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.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die. Hungry animals, drought, poor soil conditions, over watering, diseases & pests are all good examples of what can cause plants to die. The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.
The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability). We may ask for photos for documentation purposes, but we try to make the process as easy as possible.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
