One of the well-known wild plums in the Sooner State is the sand plum, also called the Chickasaw Plum, Cherokee Plum, or Sandhill Plum. Wild plum bushes can be seen growing inside and on the borders of oak tree forests. The bushes have crooked trunks and branches, and spikes. Their sizes vary from three to five yards tall to one to four yards wide.
American plum trees are native to this continent. The berries are way smaller than the plums sold at supermarkets. The size of one berry is about half of an inch by a quarter of an inch (probably, it is as big as a cherry.) Wild plums can be green to yellow or red to purple.
The plum trees spread well in the forests and fields, and they can become invasive. The plum tree flowers attract a lot of birds, which eat the berries and drop the seeds.
According to www.heppy.org, there are 15 sorts of wild plums in the United States. American wild plums can be eaten fresh or good for making jams, jellies, and drinks, including wine.
