Ornamental Sweet Potato Tuberous Roots: Edible
But are they Palatable?
Rosie Lerner, Extension Consumer Horticulture Specialist, Purdue University
Ornamental sweet potatoes are quite popular as
trailing plants for containers and annual ground cover in the landscape.
Breeders select ornamental cultivars based on attractive foliage, not for
edible quality. So while the tuberous roots of the ornamental cultivars
are “edible”, they are likely not of the same quality flavor and texture as
those selected for eating. Also note whether those grown as ornamentals
have been treated with pesticides that would not be labeled for use on edible
sweet potatoes, though typically not a problem in the home garden.
