White dipladenia (Mandevilla boliviensis)
Discover the beautiful Mandevilla boliviensis, or White dipladenia, a tropical vine prized for its showy white flowers with yellow throats.
Complete Plant Information
Overview
The White dipladenia, scientifically known as Mandevilla boliviensis, offers elegant, tropical flair with its distinctive, large white flowers set against glossy green foliage. This woody-stemmed vine is highly prized for its continuous bloom display throughout the warm season, providing excellent vertical interest in the landscape. While native to Central and South America, this plant thrives as a reliable annual or a protected container specimen in cooler climates. Gardeners appreciate the bright visual impact that Mandevilla boliviensis brings to patios, baskets, and vertical garden structures.
This twining vine requires consistent moisture and ample sunshine to achieve its best growth, reaching heights up to 10 feet when fully supported. For those cultivating Mandevilla boliviensis outside the tropics, careful attention must be given to its overwintering needs to ensure its return the following year. Whether allowed to sprawl or trained upwards, the stunning white blossoms of the White dipladenia make it a must-have choice for a summer showpiece.

How to Grow
Plant the White dipladenia in a location that receives full sun to part shade exposure. In excessively hot regions, providing some afternoon shade can prevent leaf scorch and maintain vibrant color, especially when growing Mandevilla boliviensis in containers. The potting medium should be a moist, well-drained mix; standard, high-quality container soil works well for this tropical species.
Water needs for this vine are moderate; ensure the soil remains consistently moist but never waterlogged. If grown in hanging baskets or standard containers, check the soil moisture daily during peak summer heat. When grown as a vine, insert small trellises—typically no taller than 3 feet—into the pot to provide immediate support for the twining stems. Pinching back stems sporadically will encourage a bushier, more densely branched habit rather than a purely vertical climb.
Because Mandevilla boliviensis is only winter hardy in USDA Zones 10-11, gardeners in colder regions must prepare for dormancy. Bring plants indoors before the first frost, overwintering them in a warm, sunny room to mimic their tropical origins. Before placing them back outside in spring after all danger of frost has passed, prune the stems back moderately to encourage fresh, vigorous growth.
Landscape Uses
The versatility of Mandevilla boliviensis shines in both warm and temperate garden settings. In Zones 8 through 10, this outstanding vine is perfect for softening structures, cladding fences, adorning arbors, or ascending pergolas, offering a screen of glossy green foliage punctuated by bright white flowers. For regions colder than Zone 10, it excels as a dramatic annual display or a stunning focal point in containers.
Containers are the ideal setting for the White dipladenia in non-tropical zones, allowing gardeners to move the plant easily indoors for winter protection. Pair it with trailing annuals like petunias or sweet potato vine in mixed planters for textural contrast, or use it solo in a large pot to showcase its climbing habit against a wall or railing. Its brilliant white blooms contrast beautifully with deep purple or dark-leaved companions.

Noteworthy Characteristics
Mandevilla boliviensis is a woody-stemmed, twining tropical vine or sprawling shrub native to Bolivia and Ecuador. It features elliptic, oblong, shiny dark green leaves up to 4 inches long. The prominent feature is the large, white funnel-shaped flowers, spanning 2 to 3 inches across, which flare into five pointed lobes and showcase distinctive yellow throats. When grown in containers, this plant typically adds 3 to 5 feet of growth during a single season.
Tolerances
Potential Problems
Mandevilla boliviensis generally resists serious insect or disease issues when grown outdoors in ideal conditions. However, pest management becomes more critical during the winter dormancy period indoors. Watch closely for common houseplant pests such as whiteflies, spider mites, and mealybugs, which often congregate on overwintering plants protected from natural predatory controls. Regular inspection and treating any infestations immediately with insecticidal soap can prevent these minor issues from becoming major setbacks before the spring growing season.
Frequently Asked Questions
What hardiness zones is White dipladenia suitable for?
The White dipladenia (Mandevilla boliviensis) is winter hardy only in USDA Zones 10 and 11. In colder areas, treat it as a container plant or annual.
How large does White dipladenia grow?
When supported as a vigorous vine, Mandevilla boliviensis can reach up to 12 feet, though container specimens often top out between 3 and 10 feet in height, spreading 3 to 6 feet wide.
What sun exposure does Mandevilla boliviensis need?
This plant prefers full sun but appreciates some protection from the harshest afternoon sun, particularly in very hot climates, thriving best under full sun to part shade conditions.
When does Mandevilla boliviensis bloom?
This species is a seasonal bloomer, producing its attractive white flowers with yellow throats throughout the summer months.
Conclusion
For stunning vertical impact and vibrant summer color, the Mandevilla boliviensis offers an excellent solution, especially appreciated for its bright white flowers. Whether trained up a trellis in the southern landscape or managed as a treasured patio container, the White dipladenia brings undeniable tropical elegance. Before planting, carefully assess your local USDA zone and ensure you have a plan for protecting this beauty if temperatures drop below 40°F.
Companion Planting
Selecting appropriate companion plants ensures that Mandevilla boliviensis has an aesthetically pleasing and culturally compatible setting. Since this vine needs medium water and prefers well-drained soil, pair it with other sun-loving annuals that share similar moisture requirements, such as Lantana, Calibrachoa, or Verbena. These partners offer different textures and blooming habits, creating rich layers around the base of the vine or spilling over the edges of containers where the Mandevilla boliviensis is twining above.
When using this plant in a container arrangement, focus on spillers and fillers that don’t require substantially more or less water, which can create inconsistent soil saturation. Darker foliage plants, such as black Mondo grass or certain varieties of Ipomoea, make the bright white flowers of the White dipladenia truly pop, enhancing the overall drama of the display throughout the growing season.
Container Growing Tips
Growing Mandevilla boliviensis in containers simplifies its care, especially managing its overwintering needs outside of Zones 10–11. Always choose a container large enough to accommodate at least one season’s growth and provide stability for vertical support. A pot at least 14–16 inches in diameter is a good starting point for a season plan.
Use a light, fluffy potting mix amended with extra perlite if necessary to guarantee enhanced drainage, which is critical for the health of tropical roots. Regularly feeding a dilute, balanced liquid fertilizer every two to four weeks during the active growing months supports the heavy bloom production characteristic of this species. Monitor the plant inside during winter, ensuring it receives bright light and avoiding overwatering, as low light and wet soil are the primary causes of failure for overwintered Mandevillas.
