Epimedium grandiflorum 'Bicolor Giant'

‘Bicolor Giant' is a new variety of E. grandiflorum to us, and we therefore are unable to fully appraise it, as yet. So far it seems to be a fairly vigorous plant and the flowers are large, but tend to be under the foliage and not produced in quantity. This may improve when the plants are mature. This is a medium to tall variety of the species.

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.
