Background: Derived as a sport on Hoya carnosa ‘Exotica’, this Hoya started off in the late 60’s and has been a part of Hoya horticulture ever since. It is widely available, easy to grow, and often chosen for it’s unusual and attractive leaves with 6-10 depressions or dimples (for which it was named ‘Krinkle 8’) appearing in the leaf blades. Please see the patent for the full description including color ranges specific to each part.
Secondary Publications: This cultivar has been published many times over the decades, appearing in sales lists and hobby journals all over and especially concentrated in the United States and Sweden. Of particular note, it was covered by C.M.Burton in The Hoyan 20(1) 1998, on the cover in full bloom, and on page 3 : “Hoya carnosa cv.Krinkle-8 is one of the best hoyas.”.. you can read a full column of this in her article. This is a nice publication because it covers how it grows.
