(Bidens) Add a spot of hot orange to your garden with Bidens Campfire® Flame. The large 1 inch blooms have a deep yellow eye and bright orange petals, Bidens Campfire® Flame flowers from early summer until Fall. Creating a 8-14 inch dense mound, Campfire® Flame has a more refined habit and mildew resistance. The more heat you give them the happier they are. Bidens are heat and drought tolerant, and prefer to be grown in full sun to part shade locations. These self cleaning annuals are a great selection for combination planters, and in the landscape, enjoy the continuous blooms all summer long.
