A native lobelia with showy red flowers- favored by swallowtail butterflies and hummingbirds! Adaptable to soil type, but requires wetter than average conditions. Plants grow happily in shallow water, and are absolute stunners for water edges, wetlands, and moist ditches!

Notable Wildlife Interactions: Flowers attract hummingbirds, butterflies- particularly swallowtails- bees, and flies. Hosts the pink-washed looper moth. Rarely browsed.
