Get your ladder out every two weeks and trim the tops to stop them from getting under your shingles. Commercial height is 18' generally. Mine are 15', and the top stringer line will be covered almost as much as the trellis lines by the end of the summer.
Willamette on the left. After some rhizomes failed on the right, they were out of Willamette and I've completely forgotten what the replacements are.
Seems that area of ground on the right JUST WON'T GROW. Extreme right however, is a climbing rose bush that has survived every attempt to get rid of it.
