Pinus strobus nana is a smaller variation of the larger growing Weymouth Pine or White Pine.
This has conical growth at first but later forms a bushy top.
The colour is a very attractive pale pastel green and the "nana" form will not grow too large making it perfect for the small garden.

My tree is about six years old but planted three years ago amongst a variety of Japanese maples including the very attractive bright red stemmed Acer palmatum Sangokaku.
