Southeastern, New Hampshire

Norwegian Cinquefoil is the only cinquefoil in New Hampshire with 3 leaflets per leaf.
The leaflets are heavily-toothed and, at up to 3 inches, almost as long as Sulphur
Cinquefoil (Potentilla recta) leaflets. The plant tends to have
significant branching and a fairly dense pack of leaves compared to the
other cinquefoils.
The 5-petal yellow flower has big spaces between the petals and the green sepals behind
the flower petals are as long or longer than the flower petals. It is found in clearings,
roadsides and weedy places. I found it in a field with Oxeye Daisy, White Campion,
Red Clover and Flat-topped Aster.
