Take a walk outdoors at this time of year and you’re likely to come home with some of these stuck to your clothing.
These tiny burs are the seed pods of agrimony (Agrimonia eupatoria), a plant native to Europe that was brought to North America for its herbal properties. (See Mark’s comment! This species doesn’t occur locally but we have similar natives.)
Though the burs look wicked in this close up, they’re actually small and rather weak. Compared to burdock they’re only slightly aggravating.
