I have been eyeing roadside patches of what I thought was 'this' - superficially similar leaves, but larger, to put in my wild patch. It was only when I recently found some Tussilago/Colt'sfoot in carpark gravel, flowering pristinely and yellowly in the first spring sunshine - a few roots have subsequently taken, leaves appeared - that I realised I had been conflating it with the larger relation, Petasites (Butterbur group)

which has larger leaves and mauve flowers

Silly me, but Tussilago will do until I find a rhizome or two of Petasites.
