Complete Plant Information
Overview
Mandevilla ‘Red Velvet’ is a highly valued woody-stemmed, twining tropical vine celebrated for its vigorous growth and long blooming season, making it an excellent choice for vertical interest. This patented variety, Mandevilla ‘Red Velvet’, produces large, trumpet-shaped flowers whose vibrant hue shifts dramatically based on ambient temperatures—appearing pink in cooler weather and darkening to deep red when temperatures exceed 85°F. Gardeners appreciate this genus of Mandevilla for its lush, glossy dark green foliage which provides a stunning backdrop for the showy summer and fall blooms.
As a rapid grower, this plant can quickly climb structures, reaching significant heights in warm climates or providing continuous color when grown temporarily as an annual or container specimen elsewhere. Its low maintenance level suggests it is a rewarding choice for gardeners seeking high visual impact without intensive care, provided its tropical needs for warmth and moisture are met.

How to Grow
For areas within USDA Zones 10-11, Mandevilla ‘Red Velvet’ thrives when planted or left in the ground to twine up structures like trellises, pergolas, or fences. In these warm regions, ensure the soil is moist but always well-drained. In regions outside of these zones, treat this tropical beauty as a specimen container plant or an annual.
Container culture requires a moist, well-drained potting mix; provide small trellises inserted directly into the pot to support its vertical reach. While Mandevilla prefers full sun for best flowering, plants appreciate some light afternoon shade during intense hot summers to prevent stress. Water needs are medium; aim for consistently moist soil, avoiding extremes of drying out or saturation.
Pinching back young stems encourages a bushier, more manageable growth habit rather than excessive vine length. Crucially, this plant must be protected from frost. Before the first fall frost, containerized plants should be brought indoors to a warm, sunny room for overwintering. Alternatively, the roots can be allowed to die back from frost, and the tuberous roots can be dug up and stored in a cool, dark location within dry soil. Prune vigorously in spring before returning the Mandevilla outdoors after all danger of frost has passed.
Landscape Uses
The spectacular flowering capability of Mandevilla ‘Red Velvet’ makes it an outstanding choice for adding height and tropical flair to sunny locations. Where hardy (Zones 10-11), use this vigorous vine to soften fences, cover arbors, or provide dramatic screening along pergolas. In more temperate climates, it excels as a striking focal point in large containers placed on decks or patios, utilizing a built-in support system.
When grown in containers, gardeners can pair the Mandevilla with mounding or trailing seasonal annuals that share similar sun and water requirements, such as petunias, calibrachoa, or sweet potato vine. This creates a cascading “thriller, filler, spiller” effect that maximizes visual interest throughout the warm growing season. Using upright supports ensures the woody stems of the Mandevilla can fully express their natural twining habit, maximizing the display of its large, colorful flowers.

Noteworthy Characteristics
The genus Mandevilla comprises about 120 species of primarily tuberous-rooted climbers originating in Central and South America. ‘Red Velvet’ is a patented hybrid noted for its vigorous growth, glossy dark green leaves, and large salverform flowers that bloom profusely through summer into fall. The flower color shifts based on temperature, moving from pink below 85°F to a deeper dark red above that threshold, always featuring red throats.

Potential Problems
Mandevilla ‘Red Velvet’ generally remains free from serious pest or disease issues, which contributes to its low maintenance profile. However, overwintering plants indoors can sometimes attract common houseplant pests. Be vigilant for potential infestations of whiteflies, spider mites, and mealybugs, especially when the plant is brought inside for winter storage. Regular inspection and treatment with insecticidal soap or horticultural oil can manage these minor threats effectively.
Frequently Asked Questions
What hardiness zones is Mandevilla suitable for?
This specific Mandevilla cultivar, Mandevilla ‘Red Velvet’, is winter hardy only in USDA Zones 10 to 11. Gardeners outside this range must treat it as a container plant or annual.
How large does Mandevilla grow?
At maturity, this vigorous vine typically reaches a height between 3 and 10 feet and spreads moderately between 3 and 4 feet wide.
When does Mandevilla bloom?
This Mandevilla variety is known as a seasonal bloomer, producing its eye-catching pink to red flowers consistently throughout the warmer months into the fall.
What sun exposure does Mandevilla need?
For optimal performance, plant Mandevilla ‘Red Velvet’ where it will receive full sun to part shade. In very hot climates, supplemental afternoon shade is often beneficial.
Conclusion
The rich foliage and uniquely responsive flower coloring of Mandevilla ‘Red Velvet’ establish it as a premier choice for tropical color and vertical drama in the garden or on the patio. Its low maintenance requirements further enhance its appeal as a reliable summer performer. Before planting, confirm your local USDA zone compatibility or prepare appropriate overwintering strategies for your Mandevilla container specimens.
Container Growing
Growing Mandevilla in pots is one of the most popular ways to enjoy this tropical vine, especially for gardeners outside of Zones 10-11. Select a container large enough to accommodate root growth, remembering that this vine can easily reach 7-10 feet in a single season if unrestricted. Use high-quality potting soil that ensures excellent drainage—this is crucial for preventing root rot, as Mandevilla needs consistently moist but never soggy conditions.
Container culture makes the necessary seasonal relocation simple; simply move the pot indoors before the first frost threatens the plant. When overwintering inside, ensure the location is bright and warm. Pruning in spring should be moderate to cut back the leggy stems developed during their indoor rest, preparing the Mandevilla ‘Red Velvet’ for a strong burst of new growth and flowering once placed back outdoors.
Design Ideas
The cascading and climbing nature of this Mandevilla variety lends itself perfectly to focal-point urns or large window boxes situated near seating areas. For a bold statement, plant Mandevilla ‘Red Velvet’ at the base of a strong, dark obelisk or obelisk support structure to emphasize its upright growth habit. Contrast its glossy dark green leaves with plants featuring silver or variegated foliage for maximum textural contrast during the bloom season.
When using this vine in mixed containers, ensure accompanying plants complement its medium water needs. Consider pairing it with drought-tolerant or traditional annuals, but be aware that the Mandevilla’s consistent moisture requirement might necessitate slightly more frequent watering for the entire container arrangement.
