Plant ID please
Hi, I've been trying to find a previous forum user who, I think, sent a pic of this. In our woodland bit of the garden that is very overgrown I've spent today digging up nettles, brambles and a plant I haven't noticed before. I feared it might be Jap Knot Weed as it has hollow stems (this was the gyst of the item I was trying to find). Anyway, I've checked out the description of JKW and it doesn't appear to be that. So here goes. Can anyone throw a light on what this is and is it to be encouraged, tolerated or annihilated? It's not unattractive.
