I had this planted in my garden in Arizona and currently now in Georgia. It was quite beautiful in Arizona and did very well. The plant did not spread as aggressively as it does in my Georgia soil. I am assuming the alkaline soil of Arizona kept the plant tamed, but here in Georgia's clay soil it is very aggressive and will intermingle its roots with nearby plants. I am constantly pulling up rooted plants that have spread five to six feet and is a pain to weed it out of other flowering plants.Once I think I have pulled up all the roots it will pop up somewhere else even in the bordering lawn. This plant has rooted itself so well through out the flowerbed the only option I have is to completely dig up and rid every plant in the flowerbed to include the contaminated soil and start from scratch. Beware! If you have clay soil I would recommend only potting this plant unless you do not mind a large flowerbed of only variegated mugwort.

Result after 4 years: Incredibly invasive and difficult to remove from the landscape. Beautiful as a potted plant. Don't plant this unless you have somewhere near no other vegetation and can allow this plant to do whatever it wants (because it will). Here's why: This plant was incredibly invasive and difficult to remove. In fact, I haven't completely removed it. I bought it as a little 4 inch grower plant from a nursery about 4 years ago. I had transplanted it once. It was about 30 inches wide and grew to about 3-4 feet tall. It is beautiful. Problem is that it started growing into the other plants around it (around this plant means within 5 feet of it). I pulled it and put a few sprigs in a pot. Gorgeous in a pot - keep it out of your garden unless you want this plant to be the only plant in your garden.

While I haven't had any problem containing this plant in my OKC clay soil that is slow to warm in the spring, a friend I gave some to has it in sandy, moist soil and morning sun.
Her plant has spread at least eight feet in all directions and is now invading her lawn.
Too much of a good thing, I'm thinking.

Don't let this plants beauty fool you, it is extremely invasive! I planted this four years ago in the wrong spot. I was a novice gardener and it overgrew the area. Moved it across the yard and noticed some "residual" pieces coming up later. I was attempting a bit of an english garden affect next to my house last year and moved the leftover pieces there.
Long story short, it is coming up everywhere this year. I started attempting to dig it up in the past couple weeks... 10 hours and 3 large buckets of roots later, I still have a 4 ft. section and then some to dig up. It so took over that I had to give up several favorite plants because it grew and became so intermingled that I couldn't separate it. STOP YOURSELF NOW... find something less invasive. You'll thank me in the long run!

There was a bed made of rail road ties next to my house, along side the deck, rocky and full of clay. Nothing was growing there but chickweed, and I didn't have time to mess with it. Someone gave me one of these plants, along with a lamb's ear, and said they would grow anywhere. Sure enough, it's doing great. It did grow into quite a large bush, nice mottled yellow-green foliage. It's lovely and it's not chickweed. Also, I really just ignored it, but it looks well-loved. Really amazing.
I just went back in to edit my rating on this guy. Still beautiful, but, as other comments have indicated, it's really pretty invasive. I still like it and don't regret planting it where I did, after all, nothing was growing there but creeping charlie, but I was thinking of planting it around the yard, and now, no way! Four years have passed, and it is only just now getting out of hand, so that's not bad.

I have now had this plant for over 2 years. It is planted in full sun in rather good soil and in with many other herbs. I have had no problems with it being a thug or spreading uncontrolably. It is however over 6 feet tall this year and I am loving it! The foliage is gorgeous and I enjoy it immensely. I really tend to ignore this plant as far as much attention or fertilization. Maybe that is why it isn't spreading like others have described. I don't know, but I say it is well worth having in the garden!

This is one of my very favorite plants. I love plants that go their own way and do their own thing. I don't have a problem with it wandering since I give it plenty of room to start with. I have it planted around my tree in the back along with mugwort and the combination is (to me) breathtaking. The yellow/lime green leaves peeking out among the silver mounds of mugwort. Beautiful. I've had it for a few years now and when it seems to want to wander off in a different direction, I just uproot it and put it where it should be. I have no problem with that. The colors more than make up for the wandering. I don't find it invasive at all.

