Eucalyptus Gunnii Azura

Eucalyptus gunnii Azura is a relatively new variety of eucalyptus. It was discovered by the French Forestry Commission when they were assigned the task of finding new eucalyptus varieties for timber production. Although the Eucalyptus Azura tree did not meet the French Forestry Commission's requirements of being a timber eucalyptus, it was recognized as a valuable garden asset. It quickly garnered praise for its ornamental qualities. Compared to more traditional varieties of Eucalyptus, Eucalyptus Azura is extra hardy and more compact and shrub-like in habit.

Eucalyptus Azura is a fast-growing evergreen tree. It reaches a height of 3 to 4 meters when mature. The tree grows approximately 60 to 90 centimeters per year until it reaches its full growth potential. It grows in a compact, bushy habit which makes it an excellent hedging or privacy screen choice as well as a good choice for evergreen borders. It features intense, bluish-grey evergreen foliage that has exceptional eucalyptus fragrance. The foliage can be harvested for flower arrangements or for drying. The young shoots and leaves are covered in a waxy, white powder substance until maturity when their full steel blue hue is revealed. The juvenile leaves of the tree are intensely blue. The bark of the Eucalyptus Azura is powdery grey. It does develop small white flowers during the summer which are followed by tiny gum nuts.

Plant the Eucalyptus Azura in full sunlight for optimum growth. When planted in shady locations it often becomes leggy and fails to develop its characteristic bushy appearance. It will thrive in virtually any soil type and is not picky about pH levels. Choose a planting location that is well-draining and not soggy. During the tree’s first year of growth keep its root system evenly moist. Once established it can withstand periods of drought.

During the spring months, the tree can be pruned to maintain its pyramid form and to encourage dense growth close to the base. Avoid pruning the tree during wet weather to discourage unwanted fungal growth. The Eucalyptus Azura has a fine, fibrous root system which makes it ideal for growing in large terrace pots. It can also be grown beside walkways, driveways and other built-up areas because its root system is non-aggressive.
