Eupatorium Joe Pye Weed

Friday, March 26, 2016

An off and on day that finally settled down in the afternoon and provided sunshine to suggest clearing sky and a nice weekend. This is a picture from last season of our hosta and shade garden. We think it's a very nice place to visit. It's still under construction after 6+ years but many of the hostas are mature at this point  and offer a first-hand look at where you will be in a few years if you start with a plant in a one gallon pot.

In 2011, we had three different floods on this property. Hostas can take a great deal of abuse including water as long as it finally subsides which it did. The real problem with the flooding was the introduction of millions of weed seeds. Some of these came from high in the watershed either up towards Walden or over towards Molly's Falls Pond, maybe even Peacham Pond and further towards the Groton State Forest. We were more fortunate than many farmers along the river that found themselves facing a bazillion new starts of Japanese Knotweed. Our problem has been eupatorium, also known as Joe Pye Weed. The native-to-Vermont eupatorium is a great magnet to pollinators just like the hybrids, but it is a more vigorous grower and it spreads quickly from its root systems and from seeds which are abundant. 

If you happen to live in proximity to a river where knotweed is common, keep vigil in your gardens for eupatorium too. In our image up top here, the eupatorium is the dark green plant, center picture, on the right side. Once it gets established to the size pictured, it is a bear to remove because the roots have taken hold and are already deep. It can be removed, it's just work! It's far easier to get going right away on the seedlings, but do beware that even their roots grow quickly and need persistence to remove.  If you are unfamiliar with eupatorium and want to see it first hand, ask me when you stop by and I'll show you the problem that it creates.
