I have had to bring in most of the hoyas except a couple so they are filling my house and windows. Who really needs window treatments when you have hoyas? I have left hoya serpens and hoya carnosa variegated outside and they love it, especially serpens. Hoya serpens has grown so many little leaves since it cooled down. When I first received it, some of the vines died back and the peduncle fell off but you can't tell now.
