Annual Lobelia Plant

The lobelia plant is an attractive annual herb with many varieties.
Annual lobelia will grow nearly anywhere. Lobelia seeds can be sown directly in the garden or indoors for later transplanting. These plants typically require an area with full sun but will tolerate partial shade. They also prefer moist, rich soil. Start indoors about 10 to 12 weeks prior to the last frost in your region. Spread the tiny seeds just on top of the soil and water thoroughly. Place them in a warm, well-lit area. The seedlings should pop up within a week or two, at which time you can begin thinning them out. After all danger of frost is gone and the plants are at least 2 to 3 inches tall, transplant them to the garden — spacing about 4 to 6 inches apart.
