This plant grows in clumps in our front yard. We mow around it because we like the flowers and unlike the pointed leaf tick-trefoil, the blossoms don't turn into snags.

There is a prairie remnant near me that has a fair amount of showy tick-trefoil in it. If I go through there in late summer, when I come out my clothes are just plastered with its pods. It is worse than pointed leaf tick-trefoil, I think. :-) I carefully pluck the pods from my clothes and save them, to be replanted elsewhere.

Edenbrook Conservation Area in Eden Prairie has a good number of these. Have also seen a few on Jim's Prairie, Maplewood.
