"My best yellow rose, the one you saw last July, puzzles me. It is too good for an Altaica-Harison's Yellow cross, with a long bud suggesting H.T., a perfect form of half-opened flower, and the scent of the tea rose. the cross that produced it was made in 1938, and I don't remember using any yellow HT pollen then. Besides, if a yellow HT was in its ancestry, it would not be 100% hardy (as it is), and if Persian Yellow was the parent, surely it would not be completely fertile (as it is), or have an agreeable scent. It's a mystery, but it's a wonderful rose. I named it Hazeldean, - the other name, Annie Laurie, having been used before."

"I have several very new roses of which I am proud. One is a seedling with single yellow flowers to pollen of Hazeldean. It is double almost as double as Hazeldean and has normal pistils, not the aborted type that Hazeldean inherited from Persian Yellow. It blooms a week earlier than Hazeldean, which means more time before the curculio appears. I'll name it LOTHIAN.
Another is a single yellow Altai type, the deepest yellow descendant of Hazeldean I have ever seen. I don't doubt that it's fertile too. It will mostly replace YELLOW ALTAI, which has hips and seeds, but the seeds refuse to germinate. I have named it LOMOND. I figure that Scotch roses should have Scottish names.
Another new rose is a substitute for Austrian Copper a single that blends red & yellow in a very attractive way. It is (Gallica x laxa) x Hazeldean. It won't be fertile, but, unlike Austrian Copper, will be free of blackspot, and probably a bit hardier."

"I'll enclose some further rose seed for you to experiment with. It will be Bertha x Hazeldean. Bertha is a rugosa-blanda hybrid, F2, that leans to rugosa, but grows nine feet high. Hazeldean is my prize yellow rose, altaica x Persian Yellow. Thus the seeds will give you triploid roses. Stratify them at once."

"I had a letter a few days ago from the Meilland Nursery in S. France, to which I had sent budwood of my Hazeldean rose 1 1/2 years ago. The letter said that "Hazeldean rose is already in commerce." This means that someone to whom I supplied it, with the promise they'd kept it to themselves, has cashed in on it. Either that, or the plant at the merit trials in Morden was robbed of budwood by some visitor from Holland. Anyway, it seems that I have been done out of some thousands of dollars. Of course, I should have sold the rights to Hazeldean many years ago. I originated it about 1943."
