This may seem excessive. It kind of is, too. When you don’t have curtains, an excessive amount of plants works too. I mean, what else am I going to place in a window other than plants?
Hoyas love a good amount of sunlight, even strong light from a south facing window, like this one. A new plant, or one that was previously used to less light, may need some time to get used to it, but I’ve found that the plants in this window grow much faster and bloom more often than the plants I’ve placed in partial shade.
I took a couple of pictures of my Hoya compacta variegata – one with the vines tucked away, like they usually are, and one where I let the vines grow freely. I measured both of them to be 90 cm long. Almost 30 cm longer than they were 3 months ago. I lost my normal green compacta to root mealy bugs a couple of months ago. If I lose this variegated plant, I would probably cry.
