Gardeners' Notes:

Neutral Vestia On Feb 19, 2012, Vestia from San Francisco, CA wrote:

It is a coarse-textured vine with dull leaves, but it flowers easily. The nectar from the flowers runs profusely and stains.

This info is for growing hoyas in the Pacific Northwest. Hoya fraterna/aff. Fraterna flourishes in a southwest-facing window.

Neutral AlohaHoya On Jan 22, 2006, AlohaHoya from Keaau, HI (Zone 11) wrote:

Some feel Schlecters ID of H. fraterna is questionable, as his notes were included in his papers on H. coriacea. H. coriacea and what is sold as H. fraterna are identical without flowers, and the flowers are very different. As a positive ID is not possible, it is assumed that the Hoya in circulation from Ted Green as H. fraterna and from Aloha Hoya as H. aff fraterna are the same. They may be subspecies of eachother or separate species.
