Days to Germination:14-21 days
Lobelia erinus. Start transplants indoors 10 to 12 weeks before setting out after the last frost date. Sow seeds on top of soil mix, leaving the seeds uncovered but pressed firmly onto the surface, as light aids germination. Provide even moisture of the soil and strong light. When seedlings are 4" tall, harden them off by gradually acclimating them to the outdoors for 1 to 2 weeks. Carefully transplant out into well-draining, loamy soil in full to filtered sunlight spaced 6" apart. Known as an edging Lobelia, perfect for abundant pathside borders, it may be planted 3" apart in cascading hanging baskets and lush window boxes. Shade-tolerant, it offers plump 8" trails of little, 5-petalled, 1⁄2" flowers with thin, somewhat sparse, foliage. Summer flowering. Height: 8".
