Lobelia siphilitica

Cardinal Flower - Big Blue

Big Blue Lobelia has clear blue flower spikes appearing in August and September, attracting hummingbirds, bumblebees and long-tounged bees. Given enough moisture, Lobelia siphilitica does well in full sun, even more than L. cardinalis. Very wet site tolerant, and naturalizes well from seed. Plants are indigenous to wet prairies, soggy meadows, edges of ponds, wet pastures.
