Tree of 40 Fruit the New York State Agricultural Experiment Station, which was closing due to funding cuts. He began to graft buds from some of the over 250 heritage varieties grown there, some unique, onto a stock tree. Over the course of about five years the tree accumulated branches from forty different "donor" trees, each with a different fruit, including almond, apricot, cherry, nectarine, peach and plum varieties. Each spring the tree's blossom is a mix of different shades of red, pink and white. , Van Aken had produced 16 Trees of 40 Fruit, installed in a variety of private and public locations,
Fruit tree pollination a pollinator tree. Working from an old Spanish variety, "Tuono", researchers in 2008 started making available new self-fertile varieties that more closely match the qualities of the popular "Nonpareil" almond—including varieties "Lone Star" and "Independence". While self-fertile trees do not require pollen from a second tree variety for fruit / nut set, they still depend upon insect pollination for good production. Almond growers with self-fertile almonds report excellent nut set with half (or less) the number of bees in the field. Like apples, pears are self-incompatible and need to attract insects in order to be pollinated and produce fruit. One
