I’d like to dedicate this post to my blogging friend, Carol at Flower Hill Farm, for her long-suffering with this invasive plant, her nemesis, Bishop Weed, also known as Goutweed (Aegopodium podagraria).

But first, a disclaimer. I call this ongoing series “Most Hated Plants,” but some have taken issue with “hating” poor defenseless plants. Most Hated Plants is really a shorhand way of saying:

  • I don’t really hate the plants.
  • I do hate that nurseries continue to propagate and sell these plants
  • I hate that landscapers continue to install them
  • And I hate that people continue to plant them
  • Invasive plants are wiping out native habitats leaving wildlife no place to go
  • Invasive plants cost taxpayers $138 BILLION dollars every year
  • I really would like to see homeowners do their homework prior to purchasing ANY plant

But instead of saying all of that every time I refer to the damage caused by invasive plants, I simply say MOST HATED PLANTS as my short hand.

Bishop Weed is native to Europe, northern Asia, and Siberia and was brought to this country as an ornamental plant. It was first noticed to have escaped cultivation and become invasive in Rhode Island in 1863.

Also known as Goutweed, it wreaks havoc in moist, partly shaded woodlands and disturbed areas. It forms a dense mat that prohibits other plants from establishing.

This trait is especially harmful in natural wooded areas where it outcompetes native plants. Because of this, many native woodland plants are now highly endangered.

I’ve been attempting to rid my property of this plant since 2001 when I first moved in. It feels like a losing battle because it returns with a vengeance especially after the rain. We pull, and we pull, and then we pull some more. But it always comes back.

That’s because Bishop Weed not only spreads by seed, it also spreads by underground runners. If you’re pulling but don’t get every last piece of those runners out of the ground, it will pop up again almost immediately.

My neighbor across the street is the head propagator for Morris Arboretum. Her garden is her own beautiful private botanic garden. Really, it’s stunning! But she has been battling Goutweed for the 30 years she’s lived in her house. Trust me, she REALLY hates this plant!

Risa Edlestein, my blogging buddy at Garden and the Good Life, has started a discussion on the best ways to eliminate this invasive plant from the landscape at the Ecological Landscaping Association Group on LinkedIn.

It is banned for sale in Connecticut, Massachusetts, and Vermont, and is considered a noxious pest from Eastern Canad to Georgia and into the midwest, plus is invasive in the Pacific Northwest.

A much better alternative to this noxious, invasive plant is the native Golden Alexanders (Zizea aurea), in the same family as Bishop Weed, but a much gentler inhabitant of native ecosystems, and a host plant for Black Swallowtail butterfly caterpillars.

So, Carol, this one’s for you, in hopes that you will make headway in this battle!

New to this particular fight, not new to others!. I've been staying at a friends house who has beautiful gardens and a very healthy respect for native plants and omg so much bishops weed! I used to have 25/acres of vegetables and 5//of strawberries and this is a tough one. I've been clearing a half an acre for 2 months now!


contrary gardner

Jul 07, 2019 by Dale

Here's a contrary opinion as I have small areas of shade in my garden where nothing else will grow. Rather than blank dirt, I prefer Bishops Weed as I like how it lightens up shady areas. It doesn't spread that much and it's a distressed area no other plant likes. So, for that purpose I believe there is a place for this plant. It is not in a place where it can spread to a neighbor or a wooded area. At the very least, if one likes the looks of the plant, as I do, it can be kept in a pot.


Bishops Weed----we all agree! Here's what we did....

Jun 26, 2019 by Johanna

For the past 16 years I've been battling BW----and grudgingly admiring its tenacity! I con't even want to think how many days of my life I've spend pulling, digging. This IS an amazing plant and it had been growing for decades in a large patch in our yard.

Finally, I had had enough. Five years ago we cleared the ground and covered it with two layers of heavy black plastic. On top of that, a deep layer of brown mulch. On top of that, lovely pots of flowers and hostess, and a piece of sculpture. So there!

