Hoya Imperialis var Rauschii

This plant is one of the fastest growing hoyas I have. I got this one in 2010 from Joni at SRQHoyas. I used to have a pink Imperialis but it lost all it's leaves and died for some reason. I also have mosaic but it only has 2 leaves and it is showing some new growth. I let these plants sit out when it rains and they seem to love it.
