The color blue is pretty rare in nature, but the blue of lobelia (Lobelia erinus) is on the mark. This vibrant, low-growing annual brightens garden beds, borders, pots and even hanging baskets. It’s a favorite of gardeners and designers for its compact yet trailing habit, making it a star along walkways and mixed containers.
Native to southern Africa, the annual lobelia actually thrives in cooler climates, providing a much-need pop of blue from spring through early summer, and once again in fall. Lobelia thrives in full sun to partial shade and is a reliable bloomer with regular watering. As a USDA zone 2-10 seasonal annual, it’s best kept out of extreme heat. Give it cooler climates or partial shade and it’ll bloom happily.
