Thanks for the recipe Cinta! China Lake is on my "Dream" list to get someday. It is just beautiful!!!
I also have a night bloomer that looks a lot like the white one you showed. It is very old, more than 20 years. this year it had 18 blooms on it in one night. I am guessing my new cuttings of all different colors will take 3 years to get to blooming. Oh well, it gives me one more thing to live for!
