I have one that had to be moved several years ago, into a location where it could receive several hours of direct sunlight. The old location was in my side yard and it bloomed well, until a nearby tree became so large that it provided shade for most of the day, whereupon it stopped blooming and the entire shrub began to tilt toward the brightest light. If I had not moved it, I think it would have eventually become horizontal upon the ground. LOL!

A few years after it was moved and began blooming again, a daffy neighbor cut it to the ground. He insisted that he thought it was a Japanese privet and he was doing me a favor by cutting it down? It has since regrown and again blooms.

See if you can find a location near the woods edge, where it can receive about 6 hours of direct sunlight. You might try it in a dappled shade location, but I suspect flowers may be sparse.

Mine came from a local nursery, about 40 years ago, but I haven't seen them offered locally in the past 2-3 decades.
You will probably have to Google for an online source. Be sure to check any vendor's reputation at GardenWatchDog before ordering. You will need to Google for that URL also, as posting it here is not permitted.
