Appearance and Use:

Annual lobelias shine when used in containers and basket culture, for edging and bedding material, and when used in the flower borders. Also readily grown as house and conservatory plants. Habit ranges from upright to spreading and flowers are a mix of colors from blue, red, pink, and white. Lobelia erinus, Edging Lobelia, a trailing annual to 4-8 inches tall, is native to South Africa.
