Days to Germination:10-15 days
Coleus blumei. Prized for their exotic and colorful foliage, Coleus should be started indoors at least 6 to 8 weeks before transplanting outside after all danger of frost has passed. Sow seeds on top of the soil mix, leaving the seeds uncovered but pressed firmly onto the soil surface, as light is needed for germination. Provide even, lukewarm moisture and strong light during germination. Prepare a garden bed in dappled sunlight or shade, with rich, welldraining soil. Harden the plants off by gradually acclimating them to outside conditions over 1 to 2 weeks. Thin or carefully transplant the seedlings into the garden, planting them 8" to 12" apart. To encourage branching, pinch back the young plants once 8" tall, and flowers as they form. All the rage in Victorian gardens, Coleus are perfect companions in window boxes, whimsical containers, urns and in tranquil shade gardens. Height: 10" to 20".
