Lobelia siphilitica has a dark green basal rosette of low-growing leaves that produces a tall thick stem with whorled leaves topped with a spike of flowers. The flowers are brilliant blue, clustered at the top of the stalk and have prominent, drooping lower petals. Prefers moist rich soil and filtered light, but can handle full sun if watered frequently. Good bumblebee forage plant.
