The Wall Street Journal has a fun piece today about invasive bamboo and a slide show that includes other invasives, too. (Sorry, the link won’t work if you’re not a subscriber.)
I have personal experience with two of the invasives in the slide show:
Garlic mustard, which blooms so fiendishly early that I’m always busy in the vegetable garden when it needs to be yanked. It also continues blooming, as the Journal mentions, even after you pull it out of the ground, and it blooms when it’s just a few inches high, so it’s absurdly prolific. At least it’s yankable, unlike
Purple loosestrife, which laughs at Round-Up and being cut back before flowering and whose roots are so strong that I’m unable to remove them even with a pick-ax and lots of martial-arts-like shouting and grunting. I’m completely stumped by the loosestrife around my pond and have reconciled myself to a color scheme that takes it into account.
