The hot new plant I'm seeing in winter gardens this year is Edgeworthia chrysantha, the paper bush. The first time I saw paper bush, it was labeled as E. papyrifera. According to Hortus, chrysantha and papyrifera are the same species. But the two plants don't look alike to me at all. The flower clusters of E. papyrifera are small, about the size of a dime. Those of E. chrysantha are much larger, about the size of a half-dollar. And I think E. papyrifera blooms earlier. Anyone care to shed some light on this?
