Rudbeckia hirta | black-eyed Susan

Rudbeckia hirta is a free-spirited species that generally blooms in its first year from seed and quickly brings cheerful color to any garden or meadow. Individual plants may behave as annuals, biennials, or short-lived perennials, but this species’ ability to reseed itself means that plants will gracefully move from one spot to another as the years pass. Possessing a fairly loose habit, this black-eyed Susan does best when grown interspersed among grasses or taller perennials for support, even in full sun.

LOCAL ECOTYPE

**Rudbeckia hirta seeds do not have dormancy—they will germinate quickly from a spring sowing. Seed packets contain at least 300 seeds.
