Nanking cherries?

Just want to confirm that these are Nanking cherries before I go turning them into jelly... vigorous, hardy, early-blooming bush about 8 feet tall. They taste more like grapes than cherries, and have a small round pit. This year I beat the birds to them.





(Pic is the volunteer in the shade, not the main bush in the sun... doesn't seem to mind either situation)

I would like to know if there are some of these trees in Australia...

Looks like my nankings (prunus tomentosa) I agree.

Cool, then I'm not imagining things

I suspect it would put up with anything but wet feet -- mine is unfazed by temps ranging from -30F to +100F and doesn't mind being quite dry (at a guess, the roots are probably deep and invasive) but makes more fruit with some water. The one in full sun looks better but the volunteer in full shade, tho leggy, has more fruit (albeit slower to mature and less sweet). It's naturally bushy but you might trim it into a small tree or hedge. It blooms profusely in late March (it even beats the crocuses) and is evidently self-fertile.

Going to try growing a few more from seed, but I'm guessing it's not the best germinator or I'd have them everywhere.
