Before human interference, plums were smaller. They were closer in size to grapes, as opposed to what they’re closer to today, which is apples. It’s said that plum fruits may have been one of the first fruits domesticated by humans. According to Prime Scholars, “plum remains have been found in Neolithic age archaeological sites along with olives, grapes, and figs.” Humans cultivate plums in all temperate climate countries of the world. These Neolithic plums weren’t the plums we see today. There is one plum that hasn’t made it to modern days, and that’s Murray’s plum. It is scientifically known as Prunus murrayana and was found in Texas at the Edwards Plateau in 1928. No one has seen it since then, but if you’re feeling adventurous, go ahead and look for a thorny shrub 17 feet tall, with white flowers and red plums with white dots. A little bit of detective work never hurt!
