    A MASSIVE weed. This thing grows and grows and grows and grows. Can get to be over 4' tall and 6' around. Self-seeds, sends out runners. A borderline nuisance plant! However, VERY bee friendly, so if you want to attract bees to your yard, get these. Just don't plant them around a walkway. Tolerant of poor soil, tolerant of extreme sun, tolerant of flooding situations (3 weeks of rain last year). Very long taproot, but not deep. Sends the root off to the side rather than down. Flowers last for weeks, but not vase-friendly.
