In North America night scented phlox, no idea if they might be in RD. Easily grown from seed and do well in pots if you can get hold of seeds.
Yes. And moonflowers. The reverse of morning glories. I had good luck with them in my terrace garden when I managed the hotel. I bet night-blooming jasmine (I can't STAND the smell) works. And there are indigenous cacti that also serve.
But I would say, if you are a North American, bring in/buy in (Amazon) moonflower seeds. They are not invasive.
I also can't believe that as a former employee of the NY Botanical Garden(a fundraiser, not a botanist)that I just said that. But I did.
