I love the white R.O.S.'s!! Here's a picture of an old heirloom white R.O.S. It's growing in a patient's yard next to a light purple & pink R.O.S. All three trees are about 20 + ft. tall, and all 3 bloom the same three colors year after year. The white R.O.S. is a very bright pure all-white. This was the first true white R.O.S. I had ever seen. These plants were planted by my 82 yr. old patient's mother.
