Pea Hyacinths

I'm no gardener, so what time I do spend in the garden tends to be taken up getting rid of the weeds that have grown in the time I've not spent there. These pea hyacinths seem to take up a disproportionate amount of the time I do spend there, but would have completely taken over if I didn't pull them up, hoe them, spray them and do whatever else I think of to unsuccessfully try to get rid of them. They do make quite a pretty Blip shot though.
