I found Prunus subcordata growing at 2,300 feet on a north aspect in the eastern Siskiyou mountains. A large clump (15 feet in diameter) was growing under high shade of mature Douglas-fir and ponderosa pine. This particular clump had oval to round leaves with toothed margins and a few 1" diameter plums. An elegant little tree.

I took a few cuttings but they did not strike. I intend to try again.

As to increase our diversity on sources, and germination chances, this request.

We try to establish a collection of all possible Prunus varieties, especially the wild ones, as an educational help for our students to show realistic diversity. Some specimens are still missing.

This message is a request for help to find some viable seeds or even better, seedlings with naked roots, from:
- Desert Apricot or Prunus fremontii
- Sierra Plum or P. subcordata
- Desert Peach or P. anderssonii
- Desert Almond or P. fasciculata
- Hollyleaf Cherry or P. ilicifolia
As these are maybe growing in your ... read more

Grows wild in the foothills of the Sierra Nevada, including my front yard, and great grandparents had a mature tree growing in their yard in Magalia when I was a child. Fruit matures to yellow blushed with orange. It's roughly the size of a cherry, perhaps a bit larger, and contains a large pit. Fruit is tart but sweet and I always enjoyed eating them. Not enough flesh to be worth pitting them to can or bake with, but fresh fruit is delicious, though probably and acquired taste.

I have several young trees growing in the vacinity of what appears to be the stump of the parent plant which was likely removed by the prior owner. These are small shrub/trees and the stump has roughly a 3in diameter. I recognize the young trees easily as they sprouted near my grandparent's tree as ... read more
