The cardinal flower, known scientifically as Lobelia cardinalis, is a delightful native perennial that thrives in the moist, cozy spots near streams, sloughs, springs, swamps, and low-wooded areas. This charming plant is a short-lived, clump-forming perennial that can grow to a height of 2-3 feet, showcasing large, vibrant red flowers on its unbranched, alternate-leafed stalks. The unique two-lipped tubular flowers feature three lobes on the lower lip and two lobes on the upper lip, adding to its beauty.
Among its varieties, ‘Queen Victoria’ stands out with her stunningly deep red flowers and rich dark burgundy foliage, making her a favorite among hummingbirds and butterflies alike.
Caring for this lovely plant is a breeze! It enjoys growing in full sun to partial shade and prefers rich, medium-to-wet soils. While it can adapt to brief flooding, keeping the ground consistently moist is crucial for its health. It does well in full sun in northern climates but appreciates some afternoon shade in the hot, lower Midwest and Southern regions. Plus, a layer of mulch helps to keep the soil cool and retain moisture, giving your cardinal flowers the best conditions to flourish.
