No shortage of trees that produce fruits and nuts exists across the United States, although some distinct species of trees are in peril from certain afflictions. Fruit and nut trees typically lose their leaves in the winter and then grow new leaves the following spring. All produce some type of flower that eventually turns into the fruit or the nut of the tree. These varied kinds of trees have differences in terms of their size, geographic location across the country and in other regards.
Fruit trees such as the southern crabapple are among the 25 native types of apples alone in the United States, all members of the Rose family. In addition to that, there are multiple kinds of cultivated apples as well. Plums and cherry trees species include the Canada plum, wild goose plum, American plum, pin cherry, bitter cherry and chokecherry. Cultivated varieties of citrus fruit include species such as oranges, limes, pineapples, bananas and grapefruits that exist in warm climate states. The nut trees also have a wide array of types, from the chestnut tree, hickories and walnuts to the American beech.
Native fruit trees are normally smaller than nut trees in the U.S. A tall apple tree is one that is around 30 feet high, with plum trees in the same height range. Cherry trees are some of the taller fruit trees, with the black cherry, for example, growing up to 60 feet tall. On the other hand, the black walnut tree exceeds 100 feet in some cases, many types of hickories grow to that size and the pecan tree may be close to 140 feet tall.
You will find different kinds of nut trees in various parts of the country. Such is the case with the assorted types of walnut trees. Black walnuts are in most of the East as is the butternut, while more localized types like the Arizona walnut and Hinds walnut have much smaller distributions in the West. Likewise, fruit trees have ranges based on species. Crabapples are a good example, with the southern crabapple located in the Deep South, the prairie crabapple in the Great Plains and the Oregon crabapple growing only on the Pacific Coast north of California.
Identifying a particular fruit or nut tree involves careful observation of many facets of the tree as its leaves, the color and texture of the bark, the height of the tree and other features. For instance, the persimmon tree will be about 50 feet tall, growing in the southeastern part of the country, have green oblong leaves that fall off in winter and produce an orange fruit about an inch and a half wide.
Fruit and nut trees are susceptible to a selection of disease, many of them caused by fungi. The American chestnut is one kind that is at the mercy of a terrible blight introduced accidentally from China in the early 1900s. It has wiped out all mature chestnuts and kept any that sprout from their stumps from growing taller than 25 feet. Fungal maladies afflict fruit trees to, with some such as rust causing leaves to drop off apple trees prematurely.
