Black Eyed Susan ‘Macau’ 
Rudbeckia triloba 
 
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. Also serves as a filler or accent flower in bouquets. This rudbeckia tolerates most conditions, including drought, once established.
Short-lived perennial in Zones 3–9; typically flowers in the first year but may not bloom until second year if heavily crowded. Stems are reddish in color and have fine hairs.

Direct seed - Gently press seed into soil as soon as soil can be worked in early spring or fall.Pinching not required. Reseeds.
 
Harvesting;
When blooms are completely open.
 
 
Vase Life:
