plant sale text: This is the earliest of the native Black-eyed-Susan species to bloom. Its basal rosettes of fuzzy leaves are crowned by bright yellow flowers in early summer. Native Americans considered this plant an herb and used it for treating sores. The root of this native species can be used to produce a brown dye. Black-eyed-Susans are great for perennial borders, meadow gardens, or containers. If you wish, you can let them reseed so that you have more plants next year. Black-eyed-Susans make a good cut flower.
