Which invasive plant is the most troublesome in your garden?
My villain is creeping buttercup - ranunculus repens. Not yet listed as an invasive plant in Washington, but is on the "weed of concern" list. Originally from Europe and is quite troublesome for me, although I do attempt to coexist with it -- I've had many non-gardeners complement me on the pretty yellow flower mixed here there and everywhere in my beds! And of course I do have fond childhood memories of holding the flower beneath our chins to see who likes butter.
Glechoma hederacea, Creeping Charlie. Hate it. Hate it. Hate it.
I can handle whatever pops up in the garden. It's everywhere else that's a got a real problem-Japanese knotweed, Burning bush, Bittersweet & Multiflora Rose. And Barberry. And Phragmities (sp?).

Japanese Honeysuckle...noxious weed here, and our woods are choked with it.
Bush honeysuckle and chickweed. The honeysuckle isn't a problem in my yard, though I have it, but in the woods around here. Also japanesse bindweed.
That purple stuff that is in bloom. Both varieties. Wild onion, bermuda, ground ivy, honeysuckle, mimosa, morning glories, Johnson grass, and whatever else I do not want in my yard. I have tried to find out the name of the purple stuff but will have to keep searching. Luciee
I found it on Dave's weeds. It is red deadnettle, Lamium Purpurum, and henbit, Lamium amplexicaula. Thanks! Luciee
I voted other.
I constantly battle Creeping Charlie. It "creeps over from two adjoining neighbors yards, even though I spray several feet of their property (with their permission) with weed and feed .
Milkweed vine is another pest. I keep all the starts pulled up in my yard but several of the neighbors let them grow wild.
Creeping Charlie, Glechoma hederacea. Beautiful little lavender dragon flowers but invasive and annoying.
The Hottuynia Cordata is really pretty but I don't want any of that, either! :)
Hey- maybe we could swap and put them together in a hanging basket...!
I've sent it to two people who really wanted it - one in Las Vegas and one in Arkansas. It died for both of them. How I wish it would just die for me. My helper and I sprayed it many times last fall so I'm hoping we finally killed it.
My least favorite invaders are bur buttercup and alfalfa. The people we bought our house from had nothing but dirt and weeds in the backyard and we're still digging out alfalfa roots.
My invasive is plain old sod grass. I can't seem to stay on top of it. I have borders on my beds but it just goes under them. I should have made them deeper.
Chinese tallow trees. They're everywhere and reseed like mad.
Privet. Can't kill it.
Chamberbitter. Horrible weed.
The bermuda grass really likes my garden. It creeps under the fence and a 2 ft brick path from my neighbor's backyard. I'm finally getting a handle on it though the "war" has been going on for 20 years. It will probably find & cover me when I'm dead & buried. LOL
Hey pirl, I have seen cordata for sale. Thanks for posting it. I know not to buy it, even though it is pretty. Since this is invasive plant week, I will add some more weeds: white clover, monkey grass ,(just try to get rid of it) mondo grass, (been digging that up too) wild strawberry, nut sedge, canadian thistle, etc. I know all these are not invasive, but I'm just listing weeds. Luciee
I'm with the Bermudagrass group. It grows anywhere...in my flowerbeds, in my containers, under landscape fabric...under my paved driveway. In the event of a nuclear disaster, it would survive along with the roaches.
I voted honeysuckle, since it has almost killed a few shrubs here. But my most invasive in the garden is Virginia Buttonweed. It started out in a small area and now its everywhere. Looks like a pretty ground cover with its shiny leaves and white flowers, low to the ground. It propagates via stem or root cuttings, stolons, and sets a huge amount of seeds. It got into my raised beds and I dismantled them last year. I want to use the chickens to kill it this year, they love it. Just have to get the fencing to be escape proof and let them loose...
Melody - I know the feeling. When we have something invasive that eats up our time in the garden we just want it gone now.
Glechoma hederacea, Creeping Charlie; nut sedge (Last summer I bought a great big truckload of 'topsoil' and it was FILLED with nut sedge!!!) I'm just waiting for it to come up; I heard about some stuff called Sedgehammer, and I'm gonna try it.
I've heard of Sedgehammer on a radio gardening talk show. Hope it works for you.
And plenty of bittercress too, and a whole lot of other stuff.
Much as I like to feast on the himalayan blackberries (fresh, pies, jam), they are quickly overtaking large portions of our wild areas. Difficult to eradicate, although goats will eat them to the ground.
Dealing with crabgrass too. Don't even have regular grass in yard really. Just nasty, horrible crabgrass.
Believe it or not - MONARDA! It is beautiful when it is blooming, but before it looks like a weed and after it gets mildew. I have been trying to eradicate it, but it just will not go away. Trying roundup this year.
Only polite name I have is "Quack grass" Roots can go 2 or more feet underground and come up right in the middle of a daylily. Salt will kill every thing else in the asparagus bed, but not this.
Congon grass don't think I am spelling or saying it right
crabgrass and chickweed!!! Hate the wild onions! They are all over too and worst to get out. Johnson grass is hard to get out too.
Not sure what this weed is but I didn't have a problem with it until last year. It came to me with heavy rains washed down from other's yards. Again this year it is abundant like a massive ground cover. The picture is on a 2 x 4 deck railing to give prospective. It is easily pulled up but so much of it is daunting.
Other than that I guess the privets deposited by the birds are next.
It looks like some form of Lamium. Deadnettle and hen bit have pink-purple flowers. I do not know of a blue flowered lamium, we do not seem to have it here. Luciee
Bermudagrass (Cynodon dactylon).
A few others, including Bittercress, can be bad, but this is far more difficult for me to control.
