Primrose Jasmine (Jasminum mesnyi. 黄馨).
In spite of intermittent rain, Wangling Park was full of young women taking their pictures beside blossoming pruni, redbuds, and (to a lesser extent) magnolias. The gardens of Spring are beautiful and away from the throngs there are more subtle flowers, including this primrose (or Japanese) jasmine, hiding amid a weave of weeds and vines.
