hello, i have a weed quickly taking over my yard.....now even showed up in a pot on the back porch. i have looked and cannot identify....any thoughts? what to kill with? earlier in the year i sprayed with ortho "weed be gone" to get rid of dandilions....those are gone but now this has taken over.
invasive weed taking over - zone 8a
We have always had those things but I've never known a name for it. We always just pulled them up. It would probably take some kind of herbicide for woody plants to kill it. I'll be interested to know what the name is.
Jim.
I have them everywhere too ... including in my pots on the deck. They look like little mimosa trees but they're not. I just pull them up too. It's not hard. Roots aren't deep. Have no idea what the name is.
I guess they are something common to our climate. Looks like we are all pretty close zone wise. I'm in 8a.
There are certainly worse weeds to be worried about. This one is a nuisance but not aggressive and nasty like some. Any weed killer would probably get rid of it ... even the "Gardener Guy's" vinegar and water, if you don't like commercial weed killers.
The weed that gives me the most trouble in the flower beds looks like a tea weed. The only difference is the ones in the beds pull up easy. The tea weeds we use to have in cotton and soy beans had a deep tap root that you couldn't hardly pull up.
The bane of my existence is smilax. Nasty, nasty. Bites. Grows almost as fast as kudzu. Hides in the middle of a shrub then pops out at night when you're not looking. The next morning there's a cute (?) little viney thing waving at you from the top of the bush. Deep, bulbous roots. Yuk!
they are the "Mimosa tree" we have a huge mess of the at the back of the proprty line and they blow their lil seeds every where I hate them as well same little tree folks .
if left alone they will take root and grow to be a problem
Sarge
No, it's not mimosa tree--it has more finely divided leaflets. This looks like a Senna/Cassia of some sort--there are several weedy species--if you let it bloom it might be easier to figure out which one.
thier done bloming in the back i think i can take a photo of the Big tree if that will help solve the Tree issue though
Sarge and their are the close by too so we can compair them to and solve the mystore .
Im game :>0 i still dont like them either way lol
It is not mimosa although it is similar to a mimosa seedling. These things will get a couple of feet high if left a lone but that is all. You can still pull them up easily at that height. Hope someone knows the common name. I have heard it but it slips my mind. Or maybe this plus 100 temp has burned it out. When the ole man comes in and stays it is hot.
It is really similar Sarge but not the same thing.
so 3 diffrent trees ?
Gardening101. That is most likely the Sensitive Briar ( Mimosa microphylla) There several species of Sensitive Briar, but that one seem to be the dominant one in the southeast. http://davesgarden.com/guides/pf/go/56502/
Thank you Farmerdill
You have Cleared the air and the Mystery of the Nuasance little plant.
Many Thanks

NO IT NOT!!! Its Called chamberbitter or mimosa weed. I have them and they are a bane to get rid off. took one to the county extension office. they are a pest. http://www.google.com/imgres?imgurl=http://www.aragriculture.org/Images/weed_id/chamberbitter.jpg&imgrefurl=http://www.aragriculture.org/horticulture/ornamentals/weed_id/chamberbitter.htm&usg=__e0dZwKO6lMnyHmH31EChglxjpYk=&h=225&w=300&sz=17&hl=en&start=1&um=1&itbs=1&tbnid=PCTlCG6CBPmyVM:&tbnh=87&tbnw=116&prev=/images%3Fq%3Dchamberbitter%26um%3D1%26hl%3Den%26client%3Dfirefox-a%26sa%3DN%26rls%3Dorg.mozilla:en-US:official%26channel%3Ds%26tbs%3Disch:1
Possible, But Phyllanthus urinaria does not have mimosa type blossoms like the Sensitive Briar http://davesgarden.com/guides/pf/go/71283/. The briar is also sensitive in that its leaves fold up when touched. Both are pests so good luck.
Sarge,
If you click on Farmerdill's name, it will bring up his page. You can send a private D-mail from there.
Sarge I think your second picture is a Sumac. At least that's what I know it as.
The third looks like a Paradise Tree to me. A real PITA!
Actually sumac is too. some people have allergic reactions to some sumacs like poison ivy so be careful.
Tylersays,
Thats Mimosa grown Tyler sorry thats wher the seed are comeing from
Sarge
Sarge--your trees don't look like Mimosa trees to me either. Here's a pic of mimosa leaves so you can see what the leaves look like--see how the leaflets are further subdivided into even tinier leaflets? http://davesgarden.com/guides/pf/showimage/32389/ I agree with Tylersays that yours look like Rhus (sumac) or Ailanthus (tree of heaven) or something along those lines. If you're not sure, I'd post them in the ID forum, lots of experts there who can tell you for sure what they are. (Rhus and Ailanthus both spread readily by seed too just like the mimosa tree does)
I HAVE to agree - aside from the first photo, which may be a mimosa, but is probably the weedy type mimosa that blooms yellow, the other two are most definitely NOT mimosa.
Here are some sumac pics:

