Scientific: Corymbia papuana (formerly Eucalyptus papuana)
Common: ghost gum
Family: Myrtaceae
Origin: Found in southern Papua New Guinea, southern West Papua, Daru Island in Torres Strait and the northern parts of Cape York Peninsula, Queensland, Australia. It occurs as a component of savannah woodlands on flat or slightly rising and stony grounds.

Pronounciation: Cor-RIM-bee-a pa-pu-A-na

Hardiness zones
Sunset 12-24
USDA 9-11

Landscape Use: Highway plantings, large commercial and residential areas, shade tree, background silhouette, trunk accent, great for moon light gardens

Form & Character: Evergreen tree with a more refined character than red gum, very clean, stately.

Growth Habit: Strongly upright and pendulous, moderate growth rate to 60 feet in height (120 feet in height in north Australia) with less than equal spread, slightly rounded at top

Foliage/texture: Grey green to light green lanceolate leaves tapering to an acuminate tip; somewhat falcate, foliage hangs alternately in a unique, disparate, splayed plane; the trunk is deciduous, smooth, and off white with distinct ripples around the larger branch collars; medium texture, but slightly more coarse textured than E. camaldulensis because the leaves are slightly larger and wider.

Flowers & fruits: Small white summer flowers, inconspicuous, fruit pediculate, inconspicuous

Seasonal color: None, but this tree's excellent trunk characteristics should always be on display.

Temperature: Hardy to 22oF. Heat tolerant.

Light: Full sun

Soil: Tolerant

Watering: Moderately drought tolerant

Pruning: Elevate the canopy base (crown elevation) as necessary, train extensively when young so as to avoid having to later make large pruning cuts leaving gaping wound scars on this tree's otherwise very cool, smooth white trunk.

Propagation: Seed

Disease and pests: None

Additional comments: In the Phoenix area, ghost gum is a MAGNIFICENT substitute for red gum (E. camaldulensis) or other upright weaker eucalypts. Like its 'relational strong brother' coolibah (E. microtheca), ghost gum adapts very well to urban sites in the lower Sonoran Desert and is a high performance eucalypt of great versatility and usefullness in the Phoenix metropolitan region. Unfortunately, its trunk beauty is occassionally debased by local thugs and vandals.
