What kind of soil does Commelina need?
This plant does best in partial shade, in moist to mesic conditions, with fertile soil that is loamy or slightly sandy. Asiatic dayflower tolerates full sun and light shade. It is a weedy, sprawling plant that often roots at the joints of stems. The root system is fibrous, and the plant can root and form new plants vegetatively. At favorable sites, the Asiatic dayflower forms colonies that can exclude other species of plants, and it is considered invasive by several states (but not NC). Asiatic Dayflower can spread aggressively and become a pest.
