In flower...

[David Entwistle]

I'm fortunate to be living in a relatively mild part of the UK. As of the
13th January 2025, we have the following, in flower, in the roadsides and
along the footpaths:

Allium triquetrum - three-cornered garlic.
Erigeron glaucus - glaucous-leaved fleabane.
Petasites fragrans - winter heliotrope.
Ulex europaeus - common gorse.

I've also seen:

Ficaria verna - Lesser celandine
