100 Great Blue Lobelia Seeds Lobelia siphilitica Wetland Wildflower Rain Garden

Great Blue Lobelia is a clump-forming wetland wildflower native to moist meadows and stream banks, prized for its tall spikes of soft blue blossoms that appear from midsummer into early autumn. Its upright habit and reliable bloom make it a striking addition to rain gardens, pond margins, and damp borders.
The nectar-rich flowers draw bees, butterflies, and hummingbirds through the season, while the sturdy stems hold up well in mixed plantings. It pairs naturally with other moisture-loving perennials and works well massed along water features or in low-lying areas of the landscape.
