Here's Rosa davidii. I only have one hybrid from this species so far (with Rosa virginiana), but am using pollen from Rosa fedtschenkoana on it right know. Hopefully next Spring I'll be able to report on offspring from this cross.
In the second picture, I was trying to show how purplish the pink flowers look to me. I'm holding a petal from fire-engine-red 'Home Run' beside a newly opened flower and a day old one.
