Foliage Plant
Rainbow Blend Coleus is a striking cultivar of Plectranthus scutellarioides that transforms partial shade into a living canvas of vibrant, multicolored foliage. Growing 12 to 36 inches tall with a spread of 6 to 18 inches, this member of the Lamiaceae family thrives as both a seasonal annual and year-round houseplant, offering gardeners endless possibilities for creating dramatic displays in containers, borders, or indoor spaces. The variety's appeal lies entirely in its spectacular leaf patterns and colors, a true celebration of botanical diversity that deserves a prominent spot where afternoon light can showcase its chromatic range.

What sets Rainbow Blend apart is its sheer chromatic exuberance. Each plant in a planting produces leaves with distinct color combinations and patterns, creating a naturally diverse composition from a single seed packet. This isn't a uniform variety engineered for sameness; instead, it celebrates botanical variation, making every seedling a small surprise. The foliage is the main attraction, with leaves that catch even dappled light beautifully and provide season-long color without relying on flowers. It's an excellent choice for gardeners who want drama and depth in shaded corners where many plants struggle.
Rainbow Blend Coleus is grown primarily for its ornamental foliage, prized in container gardens, mixed borders, and indoor houseplant collections. The vibrant, multicolored leaves make it a standout choice for creating visual interest in partially shaded areas where flowering plants often disappoint. It works beautifully in mixed containers where its varied leaf patterns complement solid-colored annuals and perennials, and it's equally at home as a solo specimen plant bringing year-round color to a sunroom or bright interior space.
Start seeds indoors 6 to 8 weeks before your average last frost date, or any time of year when growing as a houseplant. Maintain a soil temperature of 70 to 80 degrees Fahrenheit for germination. Press seeds into the soil surface without covering them, as they benefit from light exposure. Provide bright, indirect light once seedlings emerge and maintain consistently moist (not waterlogged) soil.
Transplant seedlings outdoors 1 to 2 weeks after your average last frost date, once soil has warmed and all danger of frost has passed. Space plants 6 to 12 inches apart to allow for their mature spread of 6 to 18 inches. Harden off seedlings gradually by exposing them to outdoor conditions over 7 to 10 days before final planting.
Direct sowing outdoors is not recommended; indoor starting followed by transplanting produces stronger, more robust plants.
Pinch back the growing tips of Rainbow Blend regularly throughout the growing season to encourage branching and create a fuller, more densely foliated plant. This practice is especially valuable in the early stages of growth and can be repeated monthly to maintain a compact, visually striking shape. Remove any leggy or sparse growth to direct the plant's energy toward producing the colorful foliage that makes this variety so appealing.
