If you mean white bark birch the inventory shows 2. Everything is listed alphanumeric botanically. Check the botanical name so you can find specifically what you are looking fr on the inventory. They have loads of trees. White birch is Betula utilis jaquamountii. River birch Betula nigra is also very nice and a native tree with shedding multi colored bark that usually does very well.
Lots of trees of many varieties. We just recently bought dogwood and spiceberry.
