If you want instant, vibrant drama in a shady spot, Common Coleus is your answer. Also known as Painted Nettle or Flame Nettle, this soft, fast-growing evergreen perennial is grown entirely for its spectacularly coloured leaves. It has distinctive, four-sided, semi-succulent stems clothed in opposite pairs of large, velvety, ovate leaves with serrated or scalloped edges. The colour combinations are almost endless—greens, yellows, pinks, reds, maroons, deep purples, and even near-black, often in intricate patterns. In summer, small spikes of tubular blue to lavender flowers appear; many gardeners pinch these out to keep the focus on the foliage, though bees love them.
Native to tropical and subtropical Southeast Asia, Common Coleus has found a perfect home in the Western Cape’s warm temperate gardens, often grown as a colourful summer annual. It thrives in partial shade to bright, indirect light—leaf colour is brightest in filtered sunlight. Protect it from harsh afternoon sun, which can scorch the leaves. It prefers humus-rich, well-drained soil kept consistently moist. It’s sensitive to frost, so treat it as an annual in colder inland valleys, though it may survive mild coastal winters in a very sheltered spot. Reaching 30–60cm tall and wide, it’s perfect for shady borders, mixed containers, hanging baskets, or as a striking indoor plant.
Key Features:
- Spectacular multi-coloured foliage in greens, yellows, pinks, reds, and purples
- Thrives in partial shade—perfect for brightening dark corners
- Fast-growing and bushy, filling spaces in a single season
- Easy to propagate from cuttings
Gardening Note: Plant in well-drained, fertile soil in partial shade to bright, indirect light for the most vivid colour. Water regularly to keep the soil consistently moist but not waterlogged. Pinch back growing tips regularly to encourage a bushier habit and prevent legginess. Remove flower spikes to keep energy focused on the leaves. Protect from frost; in colder areas, grow in containers that can be moved indoors for winter.
