Akebia - "On a summer afternoon, a swallowtail butterfly was flying around looking for flower nectar. She stopped on a pine branch to rest and there met an inchworm named Lerun. They chatted a while. Lerun told the butterfly of his life-long desire to fly and she ageed to take him on her shoulders if he would show her where she could find some flowers. They flew to a clearing in the woods and there they saw thousands of Akebia flowers in full bloom. It was a wonderful day for both of them."
