Google it for a picture - I've checked in the alphabet section below, but its not listed there, though I'm sure someone will be growing it and probably also has pics of it on the site, just don't know where.

It is a rather coarse upright deciduous shrub. Mostly grown for foliage (yellow or purple). Fast growing to about 1.5 to 2m, then slows but can still reach 3m. Flowers are not much on the golden leaved ones, work ok on the purple one (in my opinion). Leaves like Viburnum opulus. It is good for the back of a border.
