Picking wild berries in Minnesota

Walking through any Minnesota woods, I compulsively search the ground looking for the telltale signs: small-toothed leaves at the edge of a path, a glimpse of red at just the right angle. Score!

I eagerly move in for a few gentle plucks and hold up some wild strawberries. Their flavors burst out, concentrated and tangy, as if to overcompensate for their diminutive size.

If strawberries are past their season, my eyes move upward scanning for one- to two-foot shrubs polka-dotted with blueberries. They drop beautifully into my bandanna, hastily knotted into an extra pocket for occasions such as these.

July is often bonanza time for finding wild berries in Minnesota. Strawberries usually show up by mid- to late June, followed by blueberries in early to mid-July, and a parade of lesser-known bounties. Good news if you're late to the foraging party: This year's winter-that-wouldn't-quit delayed the harvest.

"They are at least two weeks behind," says Theresa Marrone, author of "Wild Berries & Fruits Field Guide of Minnesota, Wisconsin and Michigan" (Adventure Publications). That includes berries in the Twin Cities and central Minnesota, along with the North Shore, where blueberries and thimbleberries were blooming in late June.

That could bring a delicious bounty by the end of the month — especially along paths and the edge of forests where you can still find thickets of blackcaps (black raspberries) and wild raspberries that, once plucked, catch the sun like rubies.

The trick, of course, is not only good timing, but knowing where to find the fruit. Passionate berry-pickers are as willing to divulge their favorite patches as anglers are their secret fishing spots, says Steve Robertsen, interpreter at Superior National Forest's Tofte office. Experts like Robertsen, thankfully, are more forthcoming. Here are their tips:

Berries are among the first plants to regenerate in areas recently cleared of trees or recovering from a forest fire.

In the metropolitan area, it's best to avoid city or regional parks (where picking usually isn't allowed). Opt instead for trails in the Minnesota Valley National Wildlife Refuge or along national parkland hugging the Mississippi.

When visiting a state or regional park, hit up the park or forest rangers for advice on what's ripe, where to find berries, and advice on making sure you have the right plant. Take a map, too. Smartphones or GPS signals can fail on remote trails or forest roads.

While it's tempting to pull over and feast on easy-to-spot roadside berry patches, Robertsen advises avoiding them because they may be sprayed with chemicals to control invasive species.

Look beyond the usual fruits for unique and unexpected flavors: currants, chokecherries, pin cherries, high-bush cranberries, elderberries and more.

"Serviceberries are all over the place, but people don't know much about them," she says. They taste (and look) similar to blueberries, but with a slight almond flavor. If you're near Minnesota's northern border, you'll find shops with tins of Canadian Saskatoon jam.

Robertsen counts thimbleberries among his favorites. They're larger than raspberries, but also thinner, more delicate and quick to spoil. That gives you the perfect excuse to eat them immediately.

The nature-friendly guideline is to never pick more than one-tenth of what you find, Robertsen says. That leaves enough fruit for birds and animals. And while state parks, federal refuges and forest lands usually welcome pickers, fruit may only be picked for your own consumption and not for resale.
