I make it a point to only acquire Hoyas with very eye-appealing leaves since that's what I'll be looking at the vast majority of the time. Here are a few of my favorites, starting with macrophylla:

H. deykeae:

H. krohniana:

H. fungii:

H. Chicken Farm:

H. verticillata albomarginata:

I could go on and on and I'll pop in and add other favs as I think of them. In the meantime, hope to see some of your favorite leaves!
