The Color Variability of Hoya macgillivrayi Flowers

I’ve talked about this before but it bears repeating that the coloration of Hoya blooms is highly variable depending upon the conditions under which it is grown. I have not had these really dark flowers without lots of center white on Hoya macgillivrayi since I first flowered it over 10 years ago. The piebald coloration of the flowers is nice, but not nearly as beautiful as the completely dark ones.
