It is an annual growing to a height of 150 cm (60 in), with spirally arranged leaves. It has a height of 90 cm (35 in) to 180 cm (71 in). The leaves are palmately compound, with five or seven leaflets, the leaflets up to 12 cm (5 in) long and 4 cm (2 in) broad and the leaf petiole up to 15 cm (6 in) long. Its maximum crown width ranges from 30 cm (12 in) to 60 cm (24 in). The plant is sometimes mistakenly identified as cannabis due to its leaves and general growth shape. The flowers are purple, pink, or white, with four petals and six long stamens. The fruit is a capsule up to 15 cm long and 3 mm (0.1 in) broad, containing several seeds. Flowering lasts from late spring to early fall.[2]
The scented blooms are sometimes compared to citronella.[6]
Cleome houtteana is commonly cultivated in temperate regions as a half-hardy annual. Numerous cultivars have been selected for flower color and other attributes. The "Queen" series includes the cultivars 'Violet Queen', 'Rose Queen', and 'White Queen'. The cultivar 'Helen Campbell' has gained the Royal Horticultural Society's Award of Garden Merit[7] (confirmed 2017).[8] Plants in cultivation have at times been misidentified as Cleome arborea, C. pungens or C. spinosa.[3]
