Kissing is still in fashion. Ulex europaeus, gorse

Gorse, furze or whin is a genus of flowering plants in the family Fabaceae, the pea family. There are several different species. Common gorse flowers a little in late autumn and through the winter, coming into flower most strongly in spring. Western gorse and dwarf furze flower in late summer (August–September in Ireland and Great Britain). Between the different species, some gorse is almost always in flower, hence the old country phrase: "When gorse is out of blossom, kissing's out of fashion".
