The letter O represents Oak tree.

A symbol of strength and endurance, the mighty Oak has made its way throughout the UK. As the national tree for England and Wales, as well as the emblem for County Londonderry in Northern Ireland, the British people are somewhat smitten by the Oak with the Scottish particularly fond of storing their fine Scotch Whisky in barrels made from the tree.
