Ramble, there is no truly dwarfing plum. About 3/4 size (semi-dwarf) is the most dwarfing you can get. So its not a huge difference. Raintree sells several plums on semi-dwarfing rootstocks if you want to look at another source.

From my experience of those I would put Superior and Red Ace at the top. Many plums are difficult to get to produce or are disease magnets. Those two have been good for me so far and they are different enough in flavor. I think their ripening time is a bit close though. Shiro is boring. Santa Rosa plums are too disease-prone as is El Heart. Methley is not the best tasting but otherwise is excellent. I have no personal experience with the rest.

Scott,

Very, very helpful. Thank you.

Superior you say is better than Methley. My main decision is between these 2, with Weeping Santa Rosa a possibility.

Stark claims its dwarfs grow to 8-10 ft. They have semi-dwarfs that grow to 12-15 ft. So they say.

Those heights are way off I would say. The only rootstock I have seen which truly dwarfs plums is Krymsk 1 and it is very uncommon. I have some and have had trouble getting things growing at all on it, so I doubt any nursery would want to use it.

Stark says it uses "redleaf seedling" rootstock. Would that dwarf to 8-10 ft.?

Stark says they now have Redheart.

So, still looking for others opinions for best among: Superior, Methley, Ozark Premier, Redheart.