This plant struggled for 3 years, then finally caught on. Having seen its aggressiveness at my sister's place (much more alkaline soil), I moved it out to our pasture border where it can colonize at will. I'm staying neutral on it so far, although it does have beautiful foliage.
I have kept this in a large pot (on concrete) for about 10yrs. I love it, but would never plant it in the ground! It even creeps out the water holes on the bottom of the pot. So if you ever get it, do your self a favor and keep it off the ground ~ that way you can enjoy all it's attributes!

In New Jersey, Zone 6b....I planted artemisia as part of a container planting in full sun. It did not take over...as a matter of fact it remained smaller and more "in place" than I hoped it would. My intention was to add foliage color to the nemesia, calibrachoa, osteospermum, twinspur and juncus that was there but it just didn't do much. Might have been the differences in water requirements for each of the plants I chose though.

While the silvery artemisias struggle with the heat in my area, this plant is extremely invasive! After two years I still can't get rid of it. I gave my sister some the first year I had it and now she's constantly complaining about it! My other sister begged for some this year but I made her promise to only grow it in pots. I told her I don't think she'll be happy with it. It grows very fast and covers everything in the flowerbed or pot if I don't pull it out.
It moves by runners underground and I can only seem to get rid of it by pulling out the roots. Unfortunately, it grows faster than I can remove it. It's growing in full sun but it seems to grow just as fast in a pot I have in afternoon shade. I hate chemicals but out of desperation I tried Roundup which didn't work either. BEWARE!

We just moved into a new house and this plant is consuming, what I think, was once a nice little planting near the end of the driveway. I am already starting the process of removing it and fear it may never be eradicated. It is towering over the other plants and is consuming them entirely. Yuck!

Yes I guess you could call it invasive, but it's easy to pull up. It does grow fast so I often cut it back. The color is just too wonderful to pass up. I have it in a bed against a weathered fence, it always looks great. I have heard it does best w/ part shade, in my area; however, I have it in full afternoon sun and possibly that has made this plant less invasive for me. I love it.

NEGATIVE!! NEGATIVE!! NEGATIVE!!

NEGATIVE is a mild word for how I really feel about this!! The normal bermuda grass and nutgrass are mild invaders in contrast to this assailant!!!

I loved the chartreuse color and adaptability to my zone. I planted it in the fall and by early spring it was everywhere in my bed poping up over 20 ft away from the origional location in less than 4 winter months. I got it out and never will plant it except in a garden I want to dissapear.

I bought one last year because it is a very attractive plant. But this spring it came back with a vengence and it's everywhere. I dug out the original plant, I've been digging plants and runners all year, and it still perserveres.
I bought a home whose yard consisted of nothing but mulch, mulch, mulch - up to six inches deep in some parts. I was so taken by this plant's beautiful foliage and graceful appearance that I planted it early last spring. It is now coming back up. It has spread, thankfully, beyond the three original plants. I like the fact that it will grow tall and spread out - just the thing for my miles and miles of mulch. I look forward to seeing it grow.

This "may be" invasive plant is a real thug! I planted this in a somewhat "unhospitable" place, thinking it would reduce it's "thugness". Boy, was I wrong!!!!!! If you don't want dozens of babies flung far & wide (10 feet or better from the parent) don't even bother with this specimen! It really is a shame, since the foliage is extremely attractive!

Planted it last spring and was about 2 feet tall by winter. Stayed in a nice compact shape. Was told by the GH owner that most grow it here as an annual but I am hoping it comes back. Did not find it to be invasive at all here.
May 2004 - Adding that I have plants growing more than 2 ft. away from the original, zone 4. A very hardy plant, quite striking. After digging up some, I discovered that all were spread by runners from the original, none appeared to be from seed. They look beautiful under the Oriental Lilies but will be removed if they spread farther than that. Definitely can be considered invasive.

If you think you'd like to ADD this to your Garden, better be prepared for it to take over.. I bought (1) Plant in 2001 and split it in 2....and just one year later and it's all over the Flowerbed and I've seen it in my Grass too while Mowing, so I guess it's safe to assume it spreads by seeds which are blown by the wind..You'd better really like this before you plant it.....it's also VERY TALL.....much taller then the information stated. I've had to cut it down 3 times so far so I could "SEE" my other plants....and it caught back up in NO TIME.....But all in all, it's a KEEPER!
