Jasmine Brazil, also known by its botanical name Mandevilla sanderi, is a popular ornamental plant known for its vibrant, trumpet-shaped flowers. This vine brings a tropical feel to gardens and patios, displaying consistent color in warmer months. Its blooms and vining habit make it a popular choice for enhancing outdoor spaces.
Understanding Jasmine Brazil
Mandevilla sanderi is commonly known as Brazilian jasmine or pink trumpet vine, often sold simply as Mandevilla or Dipladenia. Native to Rio de Janeiro, Brazil, this species thrives in tropical and subtropical climates. It is a woody climbing vine, typically reaching 3 to 10 feet, with some varieties up to 15 feet. Stems grow quickly, becoming woody and twining around supports.
Its glossy, dark green leaves are oval-elliptical or lance-shaped, typically 2 to 2.5 inches long. These thick, leathery leaves are arranged oppositely. The striking flowers appear in pink, red, and white, often with a yellow throat. They are trumpet-shaped with five spreading petals, 1.5 to 4 inches in diameter, appearing singly or in clusters. Flowering extends from spring through autumn, with nearly year-round blooming in frost-free regions.
Site Selection and Planting
Selecting the right location is important for a healthy Jasmine Brazil. It thrives in full sun, needing at least six hours of direct sunlight daily for optimal flowering. In intense summer heat, afternoon shade protects foliage from scorching. Protection from strong winds is also beneficial.
Prepare well-draining soil rich in organic matter for both in-ground and container planting. A sandy loam soil with a slightly acidic to neutral pH (6.6-7.8) is suitable. For containers, select a pot with ample drainage holes and use a quality potting mix, amending it with peat moss, sand, or perlite to improve drainage.
When planting:
- Dig a hole slightly larger than the root ball.
- Carefully remove the plant from its nursery container.
- Gently loosen any compacted roots.
- Place the plant so the top of the root ball is level with or slightly above the surrounding soil.
- Backfill with soil, tamp lightly to remove air pockets.
- Water thoroughly to help it settle.
Ongoing Care Requirements
Jasmine Brazil thrives with consistent care. It requires warm temperatures, ideally 70-90°F (21-32°C) during the day and no lower than 50°F (10°C) at night. High humidity (50-60%) is preferred; misting helps in drier climates. Regular watering is needed, but allow the top inch or two of soil to dry partially between waterings to prevent root rot. While the plant tolerates some dryness, consistent moisture promotes better flowering.
To encourage abundant blooms, fertilize during the growing season, applying a balanced fertilizer or one higher in phosphorus every two to three weeks from spring through fall. Reduce or cease fertilizing in fall and winter, especially if overwintering indoors. Pruning maintains the plant’s shape, encouraging bushier growth and more flowers. Prune in late winter or early spring before new growth begins, as blooms appear on new growth. Support structures like trellises, arbors, or pergolas are useful for its vining habit, allowing the plant to climb and display flowers.
Common Pests and Diseases
Jasmine Brazil plants are robust, but can encounter pests and diseases. Common pests include aphids, spider mites, mealybugs, and whiteflies. Aphids appear as small clusters on new growth, leaving sticky honeydew on leaves. Spider mites cause tiny yellow dots on leaves, leading to leaf drop, and may produce fine webbing. Mealybugs leave waxy deposits in branch crotches and excrete honeydew.
Prompt treatment is important if an infestation is detected. Insecticidal soap or neem oil can be effective for most pests. For whiteflies, a strong water spray can dislodge them. Fungal diseases can occur from overly wet conditions; good air circulation and proper watering prevent these issues. Removing affected leaves can also help manage disease spread.
