Summary

Lobelia glandulosa, commonly known as Glade Lobelia, is a deciduous perennial herb native to wetlands and moist areas in the Southeastern United States, particularly in Florida. It typically grows to a height and width of 1-3 feet (0.3-0.9 meters). This species forms clumps of upright stems with narrow, lance-shaped leaves and produces striking blue to violet flowers with white centers from late summer to fall, which are highly attractive to pollinators such as butterflies and hummingbirds.

Glade Lobelia is valued for its vibrant floral display and its ability to thrive in wet conditions, making it suitable for rain gardens, water edges, and bog gardens. It is also used in borders for its vertical accent and color. In cultivation, it prefers consistently moist to wet soils and can tolerate a range of drainage conditions. It is adaptable to full sun or part shade, but flower production is best with more light. While generally low-maintenance, it can be susceptible to root rot if drainage is poor. There are no widely known popular cultivars, but the species itself is a standout in appropriate settings. It is not typically invasive but should be monitored to ensure it does not spread beyond its desired area.CC BY-SA 4.0
