This means that the canes arch over and the tips root when they come into contact with the soil.

R. armeniacus reproduces both vegetatively and by the production of seed. When undertaking physical or chemical control methods of R. armeniacus, it is imperative to plant desirable native plant species on the site to help reduce re-invasion by R. armeniacus (Stannard, 2014). http://www.hear.org/pier/index.html.
