500 Blue Lobelia Seeds Heirloom Native Wildflower Pollinator Garden

Lobelia erinus, commonly called blue lobelia, is a charming heirloom annual wildflower prized for its dense spikes of small, vivid blue blooms. Its compact, trailing habit and long flowering window make it a favorite for pollinator gardens, borders, and container plantings, where it delivers steady color from early summer into fall with minimal fuss.

These seeds are well suited to edging beds, filling hanging baskets, and naturalizing in meadow or cottage-style plantings. The blooms attract bees and butterflies, and the plants perform best in cool, consistently moist conditions with some afternoon shade in hotter regions. Start seeds indoors before the last frost for the earliest blooms, or sow directly in prepared ground once soils have warmed. Lightly press seed into the surface, as germination benefits from light exposure.
