Flower Specifications
Dame's Rocket is a showy, short-lived perennial with large, loose clusters of fragrant flowers that bloom from May to August on flowering stalks 24 - 48 inches in height. The heavenly clove-like scent will attract lots of bees, butterflies and birds. This member of the mustard family has flowers with four petals. Many flower seeds are produced in the flower clusters.
The leaves are oblong, sharply toothed, and alternately arranged. Leaves decrease in size as they ascend the stem. This species is often confused with garden phlox (Phlox paniculata). Unlike Dame's Rocket, the phlox species have opposite leaves that are not toothed, and flowers with five petals, not four.
