Brazilian jasmine, widely known by gardeners as Mandevilla or Dipladenia, is an evergreen climbing vine native to the warm forests of South America. It is prized above all for its showy trumpet-shaped flowers in vivid shades of pink, red, and white, which bloom continuously against glossy, dark green, leathery leaves.
Often grown in patio containers, hanging baskets, or trained along trellises and railings, this vigorous plant brings an instant tropical feel to warm-weather spaces. While it thrives as a perennial outdoors in frost-free climates, it is frequently kept as a warm-season patio centerpiece or brought indoors as a houseplant before winter arrives.
Cultivating this plant successfully is straightforward as long as it receives abundant sunlight and well-aerated soil. Its tuberous roots store moisture efficiently, meaning it handles brief dry spells far better than soggy potting soil, which quickly leads to root problems. Given warmth and good light, it delivers nonstop blooms throughout the entire season.
Did you know?Despite its delicate appearance, this plant forms thick storage roots that store water and nutrients, helping it withstand short drought periods in nature.
Care
- Watering
- Water moderately once the top 3 to 5 centimeters of soil feel completely dry to the touch. In peak summer heat, it typically needs water two to three times a week, reducing to once every two weeks in winter.
- Light
- Place it where it receives plenty of bright light and at least several hours of direct morning sun each day. In scorching summer climates, provide light afternoon shade to prevent leaf scorch.
- Temperature
- The optimal temperature range is between 18 °C and 26 °C. It cannot tolerate freezing temperatures and suffers serious damage whenever drops fall below 10 °C.
- Soil
- Use a well-draining potting mix containing peat moss, coconut coir, and perlite to prevent waterlogged soil.
- Fertilizer
- Feed with a balanced bloom-boosting liquid fertilizer every two weeks during the active spring and summer growing period.
- Pruning
- Prune back straggly stems in late winter or early spring to encourage bushy growth and promote abundant new flowers.
- Propagation
- Propagate by taking semi-hardwood stem cuttings in late spring or early summer. Dip the cut ends in rooting hormone and place them in moist, warm potting medium until roots develop.

Frequently asked questions
Why are my Brazilian jasmine's leaves turning yellow?
Yellow foliage is most frequently caused by overwatering or compacted soil that retains too much moisture around the roots. Cold drafts and insufficient lighting can also prompt the plant to drop yellow leaves.
How can I encourage more flowers on my Mandevilla?
Ensure the plant receives ample sunlight, ideally 5 to 6 hours of filtered or morning sun per day. Regular feeding with a potassium-rich fertilizer throughout the spring and summer will also maximize flowering.
Can Brazilian jasmine survive the winter outside?
It will not survive freezing temperatures outdoors and must be brought inside before temperatures drop below 10 °C. Place it in a sunny room, curtail watering significantly, and withhold fertilizer until spring.
Does Brazilian jasmine need a trellis?
Yes, providing a trellis, netting, or slender stakes is ideal because its twining stems need physical support to climb upward. You can gently tie the initial vines to guide them along your desired structure.
