More Information About Lobelia
Lobelia is a genus in the campanula family comprising almost 400 species that are distributed worldwide. Some species are great native plants for both woodland gardens and full sun borders. According to the Victorian practice of floriography or 'language of flowers', sending a floral arrangement of lobelia was a sign of malevolence or ill will. Perhaps that was tied to one of the traditional herbal uses which was to induce vomiting.
Tips for Growing Lobelia (Cardinal Flower)
Lobelia prefers damp soils and in the wild is often seen growing in boggy places like swamps. The flowering stalks arise from flat green winter rosettes and provide rich jewel tones of red, pink, blue and more. Lobelia flowers generally begin forming in midsummer on tall stalks and may last into the early fall. Be sure not to cover your rosettes with mulch in winter.
