Myrobalan 29C

For anyone curious about what Myrobalan 29C fruits are like, here you go. I had a graft that died so just let the rootstock grow out for a few years to see what it would produce. And the fruits aren’t bad, actually. They’re grossly bitter unless allowed to fully ripen, at which point they have a very “fruit punch” flavor. Pretty much exactly like what you’d get from a generic jukebox flavor. This isn’t really a recommendation since I think there are a lot of way better plums out there (Lavina, Purple Heart, Hildreth, etc.), but not bad. It’s a great rootstock too!

When you say “bitter” do you actually mean bitter or do you mean “sour”? Bitter would surprise me for a plum, sour would not.

Examples: Lemon=sour, grapefruit=sweet/sour+mild bitter, dandelion greens=bitter

Bitter. And yeah, it was unexpected and weird.

That’s cool to note. Going from bitter to fruit punch is a nice transition. Thanks for sharing this info. I’m always eager to learn what types of fruit would be produced on various root-stocks if left ungrafted!

@SMC_zone6 Do you have a picture of the actual tree to share? I’m curious to how it compares with a seedling myrobalan. Thanks

I’ll try to remember to take photos next time I’m at my orchard. I’ve turned it into a multigraft, though, so not sure a picture will be much help.

Thanks, even if there’s a couple original branches to look at. I also created a new thread to see if anyone could identify my seedlings:

Help identifying myrobalan cherry plum-like seedling

Does this tree have huge thorns on it? I think I have a few myro rootstock in the ground but am having a hard time making a distinction between them and p Americana (they’re only little trees at the moment)

Yep. Thing’s like a porcupine.

This is interesting thank you for the info on Myro 29c. My great great grandfather is the man who discovered this rootstock around 1920 in Marysville, CA. His name was Marion Gregory. He started the cling peach industry in Northern California using this variety as a rootstock in his nursery sales. He later moved to Burbank, CA and opened a nursery called Gregory Bros which later became Gregory and Son.

He moved to Brentwood, CA. Not Burbank. Sorry
