In 1998 we planted a grove of River Birch trees (Betula nigra 'Cully'). We spent a great deal of time figuring out just how to place them to get the perfect view from the windows of the house. All these years later I realize it was a wasted effort. The bark of River Birches is so visually compelling that I no longer see my forest for the trees. Given our continuing cool weather I'm happy to have my grove of beautiful Birches to enjoy since most of the flowers are still in hiding.
