Mandevilla splendens, commonly known as Shining Mandevilla, is an evergreen perennial vine native to the Serra do Mar mountain range of Southeast Brazil, where it thrives in the warm, humid conditions of tropical and subtropical forests. It can reach lengths of up to 20 cm (7.9 in), with twining stems that climb on supports. The flowers are a striking rose-pink with yellow throats, blooming profusely from late spring to early summer. Each trumpet-shaped flower can be up to 10 cm (3.9 in) in length, creating a showy display. Shining Mandevilla is particularly noted for its glossy, dark green leaves which add to its ornamental value.

This vine is celebrated for its beautiful flowers and is often used in cultivation for trellises, arbors, and hanging baskets. It has earned the Royal Horticultural Society’s Award of Garden Merit, indicating its excellence for garden use. While it prefers temperatures above 5–10 °C (41–50 °F), in temperate zones it must be protected or brought indoors during winter. It requires a sheltered location with full sun exposure and benefits from medium water and well-drained soil. Although it is relatively easy to maintain, it can be susceptible to pests such as spider mites and aphids. Gardeners should also be aware that all parts of the plant are toxic if ingested.CC BY-SA 4.0
