In cooler regions, Lobelia erinus is commonly planted as a warm-season annual rather than relied on as a hardy perennial. ## Growing Conditions Grow in full sun or partial shade. Species guidance from [North Carolina Extension](https://plants.ces.ncsu.edu/plants/lobelia-erinus/) recommends organically rich, moist, well-drained soil and consistent moisture. In hot climates or during hot weather, partial shade helps reduce stress; good drainage prevents waterlogged roots. The upright selection should be spaced so neighboring plants do not crowd its flowering stems. ## Maintenance Water regularly enough to keep the soil evenly moist, especially in containers and during warm spells. Do not let the root zone dry completely, but avoid standing water. If flowering slows after the first flush, a light shear and continued watering can encourage renewed growth; remove spent stems to keep the planting tidy.
