I'm curious, what does the word "poring" mean in your subject line? Your
Wax Plant (Hoya ranauensis) has pretty flowers and I really like those leaves! We have zero photos of that one in the database so I hope you will consider adding one or two pictures.
I've had a few Hoyas over the years without any detectable scent; one in bloom right now is Hoya 'Ruthie' which has very pretty flowers but absolutely no fragrance!
