Androsace sempervivoides

Rock Jasmine. A Himalayan species yet  easier than you would expect, with leathery leaves, stolons make tight beautiful mats in winter, then transform in summer with inflorescences  on tallish stalks, spreads by stolons which are another interesting feature, sprouting out the top of the rosette in growth. As the flowers age the central boss changes colour. H 5cm including flowers. Hardy, sun.
