Gaillardia pluchella, simply known as gaillardia, is a very cold tolerant native plant. As such, it can be started from seeds, or planted as young seedlings in winter without concern for cold weather damage. In natural stands, it most begins to germinate in February and again in August. Plants from seeds germinated in February usually do not persist beyond May of the same year. By October, even late germinated or set plants are no longer aesthetically pleasing and are usually removed by the gardener at that time. The plant is highly drought tolerant and so salt tolerant it is seen growing on South Florida beaches.
