(Ipomoea purpurea) This free-blooming American heirloom has twining vines with heart-shaped foliage that quickly forms a romantic leafy canopy. Grandpa Ott’s velvety, intensely purple flowers are subtly accented with a wine-red star and make a vivid garden display. These seeds have been lovingly tended for years by Grandpa Ott’s family and the Seed Savers Exchange. The vigorous, early-blooming vines blossom throughout the season, and the trumpet-shaped flowers always attract and satisfy hungry hummingbirds.
