Plug Connection
Rudbeckia hirta
Black-eyed Susan has come a long way! These 3 varieties may hardly be recognized by your customers as the roadside wildflower they used to be.
Sahara is a favorite with variable brown, red, gold and tan shades with some semi-double to double flowers. Irish Eyes is big and tall with golden petals and a bright green center. ChimChiminee has the full range from gold to rust with double flowers of petals that never unroll, giving them a slight porcupine effect. Cherry Brandy is a bit short but certainly worth growing with its deep burgundy petals and dark center. Rudbeckia hirta is quite adaptable. Plant anytime, starting 6 weeks before frost. They enjoy a cold establishment period and may perennialize in some settings.
The range of colors and degree of doubleness will vary within each variety. Rudbeckia is not the most stable, genetically speaking. Photos are provided as a guide not a guarantee.
Grown in a 288 cell tray billed as 285.
Order 6 or more weeks in advance of desired ship date.

| Bailey's Notes |
Rudbeckia hirta can perennialize in some locations, but it generally treated as an annual. They need long days to flower. When planted under short days they will grow roots and leaves and then flower as the days increase in length. Best stem length will come from plants that are established under short days and then allowed to flower as summer progresses.
