     Great Blue Lobelia's intense, blue blooms arise on spikes in late summer.  Hummingbirds love this plant, as do butterflies, beetles and native bees.  It is also a moth larval host.


     This beautiful plant will add a spray of dark blue to a moist garden.  It self-seeds, and new plants form semi-evergreen rosettes that make a nice ground cover.
