Petasites fragrans Winter heliotrope I
This plant, introduced from North Africa, has spread throughout Europe and forms large patches of heart or kidney shaped leaves. It is dioecious but only the male flowers are found in Britain and they have very short petals (rays). It isn't a very prolific flowerer and in spring, summer and autumn it only shows leaves. You could easily miss it flowering in months when some patches don't seem to in flower at all while others are abundant. Strangely for a plant which flower in mid winter it isn't very frost tolerant so severe weather in late December will kill off much of the "crop".P. fragrans smells of vanilla and flowers from November through to February but has mostly finished by March 1st.
Common in England, Ireland and Wales, Petasites fragrans has fewer significant sites the farther north you go and it is largely absent form Northern Scotland.
