I have a number of beds in a "wild" lawn, I wish to keep the lawn this
way as I love to see what wild plants grow. However my beds are
becoming infested with a weed that spreads through its root system. I
suspect that when I clean the beds any little bit of root grows and
develops into plants, anyway, if not, it certainly spreads in from the
surrounding grassed area. Firstly can someone identify it please from
these photos? I have attempted but failed. Hangs head in shame.

Secondly any suggestions for control? The only thing I can think of is
to edge the beds with a gravel path keeping that free from weeds with
weed killer, however maybe the roots would travel underneath the path.
