Mandevilla 'Red Velvet' is a patented hybrid vine from the Apocynaceae family, bred through self-pollination of Mandevilla 'PSJAM DPI' to create a show-stopping tropical climber with large pink-red flowers. Hardy only in zones 10-11, this woody-stemmed twiner grows aggressively, reaching 7-10 feet in a single season when container-grown, and can stretch even taller in ground in frost-free regions. The real draw is those large, showy blooms that arrive seasonally, combined with the plant's ability to thrive in sun to part shade and tolerate moderate water needs with minimal fussing.

Mandevilla 'Red Velvet' grows with remarkable vigor, producing 7-10 feet of growth in just one season when container-grown, making it an instant tropical accent for patios and porches. The large, showy pink-red flowers arrive reliably throughout the growing season, creating a striking focal point against the dark, wrinkled green foliage. As a woody-stemmed twiner, it naturally climbs small trellises and arbors with minimal intervention, and it tolerates both full sun and partial shade, adapting to different light conditions across the day.
Mandevilla 'Red Velvet' serves as a tropical ornamental vine for container cultivation in temperate regions and as a landscape climber in frost-free zones. In cooler climates like St. Louis, gardeners grow it in large containers supported by small trellises, creating portable tropical accents for summer patios and garden rooms. In zones 10-11, it can be planted directly in ground to reach its full height and cover arbors, walls, and fences with abundant showy blooms.

After the last frost date in spring, harden off overwintered plants by gradually exposing them to outdoor conditions over 7-10 days before setting them in their final location. Choose a spot in full sun to part shade with protection from intense afternoon sun in hot climates. Space containers or in-ground plants 36-48 inches apart to allow room for the vine's mature spread.
Pinch growing tips throughout the season to encourage bushy, branching growth rather than a single main stem. Before moving plants outdoors in spring after overwintering indoors, prune stems back to shape the plant and remove any dead or weak growth accumulated during dormancy.

“Mandevilla 'Red Velvet' represents a deliberate breeding effort by hybridizers to develop a superior ornamental vine. The variety was created through self-pollination of Mandevilla 'PSJAM DPI' and earned U.S. Plant Patent PP10,413, marking it as a protected cultivar with distinct characteristics. The genus itself contains about 120 species of mainly tuberous-rooted climbers native to Central and South America, and was named in honor of Henry John Mandeville, a British Minister stationed in Buenos Aires from 1773-1861, cementing the plant's transatlantic journey from South American tropics to cultivation worldwide.”
