Plant Encyclopedia Blue Lobelia

Must Know Plant Care Tips: Blue lobelia will bloom its best in cooler temperatures, like fall and spring. In the heat of summer, it will usually stop flowering. At this time, shear it back and it will likely bloom again in the fall when temperatures cool down. It will grow in a variety of soils, but prefers sandy, clay, or loam soil.

Plant Problem Solver: Blue lobelia looks beautiful in hanging baskets, near a natural water source, or as a ground cover. If you need something easy to plant, this is a great bet. To start them indoors, just spread the seeds on top of the soil and water them in well. Within a week or two, you’ll have seedlings. Blue lobelia is also wonderful for planting on slopes or to control erosion. Once established, it’s a low-maintenance plant. Keep the soil moist as it is not drought tolerant.

Pretty Pairings: Blue lobelia is a wonderful feature for an english garden. It will look lovely planted near phlox, delphiniums, hollyhocks, daisies, foxglove, lavender, and lady’s mantle.
