Black Eyed Susan
Rudbeckia hirta
Black-eyed Susan is a native prairie and meadow wildflower grown for its solitary daisy-like blooms of golden-yellow rays around a dark brown central cone, held on rough, hairy stems above a low rosette of basal leaves. It typically behaves as an annual, biennial or short-lived perennial, germinating in fall and flowering from summer into early autumn the following year. Bees, butterflies and seed-eating birds all use the plant, and it readily reseeds itself to hold a planting from year to year.
