Cleome plants are very heat and sun tolerant. Even though it is an annual flowering plant, it is also a liberal self-sower, dropping its own flower seeds. Due to this fact, it should reappear the following spring.
Sow Cleome Flower seeds indoors in late winter for transplanting outdoors after the danger of frost. Or for areas with a long growing season, sow the flower seeds directly in the garden after the danger of frost has passed and the soil temperature has warmed.
Do not cover the flower seeds but firmly press them into the soil. Keep the Cleome seeds moist until germination occurs and then water regularly to provide a great start for this prolific bloomer.
