Summer

About the end of July you start to see people stopped by the side of the road, poking around in the bushes. No, they're not doing anything strange or unseemly; they're picking wild blackberries! Late summer is definitely blackberry season in Northern California. And what's best is that these sweet little fruits can be had for free just about anywhere, if you're willing to risk stained clothing from all that blackberry juice, as well as the occasional wound from the blackberry's thorns.

There is a native variety of wild blackberry, the California or Pacific blackberry (rubus ursinus), but that's relatively hard to find these days, being supplanted by a non-native species, the domesticated Himalayan or Armenian blackberry (rubus armeniacus). This variety, fast-growing, invasive, and considered a pest by many, was introduced as a commercial cultivar in California in the late 19th century, but like so many non-native species prevalent in the state today, it got loose and spread all over the place. An easy way to tell the difference is to look on the underside of the leaves. The California variety is green, whereas the Himalayan is white.
