The Butterburr (Petsites) I know grows on river banks and the leaves get huge. That is what had me fooled.
Thanks Nigel4ever, I think you have it. I have resorted to Glyphosate weedkiller where it was growing on its own, but where it is appearing in amongst other ground cover, it is a bit more trcky. Spot weedkiller it is.
Butterbur is Petasites hybridus, winter heliotrope is Petasites fragrans, and there's Petasites alba as well, that's probably the one I've got it's white, very pretty and I may live to regret it.
This lot are thugs whatever language you use.
I thnk the first one is celandine. If you dig it up you will find small nodules thta break off to make more plants. The leaves are just beginnig to appear now in my garden. I have tried mulching, digging, poisoning!, absolutely no joy to get rid of it. Alan T says almost impossible to remove, Did an article probably in GW about worst weeds to get rid of. Article may ahve been last year not this.
I don't think it's shiny enough or the right leaf shape/ manner of growth for celandine.
Agree about the invasiveness though
The first one looks like 'Jack in The Hedge' (garlic mustard) and the description matches. I have come up all over my garden has quite deep roots so be sure to dig deep and get it out before it seeds everywhere.
On an invasiveness scale of 1-10. Petasites and celandine are 10. Jack in the hedge possibly barely 1. It's a biennial, if you pull it up it's gone, the other 2 just ignore all your efforts
That said Alliaria petiolata may regenerate from adventitious buds on the roots. These may sit doormant in the soil for up to 18 months until disturbed and thus regenerating. Often classed as Monocarpic perennials rather than biennials because the foliage can remain for more than two years before they flower. All this in mind I think an invasiveness of barely 1 is a little off the mark.
As the proud owner of all these plus enchanter's nightshade I know which one I'd rather tackle. But; different problems in different gardens
Yes I agree definately not up there with some of the REAL problem weeds. Tastes good too and I for one love to have a good range of edible plants in the garden, this is one however that in my experience should be contained
I forgot to mention the creeping thistle. But no ground elder
The bit you'll like is, I introduced both the enchanter's nightshade and the petasites. The nightshade when I was too inexperienced to know any better. The petasites a couple of years ago when I did know better but didn't listen to my own advice.
