Epimedium x youngianum 'Grape Fizz'
Description – E. x youngianum is a cross between E. grandiflorum and E. diphyllum, both species being native to Japan. This hybrid has occurred in the wild where the two species grow in close proximity, and in gardens and nurseries. The various varieties of this cross tend to be small to medium sized deciduous plants carrying medium sized flowers. These vary widely in colour and shape. Sometimes the shape tends towards E. grandiflorum or E. diphyllum, but others have quite different flowers unlike either parent.
We bought 'Grape Fizz’ this spring (2015) and therefore not had it long enough to fully appraise, but we have been impressed so far. In this variety the flower tends towards the E. grandiflorum parent.
