Lobelia erinus aka Lobelia

Lobelia erinus, also known as edging lobelia, garden lobelia, or trailing lobelia, is a species of flowering plant in the bellflower family Campanulaceae, native to southern Africa. It is a trailing, tender perennial that is often grown as an annual. The plant features fine, spreading stems, tiny mid-green leaves, and an abundance of small, bright blue flowers from late spring until autumn. With thin basal leaves and deep blue, purple, or white flowers, Lobelia erinus is commonly used in window boxes or as an edging plant in gardens. It is native to South Africa and has been cultivated since the 1600s, resulting in numerous hybrids. There are two main varieties, a long trailing plant and a shorter, compact variety. The shorter edging lobelia rarely exceeds six inches in height, while the trailing habit lobelia can grow up to 12 inches with leggy growth. With its delicate stems and thin leaves, lobelia can spread up to a couple of feet, making it ideal for border edging. It blooms in the summer, producing an abundance of little flowers in various colors such as white, pink, purple, violet, or blue, each with a white eye.
