Cleome Fast Facts

Overview

Cleome, popularly called spiderflower, is an exotic, dramatic annual that provides a colorful addition to the flowerbed or border. Cleome is a vigorous, hardy, pest-free plant that has earned its reputation as a reliable cottage-garden staple.

Identification

Cleomes produce upright stems bearing clusters of white, pink or lavender flowers from midsummer until frost. Plant heights range from 3 to 6 feet, with a spread of 2 to 3 feet. They are best placed at the back of a border.

Planting Needs

Spiderflowers are fast growers that thrive in a sunny location, protected from wind. An undemanding annual, cleome should be planted in well-draining soil, as damp, heavy soil may contribute to root rot.

Considerations

Cleome is a sturdy annual, rarely bothered by insects or disease. They appreciate a good watering during prolonged dry weather. Fertilize periodically.

Care

Cleomes are prolific self-seeders. There is no need to deadhead fading flowers, but do thin seedlings on a regular basis.

Benefits

Cleomes get their nickname from their long, airy stamens. Their graceful, showy flowers make them attractive cutting flowers.

Cautions

Cleome stems are spiny and somewhat sticky, so be careful when handling. Additionally, the flowers have a distinct fragrance, which some people find unpleasant.
