Plant Details

These beauties outfit a yard with sizzling summer color.


Flowers: Trumpet-shape blooms unfurl 2–3 inches wide. Sun Parasol Giants open 3–5 inches across.


Use: For vertical color, tuck this natural climber into a 3- to 4-foot trellis in a 12-inch planter. Pair mandevilla with a trailing vine in a large 15-inch hanging basket. Flowers attract butterflies and hummingbirds.


Needs: Plants flower best in full sun. In hottest zones, midday shade is a bonus. Vines grow most vigorously in the heat of summer; growth slows as temperatures drop.


Planting: Use one plant per 10–12-inch flowerpot. In planting beds, space plants 18–24 inches apart.


Soil: Mandevilla prefers well-drained soil. In containers, choose a soilless mix containing slow-release fertilizer and water-retention polymers.


Watering: Keep soil consistently moist for steady flowering. If soil dries out for a short time, plant growth will revive, but flowerbuds may drop.


Fertilizing: You can fuel mandevilla’s vigorous growth and flowering with frequent feedings, every 14–21 days. Use a bloom booster fertilizer to increase flower numbers.


Overwintering: In cold climates at least four weeks before frost, give plants a high-phosphorous fertilizer. Three weeks later, trim plants to 12 inches above soil. Bring plants indoors before temperatures tumble into the mid-40s. Place plants by a bright window through winter, watering enough to keep leaves from shriveling. Move plants outside in spring, trimming lanky winter growth.
