After constuction caused terrible errosion behind our house, we couldn't get anything to grow in the shady mud left over, except this plant. It is so pretty, and it spreads fast, but not out of control. I could easily remove it if needed, and I move clumps all over the yard to help it spread. I grow it on steep hills and flat paths that we walk along.

In Calgary, Alberta Canada I have planted this plant beneath my Usurian Pear and it is coming along but certainly not aggressive. It is late June and it just beginning to take hold in year 2. Hopefully next year it will have a better spring.

This plant is terribly invasive. Not only does it spread like wildfire, but it chokes out other plants in its path. Once the horse is out of the barn, good luck getting it back in. Very difficult to control.

We love our Sweet Woodruff. It is just outside our front door, at the base of a spruce tree. The warning, (above somewhere), of putting it within 100 ft of anything else is ludicrous. we have several other plants within 10 feet or less, (though It is in a somewhat isolated plot). You can put the dried leaves in with woolens in summertime to keep moths away.

This plant grows well in my raised herb garden, which is really a huge container (12' X 4' and 3' deep) my husband built me). It seems to keep the mosquitos away. It is easy to move, so I am putting some on the shady side of the house. Here's hoping it does as well - because there is nothing over there but some sweet bedstraw. My mom is German & she likes having this plant around, remembering it from her childhood. She calls it Waldmeister, Master-of the- woods in English.
Invasiveness of this plant may depend on variety. I LOVE mine and it spreads, but is certainly not invasive in my z7 area. It's very delicate, so it doesn't overwhelm anything, even if it grows around it. I have had some invasive weeds that look like sweet woodruff and may be a wild variety, but are lankier and much harder to control. Be sure you're getting the Galium odoratum and that it's from a reliable source.
I love this plant. It's delicate and pretty. Lovely ground cover under my hostas, bleeding hearts & oriental lilies on the North side of the house. I've yet to see if it drives out my columbines and astilbes but so far so good. I transpanted it to the West side of the garage last year and it's already peaking out in zone 4.

I have had Sweet Woodruff on the east side of my house for almost four years. I planted a small flat after the second year I moved patches to help fill in the side. It has spread some but not to the point of being invasive. Now that it is established I rarely water it and it can tolerate light foot traffic. It is surrounding taller plant and acts like a living mulch.

Well, let's see if I can add a Northerner's note to this (I'm in Toronto, Canada).
I just planted 6 of these under a big old tree on my townhome's front yard last night. I am hoping they do spread as it is very difficult to grow a decent patch of grass around the tree. I had to add a bag of topsoil around the tree first as I couldn't find soil deep enough for me to plant them in -- the tree roots were all in the way. I did loosen what soil I could prior to putting the topsoil on.
I'm not too worried about it's invasiveness because the cold here will kill just about everything but dandelions!!

I have had this plant for at least 10 years. Some years I have a lot of it and some years very little. It's far from being invasive. It is growing under a large oak tree with lots of pebbles, small stones, and tree roots - hardly any soil. There are some happy hostas there also. None of it gets watered. This year it finally occurred to me to transplant some of it to a shady area with dicentras. So I'll see how it does there.
I planted two small plants in a raised bed in part shade last year. This year it is spreading rapidly, but is pretty easy to remove. I am transferring it to a treeline on the border of our property where nothing but weeds grow, hopefully it will like the clay soil there as much as the amended soil in the bed. Looks great in bloom, but watch where you put it!

We have not found this plant to be invasive in part shade (east side of our house) in zone 7b. In fact, I wish it would spread a little more. It has spread some. It is semi-evergreen here, and is a nice ground cover. I definitely give it a positive rating.

I love this plant - but I will admit that we joke that only invasives thrive well in my yard.
I grow it in the garden space at the bottoms of my gutter outputs - one side in pretty dense shade, the other is in a mostly sunny area. The Dense shade part is doing fabulously and looks great mixed in with my bleeding hearts and columbine.

I wish my sweet woodruff was invasive. I planted 18 plants in a bed with 3 PJM rhododendrons. The bed is nearly full shade and circumscrbed by our deck and concrete walks so spreading was not a concern. 3 years later, there is one tiny sprig left--not a single sign of any of the other plants. The soil had been amended a full season prior to planting.

I planted this a few years ago in full sun on the south side of our house. I had just pulled the overgrown bushes and was replacing them with small flowering foundation shrubs so these plants didn't have nay shade. The first year they struggled to stay alive and I know that I lost a few due to the hot sun and dry conditions. The next year they came back and really took off. Last year I thought a few more had died at the end of the summer but it seems like they have come back. I can see how these could be invasive but I like that they are low maintenance. Another note is that I didn't amend my very heavy clay soil where I planted these.

