As usual, your plants are beautiful. What are you feeding your stingray? Mine hasn't grown that much.

Do your tropical plants overwinter in a greenhouse? If so, what is your annual heating cost?

I only overwinter elephant ears, cannas, bananas, and some of the tropical houseplants, the rest are throwaway annuals.

I keep the gh cool , about 50-55. I use a commercial 220volt heater. The owner of the house/gh does not even notice a blip in the electricity bill over the winter.

"elephant ears"

It may interest you to know that you can bloom some aroids with a single high dose of gibberellic acid. In my experience, GA does not cause morphological changes in elephant ears.
