What are commercial plums?
Are the standard red and black plums you get in the store any of the varieties for the home orchard? I've noticed that many fruit varieties grown in the home orchard are frequently also commercial varieties--Red Delicious, Honeycrisp, Bing & Lapins cherries, Bartlett Pears, etc.
But, I've never seen the black plums identified. Despite the usual awfulness of store-bought fruit, the black plums are truly delicious if picked ripe enough to actually ripen before they go bad after purchase, to a soft, juicy, and very aromatic perfection!
The descriptions of the plums offered by the various nurseries don't seem to match commercial plums, and the pictures also don't resemble the commercial ones.
