    This plant is common growing along roadsides in my area of Tennessee. I found loads of it growing on county land alongside our local dump. I checked at the dump station to see if they would mind me digging up some in March, and they said no problem. They consider it a weed and mow it down in early summer. You do need to select your digging spot in summer when you can see where they are located, but then in early spring just look for the tall hollow dried stems. I didn’t even get a complete set of roots on each plant, and all the ones that I dug did great. They produced healthy, beautiful blooming plants that drew lots of butterflies. For me they are especially nice because I really need something that can compete with the Monarda that is crowding out many of my other plant species and this can. I am already planning to dig up more this coming spring.

    I find it hard to tell the different Joe Pye Weeds apart–this one above versus E. maculatum (Spotted) versus E. purpureum (Sweet), and I wasn’t sure which one I had actually dug up. Here are some handy ways to tell them apart:

    (1) Joe-Pye-Weed (E. fistulosum). Stem is tinged with purple but seldom spotted; stem has a white bloom that rubs of easily; cross-section of stem is hollow or has a hollow tube in the center. Also called Hollow Joe-Pye-Weed for a reason :).
    (2) Spotted Joe Pye Weed ( E. maculatum). Stem is deep purple or purple spotted.
    (3) Sweet Joe Pye Weed (E. purpureum). Stem is green and often has a slight slight whitish bloom that rubs off easily.

    P.S. I have my plants in regular garden soil, not a damp depression, and they are doing fine. Plant may be more adaptable than the books describe.
