Aaaarrggh!!! I hope it isn't syn. Pilosella aurantiacum, but I fear
it is. A few treasured plants in my wildflower lawn spread seed like
good'uns; I, in loco proud parentis, let some grow on in flower-beds,
till I realised what I'd done. The wild-flower field guide didn't
mention the runners...
I love the thing; but not in captivity.
