Hops are healthy and fast growing twiners that can quickly cover large areas without causing structural damage. Hops are a good choice for inexpensive high greening, for down pipes, and balconies. For facades, however, there are better climbing plants (grapeless grapevines, for example); Hops are perennial and will last only one year (so there is no lignification), the new shoots growing out of the ground every year. They will die in autumn and then need to be removed from facades (fire protection), at least every 2 - 3 years. FassadenGrün offers pure female plants (beer hops) and the variety "Aureus" (golden hops).
Beer Hops - Humulus lupulus
This is an extremely fast-growing twiner which does not lignify and dies back to the ground in autumn. New shoots appear again in very early spring, and the young asparagus-like shoots are edible. In warm temperatures grows up to 1 metre per week; grows up to 10 m height. Leaf shape similar to grapevine, foliage from April to October. Another less vigorously growing species is the Japanese Hops Humulus scandens, an annual plant which propagates itself by seed. Hops is dioeceous, with female plants mainly being cultivated for beer hops production. The male flowers are inconspicuous panicles, the female ones catkins, and the famous fruit is light green. If necessary, thin out the young shoots in very early spring; in autumn remove remaining leaves and shoots with a rake.
Lightning conductors, downpipes, balconies, balustrades and railings, masts / poles, struts, and other already existing climbing supports can be used, whereby twiners that form strangling stems are not to be planted around such structures. Obviously hops grows well on all other climbing support systems as well... For suitable wire rope systems, see below. Best are simple wire rope trellis kits in the basic, basic-s, or medium range.
