I'm a bit late to the party. You posted some very good pics of Greendragon
My property in north central IN was overrun with invasive Honeysuckle. After years of just cutting it back, I finally took a chainsaw in early spring and cut a swath to the ground. By early summer a strange new plant made it's appearance. (I named it George.) The strong summer sun was killing it, so I moved it to a shady location where it flowered. I collected the seeds, spread them haphazardly and now enjoy several clumps.
