Lobelia siphilitica
Lobelia siphilitica has beautiful blue spikes popular with hummingbirds and butterflies.
Lobelia siphilitica was once used to treat syphilis now it is used to grace gardens. The beautiful blue spikes of great blue lobelia do remarkably well without staking in sun to part shade. The blue is stunning against its pale green leaves and is useful to create a delphinium-like effect in shadier parts of the garden. Enjoys a moist soil but will do well in average sites as well. Native to much of eastern North America.
