Train them up a trellis, allow them to cascade from a hanging basket, or combine them with other plants. Enjoy the long summer blooms and the butterflies, hummingbirds and other pollinators that stop by to visit.

Once divided into two different groups, dipladenias and mandevillas, botanists now consider them all mandevillas. You will find both names still in use, with “dipladenias” referring to those with a shrub-like habit, and “mandevillas” referring to a trailing vine. Whatever you call it, you’re sure to find one or more that complement your garden and container designs.

Mandevillas are grown as annuals in all zones except Zones 10a to 11b where some varieties are hardy. It blooms best in full sun but will tolerate some shade. These native South American plants thrive in hot, humid summer weather. Wait until spring temperatures remain in the 60s before planting them outside.

Select a mix or site that contains organically rich, well-drained soil. Use a slow-release fertilizer early in the season and reapply if necessary mid-season. Read and follow label directions when using rapid-release liquid fertilizers.

Mandevillas usually flower when purchased from a garden center. They will continue to bloom on new growth throughout the summer and fall off until frost kills the plant.

A well-behaved mandevilla won’t choke out nearby plants. Simply give it a trellis or obelisk for the vines to wrap around and climb up. Its slightly woody stems provide greater stability than other vines that regularly need support. Simply thread any new tendrils through the trellis and point them in the desired direction as needed.

Use vines in their own container or as a vertical accent on a trellis in mixed containers or flower beds. Place the pots at the entrance to your home or garden for a colorful welcome or use them to decorate a blank wall or fence.

More compact shrub types can be planted with other annual flowers in the garden, grown in hanging baskets, or used as filler in mixed container gardens. Simply prune or tuck any stray branches behind neighboring plants.
