 Great blue lobelia is a cool-season annual that grows to about three feet tall. It is a perennial but doesn't live very long. It blooms in late summer and early fall. The flowers are blue, and the leaves help protect them from frost. When planting, make sure to dig the hole deep enough so that the root ball is covered by at least two inches of soil. Plant the lobelia at least 24 inches away from other plants, fences, or building structures so that it has plenty of room to grow and bloom.

 Great blue lobelia is a perennial plant, but it's not hardy in all parts of the country. In areas with mild winters, blue lobelia can grow annually. In colder regions, it should be developed as a perennial. In warmer areas, the plant can survive without protection from frost. It can be grown in full sun or partial shade, and it will do well in most soils except sandy ones. If you plan to develop it annually, you must start your seeds indoors at least two weeks before planting outside.
