I think those and the little burrs are different species. Galium aparine Vs Arctium minus.

Oh you mean like the cockleburrs you get on things? Maybe more about the size of a small grape, outside diameter?

It's weird, I've only ever noticed those on the west coast.

Cockleburrs? They seem to grow well in the US Midwest (at least about 40 miles west of Chicago.) We also get stick-tights which are much smaller.

As for my "lawn", I mow whatever grows at the highest height I can set my mower. No fertilizer, no toxins. Whatever grows is appreciated. Except thistles, cockleburrs and stick-tights. I have a variety of grasses, American violets, clover, ajuga and lots of other stuff. I also pull portulaca and add it to my salads.
