The flowers on this plant are bright yellow and are nicely sized for such dense clusters. The cheerful flowers are on medium to tall flower stalks. The seed pods/fruits are also quite pretty. I'd actually NOT cut this back in winter, but instead remove the dead leaves and leave the stalks with the seed pods for winter interest.

The leaves on this plant form in sets of 3 leaves per node (as var. trifoliatum suggests. Tri + foliatum), though it seems that mutations are quite common: sometimes 2 leaves, 4 leaves, 2 leaves fused together....

This plant is not too aggressive in its present conditions (a meadow bed with a few competitors, mainly grassy weeds; soil around 60% good garden soil from garden-store, 40% nearly pure reddish clay). It does not seem to self-seed (will update if I find that it does) and does seem to clump up, but not in a messy way.
