I also read about being able to sub them for blackberries in a blackberry

the whole fruit or just the inside!

The inside. And it substitutes for blackberry only if you find
supermarket foods too strongly flavoured. Forget it.

Yes, you can grow P. edulis from seed.

On another point, Cambridge has had a summer that has been equal
parts warm and miserable, like most other places. P. edulis hasn't
a hope in hell of surviving the winter unprotected, even if dry,
as we get mild frosts even in mild winters (-5 Celcius last year).
I am trying P. incarnata, which can take frost, but finds our
summers too cold for it :-(