I agree. The sun-shy 'Sweet Woodruff' is an herbal groundcover likely best suited for colder climates, where it won't spread too vigorously. There's some in my gardens that has been growing (divided numerous times) over a span of nearly 20 years, and has yet to require more than a few hours' management (mostly for division) per season. It also stays green underneath the snow in wintertime. Sometimes I'll clear away a square foot's worth in the fall and plant a biennial like stock or foxglove smack in the middle of it, and the Woodruff won't grow back fast enough to choke the biennial before it's had it's 2-3 year run. It's too bad that gardeners in warmer climates can't get away with that. 'Sweet Woodruf' is a real treat when it's so manageable, what with it's charming early spring blooms, delicate fragrance, hardiness and herbal uses. Gardeners in warmer zones with loamy soil might want to consider it for areas where they want quite a bit of pretty groundcover for woodland-style path borders and such, though.

I'm in zone 5 and I planted it in the shade under some large trees so it really hasn't become invasive here. It doesn't have much room to spread too much and I really love the plant. If you put it with larger shrubs and trees it can't really take over.

Makes an attractive ground cover, and behaves itself in poor to average soil. If it gets into good soil in my region (6B), it can grow out of control, and requires a lot of attention to prevent it from getting its webby roots in the way of other plants. Of the groundcovers in my area, only certain types of lamium and Waldsteinia fragarioides can compete with it.
It smells great when it blooms, and its flowers are used in Germany to flavor/scent young riesling, called Maiwein (May Wine).

Spreading quickly in clay/loam soil and the shady side of part shade. So much so that it's crowding out the periwinkle. very dense atractive leaves for a ground cover, with well displayed white flowers in spring. Only downside it that it dies back in winter to leave a bare patch.
I found it very easy to pull out unwanted clumps by simply inserting my hand beneath it, as the roots are very shallow. I can imagine this might be more difficult in denser soil.

The trick must be to grow this plant in terrible conditions. I planted three in midsummer, lost one right off the bat. The other two are holding their own. They are planted in almost full sun and very, very poor clay soil. I can bearly keep them alive and there is not danger of them invaiding anything but the compost pile if they don't make it.

Zone 6b - A few sprigs planted 5 years ago.. now have put some in shade, full sun, amended and non-amended heavy clay - have found it a well-mannered ground cover....has spread wonderfully without choking anything out... beautiful looking foliage and DELIGHTFUL when flowering... flowers appear to be floating above the foliage... will try the car air freshener trick - thank you!

I love this herb. At my old house, I had it growing in poor (clay) soil, in almost full sun. This was too much sun for the little guy's liking (it lightened to yellow-green instead of staying a rich dark green), but it still bushed over the next couple of years and produced the multitude of tiny white star flowers. I never found it invasive.
A couple of sprigs thrown onto the car dash and left to dry make a wonderful vanilla-scented car freshener! The scent brings back good memories of summertime road trips. :)

The porousity of the soil seems to be the key to this plants' invasiveness. I have planted it as a groundcover in 4 different areas. My native soil is very heavy clay. In unamended soil, sweet woodruff barely survives. In moderately amended soil, it spreads a little, but is very polite in its tendency to weave.
In very rich, humusy soil, it has obliterated several other plants, including hosta, astilbe, and is currently trying to choke out a Philadelphus (mock orange) shrub. It is even making inroads on ajuga and lamiastrum (the unimproved one). Now if I could only train it to overwhelm the poison ivy...

This may be invasive if given great loam and ideal conditions, however in my zone 5A (actually 4B on the north side, where it is, I have found it to be a wonderful, good-looking ground cover around my foundation evergreens. I did NOT amend the soil when I planted (you know what midwest clay is like, I'm sure!) and it has behaved very nicely - frankly MUCH nicer than vinca, which I spent 3 years getting rid of all the runners! If you don't want it someplace, grab a shovel and dig a hunk! It's that easy! It has NOT taken over any other perennials, or bulbs that are companion planted. It seems to go around!

Let me underline the invasiveness warning! My mom gave me some, as it didn't grow much at her house & it's pretty. Also if you search the herbal type pages you can find all sorts of neat herbal uses. But we have found it to be Terribly Invasive... growing over vinca, little perennial flowers, and even taking over the mint. We have it in a shady area with a little fairly decent soil over rock, and I guess it loves it. The fragile stems make it a nightmare to try & pull out, you don't get the whole root and travelling vine. Be very careful with this one!

I understand that this plant may be invasive in damp climates or sites. However, in my garden in the high desert, I'm very happy to see it spreading under a large cherry tree, where it receives more shade than many other plants like. I haven't found it detrimental to the plants nearby: aquilegia canadensis, violets (another invasive--maybe they've just called a truce!), forget-me-not, even campanula persicifolia in a small nearby bed to which the woodruff is "trickling."
It also is a nice addition (dried) to potpourri as well as pleasant(fresh)in May wine.
About seven years ago my sister decided that my garden was incomplete without sweet woodruff. For the first three years I was pleased with the ground cover and fragrance. After that the plant went nuts and began to choke off everything in its path. I am now pulling it out to save what I have left, although the plant still persists. Warning: Do not plant this invasive unless you have nothing else that will grow within a 100 ft radius. I am not exaggerating; this thing travels.

The seed is slow to germinate, so it is best to divide
