    There are three genera found in the Myrtle (Myrtaceae) family that may be considered gum trees: EucalyptusAngophora, and Corymbia. The last one used to be included in the Eucalyptus genus up until the 1990s, and you may still see that genus name used for them by some. They are called gum trees since many species ooze lots of sap if the trunk surface is damaged.

    The Sweetgums (Liquidambar spp.) and black gum (Nyssa sylvatica) are not related.

    Almost all of the gum trees come from Australia, where...MORE they are the primary food of koalas (Phascolarctos cinereus). Over time, they have been cultivated in other tropical regions around the world. There are gum trees that can even live in cooler temperate locations like Norway. In some regions, they are considered invasive species.

    Some gum trees form a lignotuber (underground root tuber with buds), often as a way to recover from fires. This tuber can produce new branches as needed. Trees with this structure are called a mallee.

    Oil from the gum tree leaves is used in a variety of medications. Honey is made by bees that visit the trees, and the wood from many of the species are used as lumber. Some people like to chew on hardened chunks of gummy sap.

    The species name ficifolia indicates that the leaves of this tree are like those found on ficus trees. Like many other species in the Myrtaceae family, the flowers are made up of stamens with no petals. This is one of the more popular species to be planted. It is a kind of eucalyptus known as a bloodwood.

    • Latin Name: Corymbia ficifolia

    Juvenile sprigs from this species are often used in the floral design industry, as are the young leaves of another species known by the same name (Eucalyptus polyanthemos). The silver dollar gum grows fast enough in one season to work as a large annual in cooler areas. 

    • Latin Name: Eucalyptus cinerea
    • Other Common Names: Argyle apple, silver dollar tree, mealy stringybark
    • Native to: Southeastern Australia
    • USDA Zones: 8-11

    The name scribbly gum is inspired by the tunnels left by the scribbly gum moth larvae (Ogmograptis scribula) as they burrow in the bark. Other species that can be affected by the scribbly gum moth (and known as scribbly gum) are Eucalyptus sclerophylla, Eucalyptus rossii, Eucalyptus racemosa,and Eucalyptus signata.

    • Latin Name: Eucalyptus haemastoma
    • Native to: Southeastern Australia by Sydney

    Snow Gum

    The snow gum is able to survive in cold regions, even where there is snow. This tree is NOT true to its species name - pauci- (few) -flora (flowers). As the Australian National Botanic Gardens mentions, a European botanist named Franz Wilhelm Sieber collected some flowers when he visited Australia and some may have gone missing from his collection or he might have come across a specimen that didn't have many flowers, possibly inspiring the name.

    • Latin Name: Eucalyptus pauciflora
    • Other Common...MORE Names: Ghost gum, white sallee, weeping gum, cabbage gum
    • Native to: Southeastern Australia
    • USDA Zones: 8-10
    • Height: 30-100' tall, depending on the subspecies

    The spotted gum is endemic to Australia and has lemon-scented leaves. The bark forms a spotted pattern. These are a favorite food source for rainbow lorikeets (Trichoglossus haematodus).

    • Latin Name: Corymbia maculata
    • Native to: Southeastern Australia
    • USDA Zones: Unknown;  likely 9-11

    More Evergreen and Tropical Trees and Shrubs


    I am partial to gum trees since they remind me of my childhood in Southern California and I do recommend them if they work for your situation. However,  if you want to consider other evergreen and tropical trees and shrubs, check out:
