Description:

Blackeyed Susan features daisy-like flowers with bright yellow-orange rays and brown center disks. The long bloom time lasts from June-September. This plant provides a nectar source for bees, and birds eat the ripe seeds. Blackeyed Susan is a host plant for butterfly and moth larvae (caterpillars), including Bordered Patch (Chlosyne lacinia) and Gorgone Checkerspot (Chlosyne gorgone). It does not tolerate prolonged, wet weather. Use Blackeyed Susan in your borders, beds, meadows, and naturalized areas. It also makes an excellent fresh-cut flower for bouquets.
