    Botanical Name: Eucalyptus gunnii 'Azura' (Cagire) PBR     MYRTACEÆ; Myrtle Family

    Common Name: Cider Gum 

    Status: Evergreen Tree

    Origin: French forestry breeding programme AFOCEL from E. gunnii parents

    Why we like this variety:-

    • Slow growing for a Eucalyptus (still fast for a tree)
    • Intense, beautiful, silvery blue foliage 
    • Very bushy habit
    • Highly prunable and exceptionally frost hardy
    • This is it .....the perfect Eucalyptus!

    Description, habit,  uses and attributes:  We think this is the most exciting discovery in the Eucalyptus world for a long time and we are thrilled to be able to offer Eucalyptus gunnii 'Azura'in our collection.

    The French Forestry Commission have a breeding initiative to find new Eucalyptus hybrids for timber production and E. gunnii 'Azura' is a product of this programme.  Obviously, if you are breeding and selecting Eucalyptus for timber you want a no messing incredibly vigorous, fast growing, straight stemmed tree with no side branches.  'Azura' did not meet these criteria at all, as it is compact, extremely bushy and slow growing for a Euc.  Fortunately for all of us, the French recognised the ornamental qualities of 'Azura' and now we can plant it in our gardens.

    E. 'Azura' has E. gunnii parentage and exhibits all of the benefits of E. gunnii with amazing rounded silvery blue foliage and non of the overtly vigorous side affects.
    Already in the nursery, we can see its seriously bushy nature, much slower growing and more compact  than the other members of the gunnii clan and appears to have a finer, more fibrous root-system: altogether better behaved!

    Lignotuber: yes. If cut down by man, beast or nature, Azura will regenerate off the stump. See my blog post on lignotubers. Responds well to coppicing, pollarding and cutting with secateurs and shears.

    How to use in the landscape and/or garden:- 

    • Good Specimen Tree for the wider landscape and also for the smaller garden where you require a smaller bushier evergreen tree of a very hardy nature.  E. 'Azura' could be planted as an avenue, where straight  E. gunnii would simply grow too large.    'Azura' will look fabulous in a mixed border, bringing cool silvery blue to the planting scheme. An excellent structural evergreen tree or trimmed shrub for the winter garden.  Try planting E. gunnii 'Azura' with red stemmed Cornus alba 'Westonbirt' or team it up with Cotinus coggygria 'Royal Purple' and Phormium 'Maori Chief'.  Great addition to xerophytic gardens and those with mediterranean or australian planting themes.
    • Floral Art: can be used domestically for cut foliage, but I suspect it is not vigorous enough for commercial production
    • Hedges Screens Windbreaks: would look great planted as a hedge/screen. Its dense habit will make a great privacy screen and the silvery blue foliage will reflect light, making it difficult to see beyond the screen.     Prune in spring, with 2-3 dry days forecast, to an 'A' shape, to keep it bushy down to the ground. Avoid pruning Eucs during wet weather, to discourage fungal attack.
    • Pot Culture outdoors: Eucalyptus gunnii 'Azura' is an excellent subject for terrace pots and large planters or raised beds. See our notes on growing Eucs in pots for compost, feeding etc.
    • Houseplant: given a very sunny and airy garden room or conservatory, with low humidity, early indications are that E. 'Azura' could make a good indoor plant. We are carrying out trials and will let you know the results.

    Shoots 'n Leaves: Young shoots are covered in silvery white wax

    Juvenile foliage: rounded, intense silvery blue

    Adult foliage: intermediate foliage is elliptical and then the foliage will change to the typical lanceolate E gunnii foliage as the tree matures; however the internodes are very short, giving a bushy appearance. Regular pruning will encourage the rounded juvenile blue foliage.

    Bark: Smooth bark in pewter grey, cream, olive or sometimes pinky brown, flaking off in large pieces to reveal new bark in shades of pale gold or creamy silver.

    Flowers: white flowers followed by gum nuts.

    Leaf Aroma: typical strong Eucalyptus fragrance
    Rate of Growth: slowish for a Eucalyptus. In the nursery, they have grown about 30cm (1ft) over 4 months, so will possibly grow 60-90cm (2-3ft) in an average year.  We will update this page as we gather data from our nursery trials.

    Height in maturity, if left unpruned:  Current estimates are that E. gunnii 'Azura' will reach 5m (15ft) tall by about 2m wide,  in the medium term and approximately 10m (30ft) in the long term, may be taller in exceptional growing conditions, but still less than half the finished height of its parents.  Remember, E. gunnii 'Azura' is a versatile, much bushier tree than straight E. gunnii; reminiscent of a Pittosporum in habit and can be kept trimmed to form a small tree or 'shrub-on-a-stick' for the smaller garden.

    Hardiness:  in the region of -16°C  Exceptionally hardy for a Eucalyptus

    Planting Position and Soil Preference:  Enjoys and needs full sun for compact bushy growth. E. gunnii 'Azura' will grow in a wide range of soil types from moisture retentive clays, deep fertile loams to free-draining stoney ground; any soil pH of alkaline, neutral and acidic persuasion. Follow our planting instructions (issued with each order) for the best results.  Water with 1-2 gallons of water per week for a minimum of 8 weeks after planting (from March to September), depending on the weather.
    Make life easier for you and your new tree: Plant with the mycorrhizal fungi product Rootgrow.  Eucalyptus in particular have a special, lifelong relationship with their root fungi, the latter of which actively transport food and water directly into the tree roots, helping your new Euc establish faster and more efficiently, particularly in challenging types of soil.
