Coleus are a group of perennial plants native to tropical Asia and surrounding islands. They are noted for their bright, showy foliage and shade-loving habits. Coleus was a genus of flowering plants in the family Lamiaceae. In recent classifications, the genus is no longer recognized, and the formerly included species are instead placed in the genera Plectranthus and Solenostemon. The term “Coleus” is often used as a common name for species formerly place in the genus Coleus that are cultivated as ornamental plants. New name of Coleus blumei which is popular as a garden plant for its brightly colored foliage is Solenostemon scutellairoides.

Even though Flame Nettle plants are perennials in their native lands, most gardeners tend to use them as annuals. The flowers are insignificant and the main impact is from the gorgeous leaves that come in a huge selection of colors and patterns. Coleus are prized for their colorful foliage which may combine shades of green, yellow, pink, red and maroon. New introductions of this popular annual, have been selected for increased sun and heat tolerance.

Flame Nettles should be planted in a good quality potting mix, they do best when the soil stays evenly moist. Moisture is important, Coleus do like water and will wilt if the soil becomes too dry. Poorly drained soils and excessive watering will damage Flame Nettles.  Plants suffering from “wet feet” will be stunted, leaves will turn a muddy brown, and leaf margins will be scorched. Most Flame Nettles prefer bright, shady conditions with a bit of morning sun. Some varieties can tolerate more sun.

Coleus can reach 80-100 cm high and wide so a generous container is advised. Pinching growing shoots of young plants, encourage and maintain dense foliage. Flower spikes will appear in late summer. Propagation can be done by seeds or from cuttings. They root easily from stem cuttings at any season. Common Flame Nettles can also be grown from seeds. New hybrids generally flower little in the summer and require less maintenance than seed grown Coleus.

Flame Nettles are highly resistant to serious disease or insect problems when grown outdoors in properly prepared beds or containers. Some pests to watch for include mealy bug, aphids and whitefies.

Landscape Use: Coleus adapt well to container culture and are often used for a bright showy color at entryways or porches. Most Flame Nettles will grow best in part shade or dappled light. However, nowadays several sun tolerant cultivars are available.
