With Hundreds of Hoya imperialis Flowers Behind Me, I Still Get Excited To See More

Hoya imperialis does not grow nearly as well for me any longer and I have no real idea as to why. I have difficulty getting those really dark green leaves that I used to have without thinking about it. I suspect it is the lighting that I have moved to does not suit it like the old T-5 fluorescents. Anyhow I did just get this one to flower at a little over one year of age.
