Sweet Caroline ‘Light Green’ Sweet Potato Vine at NC Arboretum, Asheville, NC<\/p><\/div>\n

\"Ipomoea<\/a>

Illusion ‘Midnight Lace’<\/p><\/div>\n

Ornamental sweet potato vines (Ipomoea batatas<\/em>) have been around since the late 1980’s, but their popularity have soared over the past decade. These sweet potatoes aren’t for the table. The colorful vines\u00a0thrive in the intense heat of U.S.\u00a0summers from May through September (zones 5-11).<\/p>\n

These easily grown plants work well as a low-growing bedding plant, summer ground cover, weepers in hanging baskets and large containers, or vertically climb with trellis support. Older varieties, like Margarita and Blackie, were almost too\u00a0vigorous and new introductions come in more color choices and grow more compact. Ornamental sweet potato cuttings will root effortlessly in water or soil.<\/p>\n

Colorful foliage<\/strong><\/p>\n

Their colorful foliage is the big show. Ornamental sweet potatoes generally do not flower under normal garden conditions. Small, lavender, trumpet-shaped flowers may form in late summer or fall and are mostly hidden under the foliage.<\/p>\n

Ornamental sweet potatoes do best and are most colorful in locations that receive 6 hours or more of direct sunlight. They do grow in shadier locations, but vines are not as vigorous or colorful. Average garden soil, fertility and lots of water is all they need.<\/p>\n

Insects to watch for<\/strong><\/p>\n

Sweet potato vine is relatively carefree, there are a few problems to watch out for. Pest problems include the sweet potato looper, a caterpillar that chews holes in the leaves, and the sweet potato whitefly.<\/p>\n

Control the looper with occasional applications of an insecticide containing BT, spinosad, a pyrethroid (permethrin, bifenthrin, cyfluthrin and others) or carbaryl (Sevin). Wwhitefly can be managed with Summer Light Oil Spray, bifenthrin (Talstar\u2122or Malathion. Disease issues are minimal.<\/p>\n

Newer cultivars<\/strong><\/p>\n

New cultivars display various leaf shapes, growth rates and foliage colors. Some feature shorter stem nodes between the leaves, reduced root size, and more compact habit.<\/p>\n

Spotlight series<\/strong> (lime, red, black foliage) new for 2017 from Ball FloraPlant<\/p>\n

SolarPower series<\/strong> (black, lime, red foliage) new 2016 from Ball FloraPlant<\/p>\n
