I don't grow it but a friend has it, as a conservatory plant and it is stunning. He considers it to be tender. but we are in Yorkshire.

I know that one - a weed around here. My neighbor across the street planted it and now it is everywhere. Since it thrives so well in the Azores, I would call it a tender shrub. It does scent the night air, but is unremarkable during the day. Best tip: don't let it go to seed. It grows in semi-shade to full shade, bounces back from really hard pruning (hard to kill unless I pull it out).
