Rudbeckia
( rud - BEK - ee - uh )
At-A-Glance InformationThis genus of perennial and biennial flowering plants needs full sun and moderate to regular water. Their flowers will attract birds, butterflies, and other beneficial insects to your garden, making them a great choice for gardeners who love biodiversity. They have large, yellow flowers, and are easy to grow. Rudbeckia makes great cut flowers, and cutting them for this purpose will encourage more blooms to form. Blooms appear in summer and fall.
