Lobelia
Lobelia is a compact and reliable annual to add some bright splashes of colour throughout the garden, even in the cool or shady spots. It flowers in nonstop waves of brilliant blues, pinks, purples, and white all summer long, and has pretty, dainty foliage. This plant is notable for having two different growth habits available, and gives wonderful versatility in the garden or containers. Compact varieties with an upright growth habit are a natural for edging or as fillers in flower beds. And the trailing varieties have a lush, spreading habit that are superb cascading out of containers, hanging baskets, and window boxes – or spilling over rockeries and retaining walls.
