This Atlas cedar is more vigorous, thus the name 'Robusta'. The tree will become a large specimen with ascending branches that are bright yellow over blue-green leaves. An excellent 'coning' specimen, displaying many large upright cones along the branches in summer into fall. Best for gardens with plenty of space for this one to grow, maturing at 30 ft tall x 20 ft wide. Developed in Holland in the 1930's. Hardy to zone 6.
