Colorful lobelias are an excellent choice for garden design around streams and ponds, anywhere the soil is constantly moist. In fact, Lobelia likes absolute humidity conditions, making it one of the best options for swampy botanical gardens.
Lobelia is a genus of annual or perennial flowering plants with 415 known species[1] in the Campanulaceae (bellflower) family, native to almost all temperate and warm regions of the world. It is known by many other names, including edging Lobelia, cardinal flower, asthma weed, and vomit weed.
