Epimedium x versicolor 'Sulphureum'
Description – This is the commonest and most widely available variety from a cross between E. grandiflorum and E. pinnatum subs. colchicum. It is a strong growing and reliable plant which has lived for many years in our garden, with little care or attention.. The individual flowers remind me of miniature daffodils, with a tiny perianth of white inner sepals and a corolla of yellow petals. It forms a middle to large sized evergreen plant slowly spreading, creating a dense mat of rhizomes through which few weeds can penetrate or compete. You can cut the old leaves off in early spring, but it isn’t too important, as the flowers are held clear of the leaves.
