Rudbeckia triloba – Flower Seed

Densely branched, productive filler.
Profuse blooms of adorable, 1 1/2"– 2 1/2", bright yellow flowers with small, black/brown centers. Wiry, well-branched stems have few leaves, making this an excellent cut flower.

Short-lived perennial in Zones 3-9; typically flowers first year but may not bloom until second year if heavily crowded. Stems are reddish in color and have fine hairs. Leaves at the base of the plant are three-lobed, as indicated by the plant’s Latin name species: triloba. Also known as brown-eyed Susan and browneyed Susan. Ht. 48-60". Avg. 51,300 seeds/oz.
