The Mandevilla has delicate pink, 2- to 3-inch flowers are backed by glossy green foliage. Superior branching and a somewhat compact habit make this an ideal choice for a trellis or hanging basket, or a container with climbing support.
Mandevilla are known for their showy flowers. There are about 100 species of this tropical American woody vine. Most species overwinter only in the tropical South. In Oklahoma they can be treated as annuals. Mandevilla is great trellised in containers or in hanging baskets. Quantities of fragrant flowers compensate for sparse foliage and for the care mandevillas require. The flowers are produced in early summer and again in early fall, even when plants are very young.
Provide enriched, moist, slightly acidic, well-drained soil. During the warm season, water regularly but do not over water during bloom period; leaves will drop if too dry. Water sparingly in winter to avoid cold, wet soil. Apply fertilizer in spring. Prune annually to control size. Provide support such as a trellis or arbor.
