Rather Potentilla nepalensis; flowers with darker centre, smaller, leaflets less silky and more importantly lower leaves should have 5 leaflets.

I am confused by this.  You say "taken in the wild" in the UK but Cardiff is hardly "in in the wild" and this appears to a cultivated

plant in a situation that as far as I can tell is in a cultivated area or very close to.  Probably only partially naturalised - at most.

There are no red-flowered Potentillas native to the UK.   Potentilla nepalensis is listed in 'Alien Plants of the British Isles' as a casual

garden escape i.e. not properly naturalised.  I doubt very much that the PURE, original Potentilla nepalensis has escaped.

There are quite a number of cultivars of P.nepalensis available but most have pink flowers.  A hybrid between P.atrosanguinea and P.nepalensis

is known.   Of these, 'Gibson's Scarlet' is one of the common ones.  I cannot see sufficient detail in the picture above to be certain but think it is

entirely possible that the plant you photographed is a cultivar with some P.atrosanguinea in its ancestry or other Potentillas not necessarily of Himalayan

origin.   Once in cultivation especially in places where they are being bred and deliberately crossed, can rapidly get mixed-up.  Does NOT appear pure

P.nepalensis to me.
