Birch comes of age

20110430 Metre birch catkin 020 

The birch tree that appeared from seed 7 years ago in spring 2004 in the south west corner of the Square Metre itself, has a few green catkins among its delicate leaves.

I estimate the tree is now about 6 metres tall.

These are the first catkins that have been produced and it shows how quickly birches can reach reproductive size from seed.
