	Plant list: Trees Trees are distinguished by the fact they have a trunk, however small, and a branch system. The largest living organism in the world is a tree General Sherman, a giant redwood living in the US.
	Betula pendula Silver birch Tree Hardy N/A Mid-green 15m x 7.5m to 9m (49ft x 25ft to 30ft) The plain silver or common birch, sometimes called 'the lady of the woods' because of its outstanding elegance, is a great landscape feature. When planted 60cm (2ft) apart, the trees make a fine hedge, or may be grown 2.4m (8ft) apart as a screen or windbreak, which can be trimmed each winter. Growth is upright, later slightly weeping, especially the young outer stems - trim shoots off the trunk to reveal the attractive bark.
