Where can I find Red Plums?

Red plums can usually be found fresh in farmers’ markets and better groceries when in season. Plums are soft fleshed and do not travel or store well.

Are Black Plums Dark Inside?

One exception, commonly found in U.S. markets, is the Black Splendor Plum which has dark burgundy flesh. 

What Does it Mean if a Plum is Red Inside?

Anthocyanin in plums

If a plum is red inside, it means that it has a high level of Anthocyanin. Anthocyanin is a family of ant-oxidant flavonoids reported to have a wide range of health benefits, including the prevention of inflammation, cardiovascular illnesses, cancer, neuronal diseases, and diabetes. 

In plums, as with many similar fruits, it is also indicative of high sugar content. One of its main constituents is glycogen, a natural form of glucose used for energy storage.
