'Variegata'
Less vigorous which may be a good thing for many gardeners.
Its deep green foliage is heavily and boldly splashed in white. It looks great on fence or trellis where it has climbing support.

Humulus lupulus ( European Hop )
A very fast growing ( often invasive ) and spreading, herbaceous perennial vine, reaching up to 30 ( rarely over 20 ) feet in height. It is native to moist woods in most of Europe to central Asia. The subspecies var. cordifolius is native to Japan. The stems die back to the thick rootstock during winter.
The foliage resembles that of Grapes. The leaves, up to 6 x 4.5 inches in size, are deep green above, bright green beneath.
The male and female flowers occur on separate plants during early autumn. The female plants only produce hops.
Hardy zones 3 + in full sun to partial shade on deep, fertile soil. It thrives well in harsh climates including south-central and southeastern Alaska as well as southern Manitoba and Saskatchewan. Cut to ground after autumn frosts. Propagation is from root division after fall frost or early spring.
