Oddly (we think, at least!) for a plant named 'rotundifolia', this attractive Hoya actually has rectangular leaves!  (Hey, folks, we don't name 'em, we just grow 'em!)  Found in Myanmar and neighboring Thailand, this species is yet another example of the incredible variety of the so-called Wax Plants!  Its blossoms are very attractive, with their cheerful, daisy-like shape and citrus aroma.  Uncommon in cultivation, but easy to grow with standard Hoya care!
