Stunning photos. They absolutely are beautiful flowers and the smell...wow. I live in Thailand. They were traditionally called longtam (bad thai) translated as melancholy and were traditionally found in temples, cemetaries or courts. They now popularised and called wa la dii. I was so blown away.by them i painted a large peice. Inspired by georgia o Keefe
