At most times of the year, you can usually find
Red Dead-nettle (
Lamium purpureum) in flower - this one was in Frenchay Churchyard, sheltered by an old gravestone.
Not a flower, but
Spotted-laurel (
Aucuba japonica) is very well established in the Frenchay Hospital Nature Reserve, probably the result of a garden on the site before the hospital was built.
And, lastly, this photo won't win any prizes, but at over 100 feet away and on the other side of a river (which was far too deep to cross...

), it's the best I could do.
Japanese Mahonia (
Mahonia japonica), a single bush on the far bank of the River Frome in Eastville, Bristol. Like all the others, it's one I'd known about from last spring; maybe by using a telescope, though, I might manage to get a better picture
I'm still waiting for the first addition to my overall list (which currently stands at 1,380 species), that probably won't come until next month. By the end of this season, my ambition is to have photographed 2,000 species of plants in my folder - tough, but I don't think it's impossible
