Sorry for all the links, but this weed has been the bane of my life for
30 years. I *may* be just starting to see its grip loosening. I've
even risked planting that part of my garden again (except for one
corner). Previously, I've never dared move a wanted plant from that
area of the garden to another for fear of spreading it. I dream of the
day I never see another leafy spring rosette. Pedipalps crossed.

Oh dear. TBH, I've never heard of this weed being found in the UK
before. I must lead a very sheltered life.


There's a largish colony by a canal bank a couple of miles away from
me, but it's scarce of much of the country. It tends to be
southeastern and coastal.
Cheers, Jake
=======================================
Urgling from the East End of Swansea Bay. We don't yet have a
"dah dah dah dah dee dee deeee" theme tune but we're working on it.


There are a couple of recorded sites at the east end of Swansea Bay,
but there could be less than 50 sites in the whole of Wales.


It would appear that Spider has a rarity and should now go into high
reverse with eradicating it!! I've never seen it before and thought it
looked quite attractive...





You wouldn't think that if you'd lived with it for 30 years! It is only
pretty when in flower, and that is when it is most dangerous. Although
most of those links suggest hoeing is *eventually* effective, I haven't
dared take a hoe to it for fear of chopping up the root and spreading it.

We also had Japanese Knotweed when we moved in. I managed to eradicate
that (although I note it's approaching again from a rear 'garden'), but
Whitetop is horrendous. Don't wish for it. There are plenty of other
white flowers .. Ground Elder, for instance ;~)).
