Hortica, those Hoyas at the Portland Airport are so cool looking! Hoya australis is my favorite for fragrance.
Gina, your greenhouse must be amazing!
I have a hanging basket of Hoya/Eriostemma 'Ruthie' that I hung in a tree a couple of years ago; some of it reached the ground and trailed along the ground but other stems began climbing the metal "S" hook and headed up into the tree.
