Lobelia siphilitica
blue lobelia, great lobelia
Great blue lobelia's flowers make great landing pads for our native bumblebees, never far away when this species is blooming. A versatile plant, this long-flowering summer perennial can stand moist to borderline-dry soils, and tolerates partial shade very well.
