Solenostemon scutellarioides: Classic Coleus for Vibrant Foliage Displays

Coleus (Solenostemon scutellarioides), syn. Coleus blumei var. verschaffeltii, are tender tropical perennials grown as annuals outside Zone 11. Famous since Victorian times, they offer endless leaf color combinations—chartreuse, rust red, cream, purple-black—often mixed in irregular patterns. The darker the red in the leaf, the more sun the plant tolerates. Summer brings blue to white nettle-like flowers, but they detract from the foliage show; pinch them off.

Growing Conditions

Grow in warm, well-drained soil; avoid overly dry conditions. Full sun yields the most vivid colors; half-day sun gives softer hues. Too much sun causes wilting; too much shade causes legginess. Overwinter indoors where not hardy. Propagate by surface-sowing seed at 72–75°F in early spring, or root softwood cuttings from late spring to autumn. Watch for mealybugs, scale, and whiteflies under glass.
