    About this genus:

    Lobelia (lo-be-le-a) is a genus named after the Belgian botanist Matthias de Lobel (1538–1616). It is in the bell-flower family (Campanulaceae) comprising almost 400 species that are distributed worldwide. 

    Lobelia prefers damp soils and in the wild is often seen growing in boggy places like swamps in sun or part shade. The flowering stalks of Lobelia 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 autumn. It is a tough, low maintenance plant which makes it perfect for wet gardens.

    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 of Lobelia which was to induce vomiting.
