@MardieJane, Yes, both Rockledge and Riverview, Florida are zone 9b. If you upload photos, we might be able to identify which Hoyas you have.
My Hoyas are pretty much all sporadic bloomers, due to me being so lax about remembering to feed them.
When I do remember to fertilize in spring/summer, I use an orchid bloom booster plant food. That being said, I do have a
Wax Plant (Hoya pubicalyx) that blooms a couple of times a year.
My first Hoya was a very small (2 inch pot) of
Krimson Princess Hoya (Hoya carnosa 'Rubra') that was given to me by a co-worker in 1976. It grew huge over the years and eventually reverted back to solid green. I had that Krimson Princess for 38 years!
At one time I had more than 50 Hoyas but I've downsized a few times over the past eight years and gave away lots of Hoyas as well as other plants. I still grow a few Hoyas and mine stay outside year round (except for the tiny
Wax Plant (Hoya heuschkeliana) that lives in a bathroom.
I don't think it matters what type of pot Hoyas are grown in, the important thing is good aeration and adequate drainage, to prevent root rot. My Hoyas have always been grown in plastic pots.
