PLACEMENT & CULTIVATION
Cleome, also known as spider flower, requires very little care, making it ideal for back borders or areas that are difficult to maintain. Pinch once when 6" tall for bushier plants. It blooms for an extended period, with new buds forming and opening from the center as old petals fall. It is not only deer-resistant but also attracts a variety of pollinators, such as butterflies, hummingbirds, and hawk moths. It is an excellent cut flower; however, you should beware of the small thorns on the stems. Self-sows.
