If you’ve got a wet spot Great Blue Lobelia (also called the Blue Cardinal Flower) is the plant for you. A native of Pennsylvania Great Blue Lobelia attracts hummingbirds, butterflies and is an exceptional plant for bumble bees and other pollinators we count on. It’s happy in sun or part shade, grows 2′ to 3′ tall and provides blue blooms for late Spring.
It’s been around a long time. Iroquois used it for a cough medicine. The Meskwaki Native Americans ground up the roots for an anti-divorce remedy!
