seed starting tray with a plastic cover, will allow you to germinate the seeds in your windowsill. They are available at gardening centers. Germinate early ostrich plume asters as early as March.
