Plectranthus

Lamiaceae (Labiatae)
Evergreen, Ground covers, Perennials, Shrubs

Close relatives of coleus; native to many tropical regions of the world. They have square stems, opposite pairs of fleshy, tooth-edged or scalloped leaves, and whorls of tubular, two-lipped blossoms. Some are highly aromatic, used as seasonings or home remedies. Others are grown for their attractive foliage, yet others for their striking floral displays. Some are good bedding plants for summer color; some make dense, weed-suppressing groundcovers for frost-protected areas. Several are trailing plants that drape gracefully from hanging baskets or wall pots. All are superb in containers, either alone or in combination with other plants.

Easy to grow. Stems take root wherever they touch the ground. Cuttings root quickly in soil or water. Remove flower spikes after they fade. Pinch all types to induce branching; discard old plants when they become leggy or too woody and start new ones.
