When I first purchased my house in 1988 I thought how lovely this plant was in the terraced flower gardens - Three years later it was getting out of hand and four years after that I embarked on an eradication program. About the only thing it did not crowd out was poison ivy and wild daylilies .

Last year after 20 years of pulling it every summer I thought it was finally gone for good. Wellllllllll..........

It's baaaaack - so this year I am doing a new approach - When I pull it -- any snapped off root I see I hit with my buckthorn blaster - hopefully that will kill the roots

I have this plant in a semi-wild garden where it mixes with pulmonaria, bee balm, wild ginger, bleeding hearts and sweet woodruff. I let them fight it out amongst themselves and the pulmonaria is winning. Some years I don't even see the gooseneck loosestrife bloom because the deer eat it if I don't stay on top of a spraying regimen. I am surprised to hear that it is so invasive for many. Not too many plants are able to cope with our clay and shale, perhaps that and the marauding deer keep it in check.

I've had this plant in various gardens in Wisconsin, and now I'm in Kentucky, and have a few growing on a hillside. I know what I'm in for, but the alternative is poison ivy and the **** Japanese Honeysuckle that's running rampant over much of my vertical acreage. I'm willing to take the risk with the gooseneck loosestrife, simply because I'm not allergic to it, it's prettier than the honeysuckle, and I'd rather keep an eye on this than the other two.

This species has naturalized in 15 states, but is not listed as ecologically invasive in any state.

In the garden, this is an aggressive thug. The shallow pink rhizomes spread very rapidly under ideal growing conditions, up to 4' in a single season. In soft moist soil they are easily pulled up unless they've penetrated the root ball of another perennial. In heavy soil, good luck!

Bihoreau's description above sounds like Veronicastrum virginicum, not gooseneck loosestrife.

And YES that is invasive. Just a good thing if you want minimal soil prep for a lawn or yard rehab.
I am wondering if it is safe to plant at the base of maple trees? Or burning bush trees. Sometimes plants emit noxious substances and harm other plantings that way. Anyone out there have any info if this one would do that?

Loosestrife multiplies by runners under the soil, and can become invasive. If you don't want gooseneck's taking over your garden, you can plant them in a large pot and sink it into the ground, or plant in a large raise bed. If it becomes necessary to control plants spread, you can dig out excessive growth from the edges of the clump. If not kept in bounds it will soon take over and appear everywhere in the garden.

I moved to my current home two years ago. I found a thick circle of Gooseneck growing in my front yard (most of my yard is mature sub-Appalachian forest). The circle is 12-15 ft in diameter, and has 100's of blooms each May-June. The flower stalks are uniquely attractive. It took 2 years to find out what this plant was, until then I called it duckhead, because the bend flower stalks, when in full bloom, look like the profile of a duck's head to me. Gooseneck makes sense too. They have popped up elsewhere, but if I mow them when about 6 inches tall, they are gone for a couple of years. I love it. No maintainence at all, except some watering during southern summer droughts.

This is a case that illustrates my favorite Latin saying: de gustibus non disputandum est - which means "you can't argue about taste." I like it, though I definitely agree about its aggressive qualities! My daughter gave me a few plants several years ago, and I transplanted some to other garden plots. It is going strong in its original setting, and also in several where I transplanted it. It has not crowded out the lilies, tulips, daisies and other flowers in its original site, but it is definitely a strong contender! I guess it's like those who love, and those who hate, mimosas, one of my favorite trees!

Just to even up the score a bit, I must say that had I read the comments about this plant before I accepted it as a gift from my sister's garden sometime before 2001, I would have tossed it in the compost. As it is, it has been rather neglected in the dry, shady corner of my yard under Rose of Sharon bushes, and edged by grass. It has spread but without being invasive. It droops during very dry weather, but maybe this keeps it more in check. It blooms the same time as the bushes so it is quite striking. I am looking at it with a different eye, however, and will be more vigilant in keeping it confined.

The woman who called it a botanical bully said it best, but let me add my two cents.This plant is extremely invasive and difficult to remove. I had it planted in a dry, sunny spot in rich soil but never watered it. This is in Eastern Massachusetts. Years one and two the plant looked good, but this year it spread so much that I yanked up all of it, or at least I tried to. There are so many beautiful well-behaved plants, and many others that spread, but can be pulled up easily. This one just isn't worth the hassle.

I tried to contain this by surrounding it with aluminum flashing. (Burying that was QUITE a task as it went down a good 5 or 6 inches!) The loosestrife went over the flashing, under the flashing, THROUGH the flashing! Once I realized that this thing would not be contained, it took me a summer of digging and chemicals but I got rid of it. So be warned! This is Chicago, zone 5, NOT an overly wet site.

