If ever a plant could be described as elfin, it must surely be Epimedium diphyllum from Japan. Semi-evergreen, but unfortunately the old foliage looks like an attack of moths in an old persons wardrobe.
In spring the gorgeous white flowers are produced among the copper tinted new leaves with their distinctive
paired leaflets. It is a tiny little blob of tufty freshness in spring, more delightful than opening a box
of chocolates and finding that your favourites haven't been eaten yet. It doesn't really spread, just
digs its heels in and stays put. Heaves a deep sigh and expires in the presence of thuggish neighbours.
