Lobelia siphilitica
Lobelia siphilitica | great blue lobelia
Great blue lobelia is a short-lived perennial that often persists in gardens by means of volunteer offspring. Naturally occurring in wet soils, this species prefers consistent moisture and tolerates partial shade. It is prized for its spikes of brilliant blue flowers that attract a diversity of pollinators and hummingbirds. The flower color can range from a rich lavender to a vibrant dark blue, but set amongst a landscape that is often laden with many yellow-flowered summer bloomers, great blue lobelia is always a welcome contrast.