This autumn we will pull it all apart again, pull away the plastic, and restore the soil underneath, on the theory that not even Bishops Weed can survive five years without light and water.

What do you think, fellow gardeners? Will it, like the TERMINATOR, be back?


I hate bishop weed

May 30, 2019 by Dianna Simpson

I moved here 27 years ago and we had zero landscaping and little money so I began to transplant from friends and relatives. I planted a few bishop weed plants in their variegated form and thought they looked nice. Within a few years it reverted to its ugly green self and has invaded every space in my yard I pull it daily to keep it from wiping out the rest of my beautiful flowers. There is no getting rid of it... I have tried everything though the years.


Could survive a nuclear warhead

May 26, 2019 by Lisa

I fought this battle of hand-pulling for several years to no avail. I’ve joked that this plant would survive a direct hit from a nuclear bomb. What it (mostly) doesn’t survive is the Roundup for poison ivy.


Bishop Weed vs Artemisia

May 15, 2019 by Pat Bullen

I don't know which is worse - Bishop Weed or Artemisia. I fought a losing battle with both for 28 years before we moved to a house with both variegated and green artemisia -- no bishop weed thankfully. The battle continues ....


Golden Alexanders

Sep 03, 2018 by Kelly Ludwig

I have been fighting this invasive weed for 15 yrs , I brought it from my mom's house and today I saw all the black swallow tail caterpillars for the first time...I finally feel better about having this weed,stopped weeding my hill today.


all natural weed killer

Jun 28, 2018 by Michelle

I tried a pinterist concoction of 1/4 salt, squirt of dawn dish liquid, and whole bottle of white vinegar. granted it did kill everything....including the bishop week. Just noticed first time in yard this year. Neighbor shared that she has battled for decades...now I know where it came from.
but the mix does work to kill it, however, we do keep checking to see if it comes back...and so far, that's a no


I've given up...

Mar 17, 2018 by Ginger

I have spent so many nice days over the years trying to control this "evil weed" that I have decided to turn my side yard (used to be nice flower garden) back into grass. All the beautiful days that I should have been enjoying my flowers and planting new ones were spent pulling this weed. When I saw it for sale at Lowes last year I felt like screaming - instead I emailed them and complained about what an invasive plant it was. (Didn't make me feel any better but it does help to know there are others with the same nemesis)Thanks!


I made the mistake. ...

Dec 27, 2017 by Mims

Of planting variegated bishop weed in my zone 9 northern California yard 20 years ago. I pretty quickly realized my mistake and planted a miniature comfrey to surround the bishop weed, and hand pulled the variegated plant. It took about three years to wrench back control, and even now 20 years later I still see a sprout of bishop weed. Truly evil that plant. The comfrey is a spreading mat that is easily controlled, looks great, tolerates drought and shade.

Previous homeowners were thinking "wow! I planted that and look at it grow! I don't even have to do anything!"

I've replaced the overgrown beds of bishop's weed on my new property with native plants and non-invasives. Unfortunately my neighbors don't garden and so the weed tries to come under the fence again from their yard to mine.

How I did it on my own property though, was I uprooted all the bishop's weed right before winter, let nature freeze everything for a few months, and then in spring I uprooted anything that was left. I only see it pop up next to the fence where it's trying to invade from the neighbor's yard. You have to be diligent and go through each block of earth and sift through to find the nodes underground. They don't go that deep (a foot or less) so it just takes a little time.

Of course if you have a whole infested lawn it's going to take much longer... I would have the lawn dug up and re sodded.


How to rid?

May 01, 2017 by JR

I'm pretty sure this is what is all over my garden. I've spend days digging out the roots and I'm not even half way through my garden. Do you have any tips for organic methods to get rid of it? I agree, this stuff is awful! I also have Japanese Knotweed. Not sure what the previous owners of my property were thinking, but my summer looks to be backbreaking! Thanks!
