blackberry cultivar?

[chocolatechip]

hey,

i've got a blackberry bush which i acquired when i took over an allotment.. i know it's some kind of blackberry, but it's certainly not a normal bramble..

the thorns are thinner and sharper.
the leaves are completely different,, see picture..
the flowers are pale pink. see picture (it doesn't look pink, but they are)

the blackberries themselves are large, and delicious. mmmm

can anyone help, or is it just some kind of cross breed..





thanks

Looks very much like Rubus lacinatus (Cut-leaved Bramble).

Its a garden cultivar - I reconise those leaves from one we had in our garden when I was a kid, but never seen since.....

I'd agree, I've seen it a few times in the wild.

My mum and dad have the cut-leaved variety 'Oregon Thornless' in their garden and every year there are cut-leaved seedlings that pop up in various parts of the garden but with sharp thorns. These are just pulled out but they must be back crosses with the wild ones on the railway line nearby.

that definitely looks like the one.
it does produce excelltent fruit.. unfortuanetly i have given up my allotment, however i kept a part of the plant, and it is growing well in my garden.... but i think i'll be only getting a few fruits this year
