I wonder to know why hoyas in Brazil never gives seeds!
I have a group on facebook The Hoya Club of Thailand and all the people post pictures of hoyas seeds. Here me and my friends never saw a single seed. My family has carnosa for more than 20 years and I never saw seeds.
Does anyone knows why? The polination is done by bees, ants and other insects common here!
