So, found a couple of my crosses blooming at the show today. Must have sold them as seedlings...
White Knight x Topaz Magic - looks like the one I have at home. Not bad!
hainanense x Donna's Bird. This was better in person than my photo, good color. Pulled it for judging.
Donna's Bird seems to make decent hybrids. I know the photo of that flower doesn't capture it the best, but I bet that flower is really stunning in person.
