cherry trees and cherry blossoms are two different trees
Do you mean "ornamental" cherry trees and "fruiting" cherry trees? A "cherry blossom" (or "sakura") refers to the flower of a cherry tree, usually of the "ornamental" variety. The article seemed fine to me.
Both kinds of trees have blossoms. Granted, people do call ornamental cherry trees "cherry blossom trees" ... but, technically speaking, a "blossom" is literally the flower of any stonefruit tree.
