This is very close to what Luther Burbank attempted back in the late 1890's. Though his grafting wasn't as artistic as this example. His rational was maximizing the number of test hybrids in a minimum of physical space. One line from the text captivated my interest.
in spring it reveals a stunning patchwork of pink, white, red and purple blossoms, which turn into an array of plums, peaches, apricots, nectarines, cherries and almonds during the summer months
This is very important to me because I've attempted something like this, already grafting peach, necturine, apricot, almond, and Japanese plum on one single tree. My personal best though is only 5, not 40, but I was doing whip grafts, not bud.
The one single tree I've not grafted yet is cherries, simply because I alway's assumed you needed to graft a cherry scion onto a cherry seedling. Sprouting cherry pits is something yet to be successful for me, hence no cherry seedlings to graft.
But, I see this intriguing sentence that suggests cherry scions will graft onto other
trees, which I never tried. Well, a new
project to work on!
