Gloxinia  is the florists' name for plants belonging to the genus Sinningia, tropical American plants. They have beautiful, many-colored, funnel-shaped flowers and velvety leaves. Seeds should be sown in February; and if the young plants are carefully potted, they flower the first year. They require the temperature of a warm greenhouse during the summer months; but as the leaves die away in autumn, the roots may be stored in a dry place, merely protected from cold. They like a sandy soil, containing abundance of leaf-mould and heat.
