Trailing Tormentil - Potentilla anglica

Description

Similar to Tormentil (Potentilla erecta) but with persistent basal leaf rosettes and with the stems rooting from at least some of the nodes. Leaves often with 5 leaflets, flowers larger than Tormentil (Potentilla erecta), 14 to 18 mm with 4 or 5 petals, solitary or several together. Hybridisation occurs and specimens may need to be confirmed by an expert.

Similar Species

Potentilla reptans, Potentilla erecta and the hybrids Potentilla x mixta and Potentilla x italica

Identification difficulty
ID checklist (your specimen should have all of these features)

Some flowers with 4 petals like Tormentil, but leaves with 4-5 leaflets and longer petioles, which diminish in length towards the stem apex.  Very similar to the sterile hybrid, but Trailing Cinquefoil is fertile, so the old flowerheads have achenes containing seeds.

Recording advice

Xestophanes brevitarsis

Xestophanes brevitarsis is a gall wasp that causes galls to form on Tormentil  and Trailing Tormentil. Galls are usually found on the aerial stem or sometimes at the root and take the form of rounded swellings, 2 to 3 mm across, often several in a group and sometimes coalesced. They are green or pink at first, becoming brown and hard.
