I got this hoya as a cutting from a friend in the summer of 2005. H. cv Sunrise is a cross between Hoya lacunosa and Hoya obscura. This is its first flowers, which bloomed in early October this year. The flowers are about 1/4" in diameter and are quite similar to Hoya lacunosa, which has white to yellow flowers. You'll notice pink on only parts of these flowers. This is because that part of the flowers were closest to the window. I have the plant in a very bright window which faces north-west, but gets only a bit of late day sun. If this plant got more sun, I'm sure that the flowers would have more pink in them.
