"I think I told you that Beauty of Leafland was from double white altai pollen. Actually it came from seeds when I used mixed pollen on all the roses. I had forgotten that pollen of Haidee was also in the mixture and concluded that Dble Altai was the only one that could be the pollen parent. The waxy petals and tall growth make me think now that it must have some R. Laxa strain in it. Incidentally I got more interesting seedlings when I gathered pollen from every rose that could be a good parent and mixed it all in one dish. It is also time saving but you have to guess what the pollen parent was and in some cases seedlings are so different from both parents that even guessing is impossible. But you might make some crosses that you wouldn't think of by this method. I intend to keep track of the pollen parent in only a few cases this summer. I also have many roses that I want to cross planted close to each other so the bees can do the hard work."
