The listing, Black-eyed Susan seeds-rudbeckia has ended.
Bright, sunny flowers that you'll only have to plant once, and will naturalize in your garden. Prefer a nice sunny spot but have grown and flowered in semi-shade for me, they just don't get as tall or do quite as well. In sun, they get about 2 feet tall. They are fuss-free and are nice to cut and bring in, too.
