Native Star (Starry Rosinflower Cultivar)
Rosinweed or Rosinflower, Silphium astericus, is a perennial that grows 2 to 3 ft. It produces a basal set of spaced leaves and bright yellow rayed flowers along an upright stalk. This is a great performing bloomer with flowers occurring through out the year in central Florida, with the spring, summer, and fall producing the heaviest blooming. Native Star is a new cultivar that has a more compact form (1 to 2 ft. tall) and is quicker to bloom. It looks best planted in groupings and tolerates average to moist soil with light shade to full sun. Cut stems back to the ground when they get thick and unattractive and the plant will reward you with nice foliage and bloom even heavier as a result. Rosinflower attract pollinators including butterflies.
