Epimediums

Epimedium grandiflorum 'Nanum'

‘Nanum’ is a delightful smaller form of E. grandiflorum. In good light the new leaves have a conspicuous brown edge. This doesn’t show as prominently or not at all in shadier situations. Please see the two pictures below. It is not all that small when well established, as we have found with our show plant in an 8 inch diameter pot where it must be close to a foot high by the end of the season.

General information on Epimedium grandiflorum

Distribution – Japan (Kyushu, Shikoku, Honshu and Hokiado). Northern Korea and southern Manchuria.

Description – A medium sized fairly deciduous species with widespread distribution through Japan etc. growing in deciduous woodland. It was introduced to Great Britain in the 1830s. With its wide geographical range through the various Japanese islands etc., a good deal of variation has occurred. Flower colour of the plants found in the wild varies widely: yellow, white, pink, lilac and reddish to purple. Add to this the large number of plants attributed to E grandiflorum that have arisen in cultivation and there may be hundreds of cultivars already named.
