I finally took pictures of that tree that produces three different kinds of camellias. I couldn't get all three into one shot, so the first photo shows two of them, and the second one shows the pure white one. They're all on the same camellia bush.
And this is what I meant about the buds. This is a corner of one that hasn't bloomed yet. Look at all of those buds! It's a great year for camellias.
