Magnolia virginiana 'Henry Hicks': 'Henry Hicks' Sweetbay Magnolia1

Edward F. Gilman and Dennis G. Watson 2


Magnolia virginiana `Henry Hicks' is a graceful southern evergreen with a wide columnar habit, ideal for use as a patio, tree, or specimen. It remains evergreen well into USDA hardiness zone 6, maybe 5b. It can grow to a mature height of 40 feet in the north or to 60 feet in the south. Trees glimmer in the wind due to the whitish-green undersides of the leaves. They are very noticeable as you drive by them on interstates along water-logged woodlands. The tree provides excellent vertical definition in a shrub border or as a free standing specimen and flourishes in moist, acid soil such as the swamps in the eastern U.S. and along stream banks. The creamy-white, lemon-scented flowers appear from June through September, and are followed by small red seeds which are used by a variety of wildlife. It can be trained into a multi-trunked, spreading specimen plant, or left with the central leader intact as a wide column.

Use and Management

Sweetbay Magnolia makes an excellent tree for planting next to buildings, in narrow alleys or corridors, or in other urban areas with limited space for horizontal crown expansion. It has not been planted extensively in downtown urban areas, but its flood and drought tolerance and narrow crown combine to make it a good candidate. It usually maintains a good, straight central leader, although occasionally the trunk branches low to the ground forming a round multi-stemmed, spreading tree. Should be grown and planted more often.

Sweetbay Magnolia roots easily from softwood cuttings, grows freely near coastal areas, and is happiest in southern climates. It is thriving in the Auburn Shade Tree Evaluation trials in Alabama without irrigation. However, in the confined soil spaces typical of some urban areas, occasional irrigation is recommended.

The species is deciduous in USDA hardiness zones 7 and 8 (evergreen farther south) but the variety australis and cultivar 'Henry Hicks' are evergreen; 'Havener' has larger flower petals.

Pests and Diseases

Scales sometimes infest foliage and twigs, particularly on dry sites where the tree is under stress.

Tulip-Poplar weevil (sassafras weevil) feeds as a leaf miner when young and chews holes in the leaves as an adult.

Leaf spots occasionally occur on the foliage but are of little concern.
