Foraging in Minnesota: Wild Plums

Read More Wild plum foraging

When it comes to foraging, nothing says “end of summer” like wild plums. During that late August/early September time with cool mornings and moderately warm afternoons, I know without looking that American and Canada plums are ripe. 

Prunus, spp.

Most people don’t know it, but Minnesota is home to two species of wild plums. 

American plum (Prunus americana) is by far more common. It prefers upland locations and spreads vegetatively, forming dense thickets. According to reputable sources, it can be found all over the state, but is definitely more common around farmland and hardwood forest openings. 

The other of our plums is Canada plum (Prunus nigra). It is less common, and more fond of shaded surroundings and higher soil moisture. It is more likely to be encountered the farther north you go (you know, toward Canada). 

Telling the two apart is not always easy; it can be more art than science. Still, putting together enough clues should help one make a confident diagnosis. 

First, consider the leaf shape. P. nigra (generally) have rounder leaves, while P. americana’s are more ovate, sometimes decidedly elongated/pointed. Also, americana leaves have a more prominent sawtooth margin. 

Second, consider the location and each specie’s general preferences. Canada=shadier, wetter, northern. American=sunny, drier, southern and western. 

Last, the Minnesota Wildflowers website points out that Canada plum has tiny glands on the leaf stalk, whereas American plum may have glands on the leaf blade near the stalk. Believe me, it can be a struggle to find enough leaves or stems with glands to be certain of their location. However, sometimes it’s a slam dunk. 

Wild plum foraging/harvesting

The Harvest

The window for a plum harvest can vary from year to year, like many other fruits. This year was a tough one, and I believe that was mainly because of the drought. Plums were generally hard to come by. They were often on the small end, and they ripened a bit early, too. The plums that were most ripe on August 19th, for instance, were small and on bushes with yellow leaves (top photo). 

In general, I expect American plums to be ripe around the Twin Cities area to be in their prime in the last week of August through the first week of September. That’s also true for Canada plums I’ve picked in the north central part of the state. But as I said, this year was early. If you don’t want to risk missing out, I’d recommend keeping tabs on your best plum thickets from mid-August onward. 

Wild plums can be tricky to time just right. Picked a little early, they’ll be mealy and less sweet. Picked too late, they’ll definitely seem overripe. When they’re just right, there’s nothing better. Problem is, it sometimes all plays out in a few days. 

In the last couple years I’ve experimented with picking them on the early side and letting them ripen on the counter at home. It works very well if you keep daily tabs on their progress. The trick is to pick them as they get close to their final, purplish stage. Yellow is way too early. Timed right, ripening takes only a couple days. When they feel nice and soft, they’re probably there; it wouldn’t hurt to taste one or two. They should be juicy and sweet. I recommend keeping them in a closed plastic container to keep the fruit flies away. 

Tasty, tasty plums

Plum jam is a great way to use them if you don’t eat them all fresh. A couple years ago we made a batch of jam for the first time. It was….okay. This year we tried using plum pulp with pin cherry juice, and the result was better. The ratio was about 3 parts plum to 1 part cherry juice. The plum texture was present, but cherry flavor came through nicely. 

I’ll continue experimenting similarly in the future, because I believe that like juneberries, plums make a good main ingredient for mixed fruit jam. I suspect it could be a good use for leftover amounts of chokecherry juice, for instance. Maybe I’ll incorporate some apple from our tree somehow. 

What is your experience making plum jam? Any suggestions or crazy ideas you’d like to share? Leave a comment below!

Foraging in Minnesota: Sand Cherry

A couple days ago, my daughter found a single cherry. I could not have been more elated. 

It was our first Sand cherry. We’d been searching hard for two whole days, covering almost 10 miles on foot, in three distinct parts of Minnesota. The triumph was not so much the harvest (ultimately a couple dozen cherries) as it was the successful conclusion to our foraging quest.

Do Something New: River Smallmouth Float Trip

Read More

I recently took a day trip on the Mississippi to do some fishing. It’s something I hadn’t done before, but had been considering trying on the many fishable rivers in the area. 

It’s good I did, because it will probably stand as one of the highlights of the entire summer. To tell the truth, the plan was so simple, it really couldn’t fail: just me, my kayak, the river, and any smallmouth bass that were in the mood for a tussle.

Yellow Bass of the Fairmont Chain

Read More

I was on the phone last night with an old Minnesota fisherman. He asked if I’d done anything interesting lately. I said, “See if you can guess. What are yellow with black markings, plentiful, and taste good when they’re battered and fried?”

“Bananas.” 

“Yeah, well, okay….here’s another hint: they wiggle and flop when you throw them on the ice next to your sled.”

“Puppies?”

“What? No! I’m talking about yellow bass.”

“Huh. Never heard of ‘em.”

No kidding.

BWCA Entry Point 25: Winter Camping and Fishing

Read More

For years I have dreamed of camping and ice fishing in the Boundary Waters Canoe Area Wilderness. Biting cold and slush-laden lake tops have kept me home the last two winters. That was fine; I’m not one to press my luck. But the warmer-than-average weather we’ve enjoyed lately had me itching to get at it.

Entry Point 25, with walleyes in Newfound Lake and brook trout in Found Lake, was the perfect setting for my introduction into winter adventuring. Little did I know, however, that introduction would come with a sobering peek into my own psyche. Continue reading “BWCA Entry Point 25: Winter Camping and Fishing”

The Year of Untouchable Bucks

Read More

Hanging some antlers on the wall is a dream that sparkles in every deer hunter’s eye. Unsurprisingly, big bucks dominate deer hunting marketing and media. I will admit I’m not immune to the images and hype.

But at this time in my life, my main priorities each deer season are observing tradition, pursuing new experiences, and doing all I can to secure meat for my family. My 2020 deer hunt embodied those three as much or more than any other, spread across two weeks and three distinct settings. Continue reading “The Year of Untouchable Bucks”

Trip Report: Bottomland Paddling and Sanborn Canoe

Read More

After my incredible deer hunt in the Mississippi bottomlands of southeast Minnesota last season, I’ve been hot to find similar territory for future excursions. And since the Upper Mississippi River National Wildlife Refuge contains almost limitless opportunities for somebody with more ambition than sense, it was an obvious place to start.

Foraging in Minnesota: Blackberries

Read More

It’s blackberry season. While I sit here typing this out in mid-August, I have a hunch there are literally tons of them out there going unpicked. And while not every year is good for blackberry picking, we’ve had good rainfall in 2020, which is a good sign. It was the same last year, when I literally picked gallon after gallon throughout most of August and into September, within a mile of my home.  Continue reading “Foraging in Minnesota: Blackberries”

Foraging in Minnesota: Hedgehog Mushrooms

Read More

Yesterday I found my first hedgehog mushrooms of the season. It was on a short outing with my daughter; she was after raspberries and I wanted to follow up on the sudden burst of mushroom activity in the yard. I suspected some edible mushrooms would be available, mostly chanterelles and lobsters. Those were good finds, but I hollered out loud when the first few hedgehogs appeared on the forest floor- they are among my most favorite mushrooms to eat.

Foraging in Minnesota: Dwarf Raspberries

Read More

Every year about this time there is a lull in the foraging season here in Minnesota. The early season has passed and the frenzy over morels, fiddleheads, and ramps is over. The summer mushrooms and berries really haven’t started. However, while raspberries, blackberries, thimbleberries, and other members of the Rubus clan have yet to even finish blooming, their little brother is here to take center stage. 

Enter Dwarf Raspberry. Continue reading “Foraging in Minnesota: Dwarf Raspberries”
