I’m in the south sound area of the Pacific Northwest. I’ve had Brooks plums in my garden for about 30 years, they do amazingly well in our climate. They are an offshoot of the iltalian prune, but are 4 times the size and amazingly sweet with a honey like flavor. They are great right off the tree, dried or canned. I’ve made fruit roll ups out of them for years. My wife started making pies out of them, absolutely incredible, theflesh stays light colored and firm like a peach.
If you plant a 5’ tree it will start producing in about 3 years. It start fruiting heavier after about 5 years and the flavor will improve as it gets older.
Self pollinating. And you’ll havta keep an eye on your neighbors, but we get so many I don’t mind if they help themselves!
