A previous owner left me with a garden full of Houttuynia cordata (also called hearleaf/lizard tail/chameleon plant), an invasive weed that I've been trying to eradicate. I can't believe it is sold in garden stores; it's far too aggressive. It sends these little whitish lateral shoots about 12 inches deep in all directions and thereby spreads under fences and into all the other flowers in the bed.
How can I get rid of it completely?
