Cleomes aren't the most popular annuals sold at nurseries, and it might be because they look rather weedy as young seedlings. Cleomes usually do not start blooming until they are well established in the garden. Though they can be planted in early spring, many gardeners opt for a late fall seed sowing directly in garden soil.
