Overall: I have found Acanthus to be the most difficult plant to get rid of. I had it planted near the front of a mixed border of shrubs and paeonies where it looked lovely - for two seasons then I found it coming up all through the other plants over a radius of four or five feet. Because of the nature of the other plants it was not possible to dig it out easily and I have been trying to get rid of it ever since, by digging it out to a great depth,using glyphosate etc and it is still coming up. Plant with care is my advice.
