I seem to have these all over the garden at mo. think they were the seeds (like dandelion) that blew all over the place from a nearby field from a huge tree! I have been pulling them up daily! Not sure of specie though.

Could be a willow herb

Dont think its the same leaf Mg. WH is much narrower.

I get these all over my garden even in the pots, its a weed very easy to pull out. I have never looked them up as I always assumed they were a broad leafed Willow herb?

Forget the 'herb' bit, I think that it is a willow tree seedling. It would have a woody stem.

I agree with Bulba - no "herb", but a willow. Could be a goat willow, they seed everywhere. In late spring the fluffy seeds blow all over the place and collect in great drifts like cotton wool. Get them all out while the roots are still short.

Thank you all. I was bought a shrubby willow tree in a pot . I have repotted it so perhaps it has seeded into another pot. Thank you.

I thought willow and then typed will herb!

Beattie that is the one, blessed nuisance it is!!! There is one in the field at the back of us and this year the seeds were like clouds all landing in my garden, I have pulled out dozens!
