    About 8 years ago a friend gave me a single New York Ironweed plant. Today I probably have 50 and would probably have more if I didn’t kill off some of them. It is easily 6 feet tall, and the bees sure do love it. It is a tad more aggressive than I would like and spreads fairly long distances pretty easily. I have heavy clay and it doesn’t seem to notice. Also it goes through droughts just fine and I never water it.
