Diamantina™ Opal Yellow Mandevilla is an easy-care vining plant that boasts beautiful flowers. The bright yellow blooms have rounded petals with dark, golden yellow throats. New flowers bloom summer into early fall and are surrounded by lush green foliage. This Mandevilla hybrida is also known as rocktrumpet, and the vines can reach up to 60 inches. Carefully hand-train the vines along a trellis to create a showy display.
This low-maintenance plant thrives in a landscape or container. Feature Mandevilla in a hanging basket so the vines can cascade down and create a curtain of greenery. This plant is very well suited to warm summer weather, and it is both heat- and drought-tolerant. Mandevilla hails from tropical and subtropical climates, and the beautiful blooms attract pollinators like hummingbirds and bees.
Diamantina™ Opal Yellow Mandevilla Care
Plant Mandevilla in a spot that receives full sun. This plant can handle six or more hours of direct sunlight. Water this plant when the soil starts to dry out. Use rich, slightly acidic to neutral soil that promotes drainage for best results and feed the plant every other week using balanced, water-soluble fertilizer. Let the vines grow or trim them back in the spring to maintain a bushy look.
In USDA zones 9 through 11, Mandevilla can overwinter outdoors. In colder regions, the plant can live indoors during the winter. Trim back the growth and place the potted plant in a sunny window. Water when the top several inches of soil dries out. Hold off on fertilizing if the plant is dormant and not actively growing.
Diamantina™ Opal Yellow Mandevilla Spacing
This large vining plant can grow 12 to 60 inches tall and spread 12 to 16 inches across. Space plants 24 inches apart to create a full planting or feature in a 10- to 12-inch container.
