Joseph Hamilton Lambert the formerly productive trees. Lambert introduced new horticulture methods that in two years restored the health of the trees and again allowed them to produce "mammoth" crops of apples. Lambert became the sole owner of the orchards, which are notable for being the first to produce cultivated fruit in Oregon. Lambert developed what became known as the Lambert cherry, by grafting a volunteer seedling, found in 1848 under a Napoleon cherry tree to the rootstock of a May Duke cherry. The crown of the tree died in 1880 and a new tree grew from its roots that was not a
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
