‘Purple Heart’ is a trailing, tender perennial with purple stems and violet-purple leaves that produces pink flowers in summer. This plant is mainly grown for its foliage (leaves can reach 7 inches in length); best color is achieved in bright sunlight and a dry, cramped root zone. It is excellent as a groundcover or in containers or hanging baskets. It grows 8-12 inches tall and 16 inches wide.
Grow purple heart in full sun for best color development; plants growing in shade tend more to green than purple. Pinch the plants to promote more compact growth. Plants are drought tolerant and thrive on neglect, but also tolerate frequent watering. Fertilize monthly when actively growing. Cut plants back after flowering to prevent them from getting spindly. If grown in containers to hold indoors over the winter or as houseplants, reduce watering during the winter and don’t fertilize until new growth starts in spring.
