My beautiful tree with a greyish bark and unusual vibrant pink and green leaves was the favorite of all visitors, Noone knew the name of tree until I took a branch to the nursery and the owner said it was a beech tree . The branches had buds this year which never opened - I opened one bud up and inside, indeed, was a combination of colors - a potential Leaf. When I scratch the branches - they are green under the scale. The tree is in partial shade - but it is an old tree - as it is over 15 feet tall with many branches. It did not frost in May ( to my knowledge) - I guess I can check with the weather bureau - and it rained sufficiently here in Pittsburgh. The tri-color beech shares the back yard with an old Japanese Maple which is doing just fine. I did plant more perennials around the beech and a bush at its base did grow in breadth . Did the beech need more space ?? The nursery owner said : your tree is dead if it has no leaves ." Why did it bud then stop ?? I am deeply saddened - is there anything I can do ??
