Well, I think I’ve found at least one plant that I won’t be planting on my layout again: wirevine.
This stuff is amazingly tenacious and ridiculously invasive. I planted a single 3″ pot of it last fall, and it’s gone crazy. Not only did it cover the cleared area where I planted it, it jumped (over and under) a paver, climbed two dwarf Alberta spruce, became intertwined with two other ground covers, and keeps trying to cross the right of way despite regular applications of Roundup. And places where I’ve pulled it up, apparently roots and all, it’s come back. All in about 8 months.
But if there’s someone else out there who needs to model Kudzu, this is your stuff.
