The beeches and maples are, of course, major trees, tall at maturity, while the dogwood and hornbeams are minor trees. Wherever the gradual replacement of avenues of tall trees is a requirement, these climax species are the ones to use. The following charts give some useful groups of tree species and clones for a number of climatic zones. Crimson King is not hardy in this zone. Other clones are fine.
Plant strains of northern origin only.
Good for poorly drained sites. Plant strains of northern origin only. Good for replanting where an old avenue is being renovated. Autumn Purple is an especially colorful clone. Marshall's and Summit are fine clones.
