Appearance
Height is 2–3 ft with a spread of 1.0 to 1.5 ft. The species needs full sun and medium water. It is easy to grow. Spent flowers should be removed to encourage additional bloom and/or to prevent any unwanted self-seeding. This plant is in part distinguished from black-eyed susan by having a more profuse bloom of smaller flowers that usually have fewer rays per flowerhead. The basal leaves are often trifoliate.References:
