Hi Lisa,
With so many types of Hoya plants in your collection, it sure sounds like you are a true "Hoyaddict'" and will fit right in here with the rest of us! I'm getting up in age and I don't have near as many Hoyas (or or other plants) that I did 30+ years ago but I still enjoy the few that hang out on my pool deck.
Your second photo looks like an amazing spa and what a beautiful greenhouse! I really love that building style!
Again, welcome to the Hoya forum; look forward to seeing more of your photos and also your greenhouse once it's complete and filled to the brim!
