Coleus is a petite houseplant grown almost exclusively for its bold, colorful foliage. Coleus plants are native to Asia and Australia and boast a variety of pigmented leaves, in shades of green, pink, white, cream, yellow, maroon, and purple. The plant is often started from seed around a month and a half before the last frost. It will grow rather quickly, often reaching mature, robust size in six to nine months. Their unique appearance and ease of care make them a popular houseplant choice for both novice and experienced gardeners. For Instructions On How To Grow Coleus Coleus seeds need light and warmth to germinate. Sow seeds on moist soil or seed mix, pressing them gently into the soil without covering. Place the pots on a heating pad, seeding mat or comfortable windowsill and allow them to start and stay between 70oF and 75oF. If you want to grow Coleus outdoors, grow them as houseplants or in a greenhouse over the winter, hardening them and gradually acclimating them to outdoor temperatures. Transplant when the danger of frost has passed and nighttime temperatures are in the 50s and 60s.
