"Blackberries for everyone: Caution may be poisoned" Top 5 Page for this destination Blackberries for everyone Tip by glabah

Blackberries are everywhere in the Portland area, and to a lesser extent all over the northwest. The most common type was introduced and is now considered an invasive species because they take over just about any open space and to a lesser extent forest land.

Therefore, you can pretty much find them everywhere. Most commonly they are around in late summer, but the exact season depends a lot on the amount of rain and average temperatures during the year.

The vines are easy to spot: they are the long thorny vines that stick out of just about any pile of weeds and brush in wild lands around Portland.

However, if they are beside the roads it is quite possible that they have been shot with any number of assorted poisons by the highway department to kill them. You do not want to eat those, unless you are certain that they have not been sprayed recently.
