... and more...

My first sighting of this little alien was on a "quick walk up Pen y Fan":

New Zealand Willowherb

Epilobium brunnescens

Probably spread by walkers' boots I suspect.

And this isn't that uncommon but a recording scramble at Craig y Rhiwarth this year provided the perfect opportunity for a photograph that shows all (?) the Orchid flower "bits".

Broad-leaved Helleborine

Epipactis helleborine

And the local speciality - visible from our window in theory - if you had a good enough telescope...

Meadow Saffron

or Naked ladies

Colchicum autumnale
