i love this plant, very showy with its flower starting white and then turning pink. ofcourse is invasive, but easy to pull out(dont we have trouble with Dandelions twice a year :) ). has a light fragrance, planning to start a new bed under my birch tree and it can overtake the lawn(which looks very bad because of the huge tree and shade) ofcourse i have others under the tree, tickweed, lirope, anemone peony, pink butterfly bush, big leaf hydrangea, astilbe, ajuga, creeping phlox, etc

I planted this in a few of my raised brick beds last year as a mid-summer space-filler. In a matter of a month the runners were everywhere and overtaking everything even with diligent management. Flowers resulted in seed germinating nearby and quickly expanding its reach through all types of soil, plants and even robust turf-grass. I tried digging it up to no avail as even the tiniest remaining rhizomes quickly produced new plants. I was eventually forced to commit plant genocide with commercial strength Round-Up - which took not one, not two, but FOUR applications to finally kill the stuff. Heavy doses of pre-emergent and diligent watching of the affected areas will hopefully rid me of this menace once and for-all.

When I lived at my old place, my next door neighbor had them growing along the front of her house. I thought the pink flowers were rather nice.
Then I moved away and had gardening space on all four sides of my new house. On the west side, there were the cute little flowers. I decided to plant roses along that side, and weeded and cleaned the strip thoroughly, pulling out tendrils that were easily 2 feet long. I then covered the area with 6mm black plastic. I left it that way from January till the bare rose sale in November. I removed the plastic, no primroses, yea!! and planted the roses with gazanias behind them.
I put in my sprinkler system, put in a pretty little fence and watered the roses regularly. Suddenly I began to see tendrils coming out from under the house and beyond the fencing. They were back, tangling themselves in with the gazanias and on the march! I pulled them up, as much as I could since they break off at the soil level, and cleaned up the area again. Over and over again.
This has been a 2 year fight and they are winning. I pull them out and they send in their secondary troops. They lay on top of the gazanias and flatten them. Evey now and then, I'll see a pink flower about 8ft away, but aside from that, they never bloom. I can't use an eradicator because of the roses and gazanias so I just keep pulling them out.
I think I hate them. I tell myself that the bending and stretching is good exercise, but , yes, I hate them.

Native in my area of coastal South Texas. Evening primrose, often called "butter cup" even though it's pink. Noninvasive in its native environment; I don't recall ever having to pull one out of my garden more than once and never in my lawn. (No ground cover herbaceous plant survives competition with a watered, healthy, Saint Augustine carpet-grass lawn.) Creates an attractive carpet of pink flowers in fields and pastures during our hot, dry summers. Drought & heat resistant and thrives in poor soil. Another case of a plant that can go rogue outside its native habitat.

Be sure you and your neighbors are ready to have it everywhere! It was planted by my builder's landscape company all over my front and back yard and I am pulling it out daily in the hopes that I can get rid of it for good. It sends runners underground and pops up everywhere--in grass, from under large rocks, in far away locations too. Maybe it is also reseeding? I've only had it 6 months, or so, and it has covered anything near it. No need to spend money on it, just grab a sprout from some other poor victim and watch it take over.

Before you plant this, be sure you love this crazy thing--and don't plant it anywhere near my house!

As stated multiple times, this can be invasive. However, it doesn't "choke" out other plants, just grows around them (in my experience). It just grows low around things as a filler. I found my cherry bells campunula to be more invasive. The deer like to browse it, which can be controlled with repellent. I am having a problem with Japanese beetles this year (first time in three summers) and this is a favorite of theirs. But that gives me a good place to look for them when I want to drowned them! With so many blooms, the deer browsing and pests don't create that big of a problem. I also have it planted with lavender, dianthus, peonies. It is a nice addition to a cottage garden if you want a breezy, somewhat overgrown look.

This is a very drought tolerant plant and is great for a hillside or other dry areas where little else will grow. I use it along the strip next to my garage where the roof overhang and dry soil make it impossible to grow most other plants.

It is very easy to pull extras if it spreads too much.

If you shear it back to a few inches from the soil after blooming it will rebloom.

This is a beautiful plant that spreads like the devil. (1 year+2 plants= covered about 40 sq ft) I resorted to letting it bloom and then cutting it all the way to the ground every year. In northern wet climates like mine- best to plant as a groundcover underneath eaves, so that it gets very little water. It is a little tall for an underfoot groundcover. Mine also has some interestingly variegated foliage and looks nice in the fall (although I usually pull it before then.) If this plant were a movie character it would be like the magical broom in Disney's Fantasia because it comes back as a million plants from every little bit of root.

Positive chunx On Jul 9, 2005, chunx from San Diego, CA wrote:

For Southern California, it's good for dry banks and areas you seldom water. Mine starts blooming in early March and goes until we get a light frost. HOWEVER....You need to trim these plants (a little beyond deadheading) to keep them blooming well. They reseed and spread to the point of becoming invasive, so only plant them in areas where most other stuff won't survive without ample water. These plants look a lot better than the typical iceplant you see here, but like I said, it needs to be trimmed to look good, whereas iceplant requires no deadheading. After seeing mine growing, lots of neighbors have planted it on their hillsides. In the heat of summer, you will see them wilt to nothing and bounce back by morning. I shoot a little water on them once a week during that time and they come back and spread like wildfire.

Now for the BIG NEGATIVE - Do not do what I did and use it in an area of your flower bed that doesn't get much water. Although the seed packet said that it was extremely invasive, I became a moron and thought I could handle it. It looked great the first year when I started with 2 plants. It filled in the area nicely. The second year, it took over the entire flower bed and choked out my petunias, lavatera, and just about everything else. I got so tired of pulling out the plants by the handfuls only to see it emerge from seedlings within days, that I sprayed the entire flower bed with Roundup and repeated the process 3 weeks later when the seedlings emerged. It took care of the problem, but I had to replant everything. The more water, the faster they spread to the point of taking over the world.

I pinched a single sprig from a basket at a neighbor's house 3 years ago, stuck it in the ground (without a thought) outside my front door, and now it's everywhere, despite all of my best efforts.

This plant (or a near relative) grows wild along the road in Kansas. I often admired it, and finally stopped to dig some for my garden. I live on 14 acres, so it could actually be pretty invasive and not bother much. I suppose it is proof of my inability as a gardener that I could not get it to grow. It lived for one year and then died out. I think I may have had it in soil that was too rich, considering it does so well along roadways where the soil can't be all that good. I will probably try again and locate it in some really sandy, poor soil.

This plant has taken over my garden, and I am constantly trying to weed it out. I have tried everything to rid my garden of this plant, but it comes back.

DURABLE...!! well suited for use in sidewalk medians/cracks/crevices as it tolerates mowing. Can be very invasive though removal by pulling seems effective.

To propagate in frost-free regions, dig up and replant bits of the rhizomes showing sprouts near the end of dormancy. Plant in containers to control rampant spreading.

It can be a nice filler plant, but it WILL take over if you're not careful. I thin this plant by the handfuls several times a year to keep it in check.
