Why Choose Cardinal Flower Varieties for Edging and Ground Cover?

Growing Tips for Cardinal Flower Varieties
Most cardinal flower varieties prefer moist, well-drained soils and partial shade. They thrive in areas with consistent moisture, such as near ponds or in rain gardens. Deadheading spent flowers encourages prolonged blooming, and dividing clumps every few years helps maintain plant health and vigor.
Plant your selected varieties in early spring or fall for best results. Mulching around the plants helps retain soil moisture and suppress weeds. With proper care, these varieties will provide vibrant color and attract hummingbirds season after season.
