Seeds from this and very hard to find, wild Cotton Morning glory or Tievine Ipomoea cordatotriloba. These 2 inch lavender with darker center blossoms covered this vine sometimes over 50 in blossom at one time from May thru October in my South Georgia garden. The somewhat heart shaped leaved with the three distinctive lobes account for its name. Six hours of sunshine and never letting this dry out seemed to be the key to the success of this plant.
