What species is it?
Denise in Omaha
Your Hoya could be either Hoya verticillata, parasitica or acuta and many people claim that these species are all synonymous. Hoya verticillata would be the proper accepted name and this species can have different coloured flowers and leaves with markings, veins, no visible veins, a visible central vein or midrib as in your plant and varying leaf thicknesses.
thanks so much, Mike~~~
