Alchemilla mollis; this Lady's-mantle species is an introduced ornamental plant which seems to be indigenous in south-eastern Europe. Like many wild Alchemilla vulgaris micro-species this is also a micro-species within the A. vulgaris group. On Iceland, it has been planted in private gardens and also in parks/meadows of (semi-)urban areas. It has a more yellowish-green appearance compared to other Icelandic Lady's mantles. Closer inspection reveales it has more hairs especially on the leaf-blades as well as other parts. Hence the name "mollis".
They are members of the Rose family (Rosaceae). The Icelandic name of this species is Garðamaríustakkur.
