Cleome is an annual flowering plant known for its tall, upright growth and distinctive blooms with long, protruding stamens. It adapts well to warm climates and performs reliably in garden beds, borders, and open landscapes with full sunlight. The plant tolerates a range of soil conditions as long as drainage is adequate and is often used for adding height and structure to seasonal plantings. Once established, it shows moderate tolerance to dry conditions and continues blooming through the warm growing season.
