Traditional Uses for the Cardinal Flower

The cardinal flower is a lovely wildflower and garden plant. It was used in days gone by as a medicinal plant by the native people of North America. Indigenous people made a tea of the root of the plant as a treatment for syphilis and intestinal problems. Drinks made from the plant’s leaves were used to treat colds and bronchial distress, and to prevent cold and flu symptoms. The dried leaves of the cardinal plant were also used as a substitute for tobacco and were both smoked and chewed. The Zuni people made a cake of the plants which were then used to treat swelling and arthritis.Any member of the genus Lobelia is potentially toxic. Studies have been done using lobelia as a treatment for neurological disorders with no conclusive medical results at this time.

Growing the Cardinal Flower

Keep the cardinal flower well watered. It prefers shade in the afternoon. Deadhead the flowers to keep the plant blooming. Pinch the tops of the plant back to make a bushier plant.

Because the cardinal flower is a short-lived perennial, it is helpful to know how to propagate the plant and keep it as an active part of your flower garden. You can also plant the ripe seeds elsewhere. Divide the plant every two to three years to keep the plant blooming and growing. Do not cut the plants back in the fall, but allow them to self-seed.
