Marsdenia sinensis, commonly known as Dregea, is a perennial vine, often grown for its ornamental features, native to forest margins, scrub areas, and along streams in Central and Southeastern China, the Himalayas, and Nepal. It can reach a height and spread of 10-12 feet (3-3.7 meters), with twining stems that allow it to climb over structures and other plants. The leaves are heart-shaped, adding to its decorative appearance. Dregea produces clusters of fragrant, star-shaped flowers that are cream-colored with purple centers, blooming profusely in the spring and continuing sporadically through summer and fall. The flowers are particularly showy and can add a tropical feel to gardens.

Dregea is valued for its ease of maintenance and the sweet scent of its flowers, which can enhance sensory gardens. It is suitable for trellises, arbors, fences, and as a ground cover in large areas. This vine prefers well-drained soil, tolerates a range of soil types, and can thrive in full sun to part shade. While it has low to medium water requirements, it benefits from regular watering during dry periods. Dregea is not commonly associated with serious disease or pest problems, but it should be monitored for common vine issues such as leaf spots or mildew. It is not known to be invasive but should be managed to prevent overgrowth in small garden spaces.CC BY-SA 4.0
