Gardeners' Notes:


On Jul 23, 2012, palmbob from Acton, CA (Zone 8b) wrote:

this is one of the hardier Hoyas that I have grown and though I do have it protected from full sun and under an eave, it survives our intense heat (over 100f), low humidity (down below 20% sometimes) and cold (down to 25F sometimes, though probably a bit warmer under the eaves). Slow growing but a reliable flowerer every summer.

I live in zone 8b and this plant grows VERY well and flowers profusely. I do take it inside, to my greenhouse over the Winter and bring it back outside in early Spring.
I love this plant, so hardy and beautiful!

Please note:
Although it grows in my area, NO HOYA is cold hardy and must be protected!
