Is Rubus calycinoides invasive?
I have a volunteer plant of Rubus calycinoides that has appeared on the edges of one of my flower beds. Because it is a plant that has long interested me, I am considering using it to replace a groundcover I planted years ago, Muehlenbeckia nana, which is beautiful, but has proved to have a much too invasive root structure. I know I can prune the long stems of rubus, but will the roots become difficult to remove if it ventures beyond the areas where I want it? Thank you for your help!

Thank you for your question. WSU does not classify it as invasive: http://www.pnwplants.wsu.edu/PlantDisplay.aspx?PlantID=351 Good luck!
