Margarita Sweet Potato, with its striking chartreuse foliage, sets the summer landscape aglow. It makes a dramatic statement when planted with Blackie. Another selection is Tricolor, which has shades of pink, magenta and green all in the same leaf. In addition to landscape planting, ornamental sweet potatoes are great plants for trailing over the sides of raised planters or large hanging baskets. Make certain baskets are at least 18 inches in diameter to provide enough rooting area and moisture to support the vigorous top growth.
Many people ask if the roots of ornamental sweet potatoes are edible.
The answer is yes, but they are not very palatable. Plant edible types if sweet potato pie is in your future. Full sun to partial shade. Cuttings taken from established plants are easy to root. Roots may be dug and overwintered for spring planting.
