Germination is very difficult.
Out of 500 seeds only about 20 germinated, and the first year the plants are very small with tiny flowers.
The second year they are growing bigger and not spreading.
Here, in the second year they are not invasive (yet).

Btw, the last picture with the 2 dogs made my day :)

I see many people dislike this plant but it came with the house and I love it. It is growing out of the lava rock bed next to the house and I think it looks fantastic all by itself, even when not in bloom it smothered weeds and was a nice green ground cover until late winter. It looked like crap then until it got green again. I think the sidewalk keeps it from going where it shouldn't, wish I could spread it to my weed choked (non-native) hillside, but haven't had luck yet. I noticed baby rabbits and toads hide in it.


On Sep 6, 2016, iwong51 from Lexington, KY wrote:

Accidentally discovered a way to control this weed and improve its bloom season. In the spring, wait until it starts to sprout up before mulching right over it (2 inches of bark). The plant will eventually poke through the mulch but it takes a surprising amount of time (several weeks) and the new growth is thinner and appear in patches (rather than the solid swath). You can then pull out the patches in areas you don't want. The plant grows surprisingly slowing during this time. This will also delay the bloom time. However, because different shoots recover at different times, it will also spread out and extend the bloom season.

I no longer plant this species, and I try to eradicate it where I find it in clients' gardens.

It spreads very aggressively by underground stolons, which are hard/impossible to remove from the crowns of other nearby perennials. It isn't a plant for the mixed/perennial border. I find it jumps root barriers, probably by self-sowing.

It does respond well to 2% glyphosate herbicide, but to control it you may need to sacrifice any other perennials in whose crowns it may have taken up residence.

It generally doesn't grow taller than about 12-18"

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.

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... read more

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.

Invasive. Invasive. Invasive. I hate it! Pretty on the outside--evil on the inside!

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!

If anyone has had success in eradicating this weed that is promoted as a desirable drought tolerant xeriscape perennial please post it here! This plant is terrible.

It is a contstant battle. I've been pulling it out for 3 years now. I have tried Spectricide weed killer and that merely slows it down. Please HELP!!!

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.

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.

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.

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.

Small bees collect pollen from the flowers, but are unlikely to pollinate them. The size and length of the stamens and stigma suggest that hummingbirds, large butterflies, or day-flying Sphinx moths are more likely to pollinate the flowers while seeking nectar, although I have not observed this.

This has always been my favorite Texas wildflower since childhood.

I'm hoping it will be as "invasive" for me as it has been for the others here on the board. The area I plan to sow it in is a "wild" part of my yard, not my true flower garden area, so I will let it wander naturally around the area as it grows and reseeds and such. Wish me luck!

Can be invasive, but is pretty in naturalistic, or wildflower plantings. Can be planted in the perennial border, but deadhead or look out for the seedlings. Easy to grow in more difficult parts of your yard. Thrives in poor soil, (don't overfertilize). A good xeriscape plant. A pretty, durable plant.

This is my favorite wildflower (south TX) and it comes back every year in the same spots in my yard. It has never been invasive. Maybe that's because over the years, different people have cut my grass for me and no matter what I tell them, they cut most of these flowers down. So I count on the same patches coming up again every spring, and they never have a chance to spread. Maybe next spring.

I'm new to CA - zone 8/9.5, and found this flower beautiful and easy to grow. YES it is invasive. I planted it next to lavender, which it blends with nicely, but towards the back of a weedy, non-developed hinterland where it can go where it wants. I haven't had a long experience with it, so I'll report back after a couple of years.

I have observed the plant in different places (different plants) in colors ranging form white to palest pink to a deeper pink.

Here in Texas they are a wildflower, and bloom from April to end of May; after that they do not appear until the next spring.

To control invasiveness (which I do NOT consider it to be since it is only arund about 1 1/2 months per year or less),
but if you think it is so, they can be mown down to control.

In my own case, husband just mows them down much to my chagrin. I would rather them reseed and expand the next year.

The flowers glow at dusk. Beautiful plant.

This plant has been growing in my garden for the past 5 years. It was originally 5 seedlings that I planted and I had always worried about it not coming back. It is interesting to know that in some areas it can be evasive. It is a nice addition that I look forward to every spring.

I also like this plant. If you don't mind pulling it, to keep it under control. The flowers are beautiful. It's a great potted plant.

Although the plant blooms beautifully in Arizona, we have discovered a problem with this particular plant. We have it planted near our koi pond and it has grown so much that it started invading the water in our creek. After all 15 of my koi died I consulted a pond specialist who informed me that the stems secrete a type of poisonous resin that is toxic to fish. We have since cut the plant away from the water and haven't lost our newest fish as of yet. I'm not still totally convinced of this explanation, but felt it best to share.

Invasive weed! I can't get rid of it and it never blooms as nicely for me as in the pictures posted here. If it would bloom and look nice in hot weather, I could forgive it, but it just looks scraggly.

I like this plant, I can see where it can be invasive (even in zone 4) but if you put it in a area you don't mind it spreading in (a enclosed area) and it has to compete with other invasive plants it works well. The flowers are very pretty.

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.
