Hi,
Has anyone used Klamath Plum (Prunus Subcordata) as a rootstock for any other Prunus? If no one has used it as a rootstock, I think someone should try it. Klamath Plum is a PNW native Prunus, so it would certainly be a rootstock well suited for the area. I just thought it might make a good rootstock as it is native, and personal experience with this species leads me to believe it to be a vigorous plant. Also, for those with clay soil, I used to live next thriving thicket of Klamath Plums that grew choice plums in the nastiest black clay soil Oregon has to offer.
The plant itself is quite lovely, but I do not think it is worth growing other than for ornamental purposes. It fruit is small and tart, I actually like, but it almost more pit than flesh. I suppose if you had enough of them, you could make some preserves.
I just thought I would ask and share my thoughts.

Oh boy that sounds like a fun experiment. How large does this prunus get? Have you searched on Google? I am also curious if anyone has done this.
That plant is said to grow in only four counties on earth:2 in Oregon, 2 in California. There is a winery that makes a very fine wine out of it. Stringer's Orchard? Just over the border from Lakeview, OR in New Pine Corner.The trees are about 10 feet tall at their orchard. I would imagine that it would get diseases in the Willamette Valley.

I've got just the opposite of what the OP said. Mine is a select subcordata mounted upon a probable salicina seedling that sprang up from compost years ago. Have had it as a single tree in its permanent position for at least 5 years, and no hint of a flower, even this year. Seems happy and healthy otherwise, though.
The deer have done a nice job of keeping it in a tree form instead of shrub form. Wire fencing hoops keep the bucks from destroying such with their antlers.
