The plant, in my experience, holds on tenaciously both at the root level and the climbing bine level . . . one can go on pulling and digging at the roots and shoots and they keep going, regrowing even from the smallest bit left behind and out of the compost heap as well. Once planted it is tenacious and near impossible to push back, contain, or get rid of. Reflective of the personality who just won’t let go . . .
