Lobelia siphilitica

Lobelia siphilitica is a native perennial that forms flower spikes of beautiful blue, tubular flowers which bloom from July-October. This would be perfect for a shadier rain garden that has consistently moist soils. Often found in wet woodlands, meadows or along stream banks. The flowers attract long tongued pollinators, primarily bumblebees, as well as hummingbirds. Its close relatives are the Cardinal Flower and Lobelia inflata.
