Lobelia plants are vibrant flowering annuals and perennials known for their rich blue, purple, red, and white blooms that add bright color to garden beds, containers, and borders. With compact growth and abundant flowers, lobelia works well in mixed plantings, hanging baskets, and edging plantings where bold color impact is desired. These cheerful blooms thrive in moist, well-drained soil and full sun to partial shade, making them versatile accents in a variety of landscape settings.
