Plant Identification,Who Knows Plums?

Recommended Posts

amh

I know plums aren't tropical, but I need some help with identification. The area is the south eastern Edwards Plateau.

I found what appears to be 3 plum trees growing in my backyard; I believe they are Prunus mexicana, but I could be mistaken. Does anyone have an ID?

I've never seen pictures of the mexicana seedlings, but there are lots of various wild plums in my area. The leaves are too ovate for Prunus munsoniana and Prunus rivularis.

Can see what you mean.. Leaves didn't look right for P. americana, which supposedly also occurs in a few spots out there. Something makes me think the leaves on Mexicana might be softer.. or have a sand papery texture too rather than a smooth or shiny feel/look, like other Prunus..

I have P. americana, but they are not of fruiting age yet. There is a huge variation in P. mexicana leaf shape from the pictures that I see online. The leaves are fairly rough and there is a large wild plum growing about 400 feet away in a different yard. I haven't been up close to the tree in about 25 years, but it is at least 20ft tall.

Also, do you have any experience with Prunus subcordata?

I have some seeds stratifying right now and was wondering about the plants vigor.

Any experience with Prunus ilicifolia?

Familiar w/ that species.. but mostly pants observed in habitat.. Have heard different info. regarding germinating seeds.. Some say they're easy, other info says germinating them can be tricky.  Very tough plant though.

I've grown them in the past, but they died while in pots, I think I had bad soil. I did stratify the seeds and had a very high germination rate.

I'm mostly curious about the cold hardiness. Some sources say 10-15F and the next will say 20F at the coldest.

I'd say closer to the 10-15F, maybe lower.. Description from Las Pilitas nursery says young plants, say 1-2 years of age, can be killed by temps below 20F, but older plants can supposedly survive temps down to 0F, maybe colder..
Grows in numerous areas that would be considered 8B, maybe colder in a few locations in it's range ..so the cold tolerance sound correct, imo.
