Description

Botanical Interests' Cambridge Blue Lobelia Seeds showcase delicate, light blue flowers that create a striking contrast against their low-growing, pale green foliage. Perfect for borders, hanging baskets, containers, or window boxes, these flowers bloom profusely from spring to fall and attract beneficial insects and pollinators. In mild climates, lobelia may even continue blooming through the winter. Grown primarily as an annual, it’s a great option for gardeners looking for continuous color throughout the season. The plant forms a mound 4″–6″ tall and may reseed under ideal growing conditions, making it a low-maintenance favorite for gardeners.

3,000 seeds.
