Help identify a weed

9 Replies

In about six weeks a weed has almost taken over a fallow part of my veg patch, about 100 sq. mtrs. Its also appearing in amongts the veg. The stalk looks in its early stages like the growth one expects from a potatoe, dark green stem and leaves with a small white flower and tiny yellow centre. Thats where the similarity stops, as it grows upto about 3 or 4 feet high and forms a bush.   The flowers turn quickly into a green berry, which goes black like a blackcurrant very quickly. The plant by this time has a white tap root about 9 - 12 inches long. Very difficult to pull out without snapping the taproot. What is it, is it an annual or perenial, where did it come from as the veg patch was virgin grassland until this spring with cows grazing..Regards BobBaud (56) and Dwyran (LL61)

Sounds like one of the nightshades,v.poisonous.


hope you get rid

Wow, I'm glad you reported this.  We've got one of these in our garden (only about 15cm high at the moment).  It appeared out of the blue three or four weeks ago in between a hydrangea and some verbena and I've been watching its progress with interest, trying to fathom out what it is.  First time I've ever seen it and I cannot think where it has come from.  Ve may be right about it belonging to the nightshade family as the flower is similar in form.


If it does take over the ground as you report, I'd better pull it out quickly!

Thanks for the info.


Been looking on the internet. Seems to be the Black Nightshade. See here http://www.hdra.org.uk/organicweeds/weed_information/weed.php?id=27


Its an annual but the plant can produce 9000 - 10000 seeds.


It can survive in the soil for years and still remain 80-100 percent furtile.


Grows to maturity in 7 - 8 weeks, sometimes less.


I've strimmed the plants and intend to burn the haulms, regular rotovations should kill the seedlings as they appear......I hope.

yes this is none other than deadly night shade all of the above is correct. I would recommend you burn the whole plant root and all if you can. care ful when strimming you well spread a few seeds by the physical shaking of the plants.  THIS PLANT IS DEADLY TO ALL LIVESTOCK.

Yes we get them too. They pop up even in well established borders and gardens in between the shrubs and flowers and this year we have had a lot. As the others say, deadly nightshade so needs to be completely removed/destroyed.

According to the descriptions on the internet, it is NOT Deadly Nightshade, as the flowers and berries are the wrong colour. It is the Black Nightshade, its 'cousin'.


Black nightshade


(duscle, garden nightshade, hound’s-berry, mixplenton, morel, petty morel)


Solanum nigrum L.


Reading the information its stem and the unripe green berries are poisonous but their seems to be a difference of scientific opinion as to whether the black ripe berry is. Supposed to be eaten as a substitute for spinach in certain countries but those people may not be around to confirm this.

Many other poisonous members of its family which as a matter of interest includes potatoes, tomatoes and Aubergine.


Amazing what you can find out on the internet.

Time to get the roundup out.

Roundup is not the best method if it has set seed.  It does not kill the seed.  Better pull it out, it comes up easily.  Incidentally, deadly nightshade (atropa belladonna) is a pretty rare plant, I have never seen it growing wild.  Black and woody nightshade (red berries) are much more common.

Rosa you want to try and pull mine out, its like trying to pull out a dock, the tap roots invariably snap and your hand get covered in sap. Thats when the stem doesn't snap.


 


Having said that it appears its an annual so leaving some root in doesn't matter.


 


I have a couple of stacks about 4 foot high of the plants pulled our. I am going to burn them later this year. From info on the internet continuously working the soil after the seed germinate should eventually do the trick.
