Have spent the last few days digging these up from my garden. I wasn't too worried about them until they started growing up the side of the house through the broken pointing.
I poured some Jeyes fluid on them (only on the ones at the side of house as I dont want to affect any other plants) and it seemed to kill them off. But now new ones have started poking through the pointing, so i have ripped them out by the roots and scraped out the soil and put more jeyes fluid down and then re-pointed it.
Would just like to know what they are so I can deal with the ones that are amongst other plants and shrubs, as I dont want to kill all the plant life.
TIA
