My Chinese inlaws are visiting and my father in law’s eyes widened in surprise when he saw the vine with the flowers I pulled this morning. Waah—never saw so big in china. Its about double the size here. I guess some of these “invasive” plants when they migrate to other parts of the world become gigantor versions of their counterparts from their original home. He says that in China the flowers are very nice in a light consomme with a little lean meat . They scatter the flowers on top to impart their floral flavor at the end.
