Bamboo only with a very good root barrier
The Fargus does not need a root barrier
or must then be cut back over the winter (Clematis).
There are types of Clematis that do not need to be cut back. They regrow from the long "branches". I also have one... a blue-flowering one in the west, but I don't know what it is called.
What kind of "design elements" do you have in the garden?
A greenhouse, a reinforcement mesh as a climbing aid, a rusty heart on a stem in the shrubbery, also a birdbath for the birds there, several large stones with faces (sculptures). Nothing colorful. Currently, small stones are hanging on the fruit trees to prevent the branches from growing upwards.
