DEFINITELY FORSYTHIA

OK - I got it...

Forsythia blossoms produce four petals which grow from scabby light brown stems - they're identical colour wise, to Winter Jasmine. But this one's blossom has five or six petals & it lives on a shiny virulent green stem with little rust spots.

Wanted to show you MS Jasmine on the same Blip but had to resort to an extra -  have to buy myself an English-speaking Photoshop - this French-speaking one is anathema to my intuitive mouse...
