Winter Heliotrope

It was really windy this morning, but thankfully this soon passed and by lunchtime the sun was showing it's face! 
I went for a quick trip out to find something (anything !) to blip, and on my way home I noticed this Winter Heliotrope Petasites fragrans growing on the verge. 
I found some of this last year growing in a church yard and was really pleased as I thought it was Butterbur, but it sadly wasn't!
Winter Heliotrope is a non - native species native to the Mediterranean region of North Africa, first introduced in 1806, and recorded in the wild by 1835.
It is a perennial, and unusual in the fact that it flowers in the winter, forming large persistent patches of round leaves throughout the rest of the year. It is dioecious ( male and female reproductive organs exist on separate plants) and spreads by rhizomes as only male plants are present in the UK.
The male flowers are pinky purple, smell of vanilla, and are an important early nectar source.
