Coleus are foliage plants in a wide selection of colors and patterns for the annual garden. They are easy to grow, stay vibrant in both sun and shade, and are tolerant of soil type. New colors and patterns are introduced regularly including dwarf varieties, trailing types and big-leaf, upright plants that grow to 3 1/2 feet tall.
At maturity, coleus produces tiny blue or white flowers on spikes but these are often pinched out to encourage more brilliantly colored leaves. Planted in spring, coleus provide season-long interest, dying back with the first frost. It's most often set out in the garden but can be grown indoors for several seasons. Coleus is toxic to dogs, cats and horses.1
