Vulcan Coleus: Crimson Puckered Leaves with Lemon-Yellow Edges

Vulcan Coleus

Solenostemon scutellarioides ‘Vulcan’ (sol-en-oh-STEM-on skoot-el-lar-ee-OY-deez) is a 26-inch-tall upright cultivar with a complex, dramatic color scheme. Its crimped, puckered leaves are deep crimson with an undercurrent of reddish rose, brushed with black that heightens the richness. A defining edge of lemon yellow separates each leaf, preventing the colors from blurring into a solid mass. A single plant can carry a garden scene for an entire season—use it to brighten a post-spring lull or pair with late-season stars like asters and mums.

Key Features

• Foliage: Large, textured, puckered leaves in crimson, rose, black, and lemon yellow.
• Habit: Upright, 26 inches tall, strong presence.
• Seasonal Bridge: Excellent for filling gaps between spring and fall bloomers.

Growing Conditions

Provide warm, well-drained soil and regular moisture. Grow in full sun to medium shade; colors are most vivid in full sun, softer in half-day sun. Pinch flower stems to maintain shape and foliar focus.

Propagation

Sow seeds on the soil surface at 72–75°F in early spring. Root softwood cuttings from late spring to autumn.

Potential Issues

Mealybugs, scale, and whiteflies may occur under glass. No serious outdoor pests or diseases.
