The Many Attributes Of The Red Cardinal Flower
Red cardinal flowers, also known as Lobelia cardinalis, thrive in warm weather and moist, fertile soils. Cardinal flowers have numerous positive attributes and are an excellent planting for summer gardens and landscapes. Here are few of the plant's noteworthy features:


Colorful Blooms


Cardinal flowers' red blooms are vibrant. They pair well with other primary colors like blue and green. Choose moisture-loving companion plants like ferns or yellow coreopsis. Since cardinal flowers are lush and dense, they form colorful beds that are certain to delight.


Sweet Nectar


Hummingbirds are drawn to cardinal flowers' red blooms and stay for the flowers' sweet nectar. Swallow-tailed butterflies also make an appearance. Fortunately, deer do not appreciate cardinal flowers and stay away. For those interested in attracting bees and other pollinators, this brilliant flower will welcome many visitors to your garden.


Easy Planting and Maintenance


Cardinal flowers spread by seed and by offsets. After a few seasons, you will have a full bed of cardinal flowers. To speed the process, shake a few flower stalks over moist soils to spread seed. Keep leaf litter and other yard debris clear of the growing area to prevent damage to offsets. When healthy, offsets clump together to create stands of towering cardinal flowers.


The plants reach between two and four feet in height. They bloom from mid-summer until early autumn. They prefer shade but can withstand full sun if they receive plenty of water. Gardeners and landscapers choose this plant when creating textured height and accents along foundations. In these locations, cardinal flowers can enjoy both shade and water run-off.


Multiple Garden Uses


Cardinal flower growers have found success by planting the flowers in water gardens, shade gardens, wildlife gardens and near irrigation spouts. Cardinal flowers can be placed in containers, but they will need frequent watering. However, they make an eye-catching specimen on balconies and patios.
