John Rivers nectarine is a definite take.
I can finally say that Zard apricot is a take too, as well as Reine des Mirabelles. I'm thrilled by that.
I'm pretty sure Hesse plumcot would have made it too, if the damned Methley/Myro host stock didn't just die out from underneath it. Blast!
My earliest grafts did best. Like you said: "Don't wait for the perfect conditions to arrive. They may never come."
It's a numbers game. Eventually you get some winners.
Today, I looked at a two-year Nancy Mirabelle graft. The thing just grew six feet tall and is over my head now. I remember when it was waist high. Amazing.
