Hoya mindensoris
MJ, Can you post a picture of the whole plant. I am not familiar with your plants.We just can't get the variety that warmer climates seem to get.
H. carnosa compacta & H. carnosa krimson queen.They look the same but the leaves are very different.Compacta is the curly leaves & the KQ has white in the center and green around the edges of the leaves.
One stem is pink and all the leaves on that stem are completely white. It's odd but really pretty.Unfortunately the only photo's i can find right quick like of both of the entire plants are from last summer.I do need to take photo's for this summer.
You can see the pink stem and white-pinkish leaves only on the pink stem.The 2nd photo is the compacta in bloom last summer.
