Cornus kousa var. chinensis. Chinese Pagoda Dogwood
Chamaecyparis nootkatensis 'Pendula' Weeping Nootka False Cypress
Last but not least:
Rhus typhina Staghorn Sumac (very showy in the fall and has a spreading tendancy)
These are my choices for 2008. They are specimen trees and have special needs. If you have any questions about these trees email me.
