'Gallissonniere' is a conical, evergreen tree with large, leathery, glossy, dark green leaves, reddish-brown and hairy underneath. Fragrant, creamy white, cup-shaped flowers are produced at the end of the branches from late summer to early autumn. Plant in moist, humus-rich soil. Some protection may be needed from late winter frosts. Magnolia pruning should be carried out in midsummer when in full leaf.
