Great Blue Lobelia
The Great Blue Lobelia perennial plants are a must-have for old southern plantations and southern homeowners want them in their shade gardens. Its deep purple blooms and delicate foliage make it a showstopper for flower gardens and beds. The blooms climb the stalks of brilliant green foliage, making them a perfect pairing for the Cardinal flower, also in the Lobelia family.
Bloom Season, Uses and Care
Great Blue Lobelia blooms from mid-summer into early fall, typically July through September. It produces tall spikes of vivid blue to violet-blue flowers that attract pollinators like bees, butterflies, and hummingbirds. Deadheading spent blooms may encourage a longer flowering period, though the plant often reseeds naturally.
Is Great Blue Lobelia a perennial?
Yes, this shade-perennial gem is hardy and thrives in many USDA zones, including 4–9. It dies back in winter and returns each spring. In the right conditions, it may self-seed and form beautiful naturalized colonies over time, without ever becoming invasive. It's a gentle lady at best and never intrudes.
Are Great Blue Lobelia Plants Deer Resistant?
Great Blue Lobelia (Lobelia siphilitica) is considered a hardy, deer-resistant plant. Its slightly bitter foliage and milky sap tend to make it less appealing to browsing animals. In areas with heavy deer pressure, young plants may still need temporary protection until established.
Can Great Blue Lobelia grow in wet soil?
Yes, this plant actually thrives in moist to wet soil conditions. It is an excellent perennial for rain gardens, low-lying areas, pond edges, and stream banks. Unlike many perennials that struggle with soggy roots, Great Blue Lobelia tolerates periodic flooding and consistently damp soil, making it ideal for difficult wet spots in the landscape.
