I keep wanting to get rid of this plant, but when I see its blooms, I rather like it. It is invasive, but again I have no idea what it is. It reminds me of something rather sinister, like death. I like lilies, but again I equate them with funerals. So many brides have them as wedding bouquets. It's the same with yellow chrysanthemums - in France you have them at a funeral.
