Grow big, beautiful, delicious sweet potatoes from plants sent directly to you from our friends in Gleason, TN. Plant these vining plants 15" to 20" apart and enjoy the beautiful flowers they produce before harvest time. Ready to harvest in about 90 days. Sweet potatoes will ship separate from onion plants. Plants are shipped from late April to early June depending on your location. They cannot take a freeze. We apologize we cannot ship sweet potato plants to California.
