Having just left Sainsburys in the centre of Norwich, I noticed a small white 5-petalled flower poking up at the bottom of a wall, along the edge of the pavement. There are many plants with 5-petalled white flowers coming into flower at the moment, but this one stood out as being different. The leaves were lobed and unmistakably the leaves of Rue-leaved saxifrage Saxifraga tridacylites – notably in three lobes as indicated by the Latin name. My first encounter with this species was when I identified it in my garden, since then I have come across it on some of the specialist calcareous botanical sites in Norfolk. My impression was of a rather dainty plant with a strong red colouration, however, I was initially fooled by this rather bold looking bright green plant looking very happy in an urban environment. However, on closer inspection, the red colouration was evident, together with the characteristic, abundant glandular hairs.
