The hop plants you see are grown at a friends house. This particular couple loves to grow hops strictly for decoration. They don't brew!
In fact, they used to just let the cones turn brown, cut down the bines and throw everything out in fall!
So naturally I offered to put them to a much better use! In turn, I help them cut back the bines and I keep them in homebrew all year. Pretty good deal for me!
The cascade are several rhizomes (3) that grow up strings to a pergola where it then creates a shade canopy for the patio. (Very cool to sit and drink beer on a summer day under the canopy of hops!)
The hallertau grows on a standard trellis until it reaches the top and he then runs several strings to the peak on the house.
