Only usually :-)

This came up, and someone referred to suckering blackberries, which
I said didn't happen. Well, the other poster was certain, so I looked
it up. I wuz ronk. There are UK (sub-)species that spread by suckers,
like raspberries, don't tip-root, and are common on acid soils.

Section suberecti, if you are interested, whatever that is called
nowadays.


And Japanese wineberries are, fide Wikipedia, tip-rooting raspberries.
(I had intentionally restricted the scope of my statement, to avoid
such quibbles.)

Thought they were a different species. Do you mean that they're in the
raspberry side of rubus? Or are they simply a subsp?
