Plant Species of the genus Ruellia

Information about this genus
Name: Ruellia
Cultivation: CULTIVATION: Although some species from temperate America are quite frost hardy, most need a warm climate and a fertile, moist, well-drained soil in partial shade. In cooler areas they are grown indoors or in a greenhouse. Water potted specimens adequately during the growing season and keep just moist during winter. Trim excess growth regularly and especially after flowering to maintain density of foliage. Propagation is from seed or softwood cuttings in spring.
Description: Mostly from tropical and subtropical regions, with a few species in temperate North America, this is a genus containing some 150 species of evergreen perennials and soft-stemmed shrubs. They are grown either indoors or out for their showy funnelform flowers, usually red, pink or mauve, that may occur singly, or in dense terminal panicles or axillary clusters. The attractive, smooth-edged, oblong to lance-shaped leaves have prominent veins.
