strange blackberries.

[yorkyman]

I have a long stretch of blackberries growing along my fence in part of my garden. The young berries are just forming, small, hard green ones.
But just recently I've noticed a different type of berry growing amongst them.
They are in clusters and look and taste exactly like loganberries.
Is it possible that a bee or an insect has visited a raspberry patch then
visited my blackberries, causing a cross pollination.

Try and trace the berries back to the root. It won't be a different berry on the same plant as the blackberries, but may well be a self-sown hybrid that has "grown itself" in the row. If you like it, dig it up and move it to it's own patch.

Thanks for that, seems I've got a new plant without having to pay for it.
I'll leave it where it is, too much disruption to move it.

It probably arrived via the back end of a bird, irrespective of source. My large and intentionally semi-wilderness plot has currant, gooseberry and cane fruit plants scattered across it (plus innumerable wild fruits), and definately not from my own soft fruit as they are permanently bird-proofed and a good distance off in the main.
