Great Blue Lobelia

Great Blue Lobelia (Lobelia siphilitica) is a vibrant, moisture-loving native perennial that brings striking blue flowers and rich wildlife value to partially shaded garden spaces. This 32-plant pack is ideal for gardeners looking to add late-season color and pollinator support to rain gardens, woodland edges, or other consistently moist areas.

Blooming from late summer into early fall, Great Blue Lobelia produces upright spikes of deep blue flowers that are especially attractive to bumblebees, butterflies, and hummingbirds. Growing to 2–3 feet tall, it holds its own in layered plantings and pairs beautifully with other wet-loving natives like Cardinal Flower or Blue Flag Iris.

This plant thrives in moist to wet soils and performs best in part shade to filtered sun, making it a great solution for low spots, pond edges, or shaded borders where other plants may struggle.
