Popular Hoya plant. Very easy to propagate
Hoya are special in the sense their leaves don’t seem to degrade ever. Once a leaf is formed you have it for life.
Variegation is not unstable meaning there’s no way it can revert back to a plain leaf like the Hoya Princess can.
I’ve seen this particular plant produce pink outer edges during summer. I think the colour of the variegation is care dependant.
To propagate just ensure the node (area the leaf pops out of) is buried in slightly damp potting mix. You can grow this hydroponically in your fish tank as well.