The more I look at it I think the second picture is just a young Paradise Tree
thanks everyone for the replies!
Farmerdill, i think you are correct in identifying this for me "That is most likely the Sensitive Briar ( Mimosa microphylla) There several species of Sensitive Briar, but that one seem to be the dominant one in the southeast"
when i touch the leaves........within minutes they fold up.
now.....how to get rid of Sensitive Briar ( Mimosa microphylla)? it is spreading quickly..... and i want to get it in check soon! keep in mind......in the mid 90's here today if that matters.
co-op it called Eraser put it on the plant only just a little follow the lable
Sarge ;>)
My guess is Chamberbitter, Gripeweed a.k.a. Phyllanthus Urinaria. I agree with Farmerdill
I think yours is Sesbania herbacea--but you might want to consider starting your own thread for it to keep things from getting confused. http://davesgarden.com/guides/pf/go/68448/
My friends call it nuisance/gripe weed. It is prolific. I do use chemicals, and Roundup kills it with repeated applications. I admire those who pull it up, but I'm just too old and lazy.
I wish you well.
I think the original picture and the plant taking over Gardening101a's yard might be Mimosa Pudica... I will post a picture.
I'm also in relatively the same climate and its all over the place.. I have found it in pots as well.. Its is shallow rooted and very easy to pull up.. but if you shake it to save some of the soil, you shake seeds back into the soil.. and you know what happens then....
Mimosa pudica has a fairly limited distribution within the US (and does not occur in AL) so I think it's unlikely that's what your plant or gardening101's is. If it's a Mimosa species, it's likely M. microphylla as Farmerdill had suggested above which is one that actually does occur in AL. http://plants.usda.gov/java/profile?symbol=MIMI22
I don't know about "Mimosa microphylla Dryand. - littleleaf sensitive-briar MIMI22, the leafs look and behave the same..but I have never seen ones we have here bloom or have briars...
Once when we were at Mobile Botanical Gardens for a plant sale, my husband picked one out of a plant pot because he thought it was a tiny Mimosa Tree.. He asked one of the specialist and she told him it was a weed called Pudica. She is the one who told us not to shake the soil off because its spreads the seeds.
Although this link contradicts me on the flowering part... It does show that it grows in some regions of Alabama.
http://www.associatedcontent.com/article/1491160/mimosa_pudica_shyness_grass_sensitive.html?cat=5
I'm still not insisting I'm correct, because as I said, I have never seen them flower.

If you check the reference for the "growing in Alabama" part of that article, they are citing the Plant Files page where someone from AL has put in a zip code report saying that they are successfully growing this plant. I'm sure that it can be grown in gardens in AL, but it does not occur in the wild there (per the USDA) so it is unlikely that it would pop up on its own in someone's yard. http://plants.usda.gov/java/profile?symbol=MIPU8
After a good nights sleep.. and rereading this thread...I see, ecrane you are correct about my reference. Those locations seem to be "added in". So for the ones that grow on my property I am going to lean toward imzadi's entry of:
Common Name: Chamberbitter
Scientific Name: Phyllanthus urinararia
Weed Type: Broadleaf
Life Cycle: Summer annual
It seems to have most of the characteristics of mimosa pudica minus the briars and blooms (as I mentioned earlier)....As FarmerDill said, it only gets a couple feet tall at the most. I also see in the picture, in the plant files reference, the seeds that we were told its important NOT to shake of with the soil.
So for me.... I'm considering it SOLVED.
Thanks ecrane. : )
