I can't locate my past post on garden cancers. I am not talking about evil weeds like Porcelainberry. I am talking about things we plant on purpose which have the power to take over and destroy a planting area.
Such things should only be planted where they can be mowed around because they spread underground, or just spread, to the point of overwhelming everything in their vicinity:
Wisteria
Bamboo
Trumpet Vine
Members of the Mint family (best let to go wild in a meadow)
English Ivy
Pachysandra
I had a few more on my list, but I can't remember right now.
