Alternanthera dentata. Start transplants indoors 6 to 8 weeks before the last frost date. Sow seeds on top of sterile starter mix, leaving the seeds uncovered but pressed firmly onto the soil surface, as light is needed for germination. Pamper with 65°-75°F temperatures, good air circulation, strong light and even moisture. Do not allow the seedlings to wilt or dry out. Once seedlings are large enough to handle, transplant them into larger, deeper pots for full root system development. After all danger of frost has passed, harden them off by gradually acclimating them to the outdoors over 7 to 10 days. Transplant out 12" apart in rich, moist, well-draining soil and full to partial sunlight. Prized for its mounding, shiny, deep purple foliage, Alternanthera is perfect in lush, combination containers. Summer leafing. Height: 16" to 20".
