Gorse

or whin, or furze, depending on where you are, is the 15th letter of the tree ogham. It's more of a bush than a tree, granted, but it earns its place by being in flower whenever kissing is in season, in other words, all year round! I make this bit of natural calligraphy on an extremely windy day, and I got extremely well scratched trying to keep all the prickly bits from blowing away. It's a member of the pea family, hence its beany seeds.
