Unknown plant help!
Hi everyone, just moved house, new to gardening, and now have a very large garden to look after. Can anyone tell me what this is? It seems to be spreading, roots spread horizontally quite some way by the looks of things, in flower beds and poking up through gravel (not sure whether it's forcing through the weed suppressing membrane or what). Some regular gardeners in the family that I've asked aren't sure what it is. Any help, including whether it's good/bad/benign, what to do with it, etc, would be appreciated - cheers!
