Hi, these trees are called Betula utilis var. jacquemontii - Silver Birch.

thanks for replying - birch grows large doesn't it? is there a way of keeping them this size?

Hi, could you tell me what type of wood the fence is made from?

Hi Gaz, this wood is western red cedar trellis.

Hi, unfortunately Silver Birch do grow quite large and this is something to take in consideration before planting them in your garden.