I put them in a large plastic decorative planter (with only 2 small drainage holes). The planter sits in the shade and they do quite well there. Every fall I sink the planter and pull it out in the spring. They have come back every year, stay contained in the planter and brighten an otherwise dark corner of my garden.

First and even second growing seasons this plant was a delight.

Do not plant it, and avoid nurseries that sell it!

It is stunning when in bloom and has nice green foliage when it is not. I have it planted in full sun in a bed that gets VERY little attention and almost no watering except during times of prolonged drought. It has never tried to reseed outside the bed, but the single plant I started with five years ago has turned into a nice large clump. This spring I am going to divide it and move some to other places so I can enjoy it even more.

Maybe this plant is "invasive" if it is grown in a constantly damp area (as is purple loosestrife), but grown where it is kept fairly dry it is a very well behaved plant and one of my favorites.

It makes nice cut flowers to add to a mixed bouquet.

I really enjoy this plant. Passerbys always stop to look at it (especially when it sports one "head" and two "beaks" - lol) and comment. However in full sun and continuously moist or clays soil (next to your fishpond or near your cabin's lake shore) it will certainly become an unruly guest. I recommend planting gooseneck in partial sun, or on the north side of the house. As long as it is not allowed to dry out, it will do well and not become invasive, though you may want to divide it every fall and give some away to those passerbys or gardening friends. :)

While some may have problems with this plant, I've found that it's been choked out by other far more aggressive plants. My mother planted this years ago and we're down to one large clump in "The Darwin Garden" aka her perennial bed that went neglected for several years, which I am now trying to restore. Instead of trailing all over the place, it seems to settle in nice, neat clumps. It's great for cutting and adding as gorgeous filler in cut flower arrangements. As others mentioned, it's easy to pull if it ends up where you don't want it since it has a limited and short root system. I haven't seen it show up out of nowhere like myrtle and other plants do, but whatever you plant will double consistently.

But it has proved very difficult to contain. Those runners--which feel suspiciously like red rubber cables--go everywhere. It has not been fun digging them out from a nearby shrub rose every year.

When we moved into our new home 4 years ago, we were thoroughly pleased with the beautiful garden we inherited from the prior owner. As I began my journey into the gardening ranks, I appreciated the gooseneck loosestrife for the life added during hot summer months. Four years later, I've grown out of favor with this monster. When a couple of noteworthy perennials stopped returning 2 years ago, I didn't know what to think. Now that I see these reddish white (magenta-like) roots protruding through the flower bed and destroying my "new" lawn, I suspect the loosestrife is to blame. I guess it liked the wet area created when we reseeded our lawn and decided to join the party.

I cannot really say if Gooseneck Loosestrife (unrelated to purple loosestrife-different family altogether.

I use plants like this in those areas where nothing grows and it spends large hunks of time a mudhole. It is planted with marshmallow, and Joe Pye Weed, Yarrow and now Ligularia seeds. There is a space lawn mower sized between the plants and the shrubby wetland, and it is mowed several times a year.

From what I hear here and in my garden club, it can be good for specific circumstance but only if you have the time and expertise to keep an eye on it.

I love gooseneck. Yes it can be invasive but you have to plant it where you want a strong grower. I mix it with nicotina, cosmos, delpheniums and they simply spill out beautiful gooseneck flowers and fill in all the gaps that weeds would normally try to fill in. They are perfect flowers for cut flower arrangements. Not a good plant for someone who wants to not be an active gardener. It will spread rapidly if you do not maintain your yard.

This plant was in an almost sunless north-side flowerbed when we bought our old house in MD 2 years ago. I have never seen any plant do so well in such an uninviting environment. The house is on a lovely ridge but the location is hard on plants due to the heavy clay and stony soil, little water retention, and full exposure to cold north winds in the winter. This plant has thrived on the adverse conditions and we still have to work to keep it contained in its bed. Still, it's nice to have anything flower in the spot that it's in. I'm sure the previous owner planted it there simply because the loosestrife was one of the few plants that could survive in that spot.
Mind you the south side of our house is a whole different micro-climate. It's amazing.

(I garden in the Mid-Atlantic). Pretty, graceful white flowers. Children love them as they look like gooseheads. Grows in sun to part shade in a variety of soils. Very easy. As stated, can be very invasive. Spreads by the roots. Plant in a pot or a confined area. Not a plant for the perennial garden, (will choke out other plants, even chokes out mint!). However, planted where you want it to spread, or where you need to take up space or cover a bare patch, and quickly, or where nothing else grows, it's perfect. Mine spreads beneath a lilac bush with violets where nothing else grows. Will choke out weeds. Bees love them. Pretty for cutting. Clip after flowering to prevent seed set, (although primary means of spreading is by the roots).
