Hybrid Cinquefoil - Potentilla anglica x reptans = P. x mixta

Description

Usually has flowers with four yellow petals, though sometimes five. The achenes are all sterile, the leaf petioles are often over 5 cm long and mostly the same length for the full length of the shoot, sometimes rooting at the nodes.

Hybrids between Potentilla anglica and Potentilla reptans and between Potentilla erecta and Potentilla reptans occur (the latter is P. x italica).  Stace (4th edition) states that these two hybrids can only been told apart by chromosome count. 

Similar Species

Identification difficulty
ID guidance

Some flowers with 4 petals like Tormentil, but leaves with 4-5 leaflets and longer petioles, which are are same length along the stem from lower down to apex.  Very similar to Trailing Cinquefoil, but sterile, so the old flowerheads have few or no achenes containing seeds
