| The Rio series mandevillas sport glossy foliage and broad, showy, trumpet-shaped flowers that come in pink, hot pink, and deep red. These mandevillas grow upright with little twining. These compact plants grow best in patio containers, and can be grown alone or mixed with other annuals wherever a splash of color is needed. They tolerate summer heat, but would benefit from some afternoon shade.
Winter hardy to USDA Zones 10-11. Zone 7 and north this plant is usually grown in large containers that are overwintered indoors. When growing as a vine, small trellises (to 3’ tall) are usually inserted in the containers for the plants to grow upon. Bring plants indoors in fall before frost and overwinter them in a warm, sunny room. Prune plant stems back before placing them outside in spring after last frost date. Best with a moist, well-drained potting soil in full sun to part shade. Appreciates some part afternoon shade in hot summers. Pinch to promote shrubby growth.
These mandevilla hybrids produce deep pink flowers. They are woody-stemmed, twining tropical vines that grow to 20’ in Zones 10-11 where they can remain in the ground year-round. When grown in containers, they will grow much shorter, typically producing up to 3-5’ of growth in a season. Features large, funnel-shaped, deep pink flowers that flare into five rounded lobes (to 3-4” across). Flowers have yellow throats. Blooms in summer. Oblong, wrinkled dark green leaves to 3-8” long. Stems exude a milky sap when cut. Synonymous with Dipladenia x amabilis.
