Phrag Don Wimber, using a Phrag besseae flavum as one parent. It gives more peachy shades. This particular flower has very wide petals, but they cup a bit at the apical portions. Also, sometimes the flowers have a color break. When it blooms well, it is very good.
OMG! That is just beautiful. My Don Wimber (not flavum) is just starting to spike. Yes, your petals are much wider than what I am used to seeing in Don. Makes yours quite unique (as if the shade of coral doesn't!). The flower shape looks like it could be award-winning.
