Does anyone know what this plant is which is growing on the surface of a potted plant. I think it might be some sort of clover, in which case is it helpful? I know that clover can provide lots of nitrogen to the soil it is in?
Yeah I think it might be! oxalis vulcanicola seems to be it. Anyone know anything about it, I'm guessing it's not helping the rose in the container then?
Don't know what it's botanical name is Charlie but I can tell you it spreads everywhere and is a pain to get rid of.Not sure about it being oxalis though Fishy?
Oxalis pes-caprae aka Bermudan Buttercup (not West Indian nor a buttercup though) is one of the worst weeds worldwide. It seeds all over the place and it has tiny bulbs on the roots which detach when one pulls it out.
Sadly weedkiller is the only effective treatment.
And its seeds are almost impossible to kill, they can and do survive the heat used to make peat free compost, so you are importing it whenever you use that.
Charlie - I have such a problem with Oxalis corniculata in my garden. I have spent hours carefully loosening the earth and trying to pull up all the roots (unsuccessfully). Someone I spoke to said he thought the oxalis often arrived in bags of peat. The seed pod is a sort of explosive type so it spreads everywhere.
I have this in my garden and don't find it too much of a problem.Looks lovely in the right place?
A quick spray of weedkiller will get rid of ones you cannot remove manually.
It is a weed I can live with!
Here it is with a toadlet.
I guess that just shows that we all view plants differently, for my part I do my best to get rid of this one!
