Common burdock (Arctium minus) regularly infiltrates lawns and fields in central MD. I first noticed burdock in our yard last year, and once I knew what to look for I saw it everywhere.
This year, we cleared out an area in our yard choked with weeds and overrun by poison ivy and honeysuckle. In the midst of this mess, I uncovered several second year burdock plants. I carefully marked them with flags so they wouldn’t “accidentally” get mowed with the other weeds.
Since burdock is a biennial, these burdock plants were already large and have since grown even bigger. They would make nice show pieces in an edible landscape, if they weren’t randomly located in our front lawn! In late spring, the second year roots are too big and tough to harvest for food. Plus, with the size of these plants I can’t fathom how big the roots must be. When we harvested first year plants for roots last year, we invested a lot of effort for the amount of food we got out of it.
(I apparently never posted about eating burdock roots, oops? Rest assured, the julienned roots nicely complemented the other flavors in a stir fry.)
Like other biennials, second year burdock sends out flowering stalks. Before they flower, the immature stalks can be harvested and many sources said they were the best part of foraging burdock – no digging required! Timing is everything; as you wait, the stalks get bigger, but as they grow they become more tough and bitter.
Apparently, when you topple the flowering stalk, the burdock plant sends up a new one to try producing flowers and seed. I’ve read that one plant can produce as many as three harvests of immature stalks. Sounds like a great food source to me!
Each flowering stalk had several side-shoots as well. I wasn’t sure if they were worth collecting too, so I harvested everything to be sure. Since this little experiment – just a few days ago! – I read that if a burdock stalk has laterals, it is already past its prime. Oops again?
Burdock leaves allegedly have medicinal properties, but I know even less about foraged medicine than I do about foraged food! I just composted the leaves I cut from the stalks.
Honestly, I struggled to efficiently and quickly peel the stalks. I used a paring knife and kept working until I only had the smooth insides. The fibrous outer portion seemed to take forever to clean away.
The smaller stalks from the side shoots were easier to peel, but had a much smaller core for the amount of effort required to get to it.
I eventually gave up on peeling these smaller pieces.
Also, the burdock ended up staining my hands slightly brown. None of the resources I’d researched on burdock mentioned this side effect. Not as bad as black walnut, mind you, but still noticeable. You can just see the stain on my fingers in the pictures above.
At long last, we had a side-dish-worth of burdock stalks. It didn’t add up to much!
I microwave-steamed the stalks with two tablespoons of water for six minutes, stirring partway through. I dressed the stalks with butter and salt. The flavor was OK, but nothing remarkable. Certainly not worth all the attention they garner as a wild food. One book I read compared the flavor to cardoons, but I have never eaten a cardoon – I actually had to research what a cardoon even is – so I cannot offer an opinion there.
One of my kids bravely nibbled a bite, and claimed it tasted like artichoke hearts. And so it did! In this family, steamed artichokes are enjoyed with mayonnaise – hey, don’t judge! – and indeed we all enjoyed the burdock stalks a lot more after dipping them in mayo.
The real question is: would I do it again? I only harvested what I thought we would eat, so several stalks linger in my yard. Plus, the three plants who sacrificed their stalks ought to produce new ones as well. Maybe I will try slightly younger stalks next time… stay tuned!
