Flowers on solitary stem arising out of a leaf axil. The first flower arises from the
2nd leaf axil from the bottom (This differentiates Common Cinquefoil from
Canadian Dwarf Cinquefoil (Potentilla canadensis) which has the flower arise
from the 1st leaf axil from the bottom). While this plant can be tall, often times
the stem droops or folds down over other plants.
Leaves are on separate stem from the flower. Leaves are alternate up the stem. They are palmately
divided (all leaflets emerge from same point). For the Common Cinquefoil, the leaf stem is
redish. The stem and leaf petioles are slightly hairy (appressed hairs).
The leaflets have teeth for 3/4ths of their length. (Canadian Dwarf Cinquefoil leaflets have teeth for
only 1/2 of their length.) Some Common Cinquefoil leaflets have teeth for only 1/2 of their length,
but measuring the upper leaflets seems to more consistently show that the teeth run for nearly
3/4ths of their length. The stipules (leaf-like appendage at the base of the petiole/leaf stalk)
are linear-lanceolate and rolled. Plant height: 6 - 20 inches.
