Not sure if this is of any worth to you or not, but I have seeds of jumbo thornless blackberry. Natchez is the name if my memory serves me right. I also have collected seeds from the wild blackberries growing on my property.

I'll take a pass on those, thanks for the offer though!

I have :

Darrow -- very vigorous with large berries and large thorns.

Black Satin -- thornless, smaller but prolific berries.

Both have done very well in my zone 5 garden (Iowa).

I need to move the patches as they are getting too much shade and taking up too much space. I am planning on waiting until September though.

I am interested in Autumn Joy and hops.

trovesoftrilliums,
that sounds like a great trade. I will mark my calendar and get in touch in september.

anyone else thinning a named blackberry patch?
