    MYRTACEÆ; Myrtle Family

    Common Name: Silver Cider Gum

    Status: Evergreen Tree                  

    Origin: French Plant Breeder Luc Harvengt

    Dwarf compact hybrid

    Easy to grow

    Amazing intense silver pewter blue foliage

    Can be kept as a small bushy shrub from 1.2m upwards

    Grow as a statement compact standard in your garden

     

    Description, habit, uses and attributes:

    Eucalyptus gunnii ‘Silverana’  is a fabulous new small to medium Eucalyptus tree ideal for the smaller town garden

     

    Lignotuber: probably not as it is vegetatively raised.

    However, if pollarded to around 1m, dormant epicormic buds will sprout from the trunk, on young trees.  Mature trees may not be able to re-sprout.

    How to use in the landscape and/or garden:

    How to grow or train it to get the best out of it

     

    Good Specimen Tree for the wider landscape, arboretum collection or avenue planting and for the small, medium and larger garden:

    Growing a full sized standard: planting the tree and running away is an option, but it won’t necessarily give you the best results.  For information on how to do it properly see our ‘Help’ pages here - hyperlink to help page

     

    Growing shrub-onna-stick clipped standard: this is an opportunity to grow a Eucalyptus in a confined space and control its overall size. You can produce a small tree on a trunk with a height of anywhere between 2.4m (8ft) and 4m (12ft)

    See our ‘Help’ pages here - hyperlink to help page

     

    Growing a multi-stemmed rounded bush or tree.  Eucalyptus gunnii ‘Silverana’  responds well to coppicing and readily produces a multi-stemmed specimen

    Why would you want to do this?

    To create:

    - Screening: to grow a tree with more body or ‘mass’ of branches and foliage for screening purposes. Once grown back up to its full potential, it will now have several main trunks with many branches carrying lots of leaves.

    - Interesting form:  to create an attractive multi-stemmed architectural tree, especially if it has exceptional bark

    - Control height: usefully maintain your Euc anywhere between 2.4m (8ft) and 7m (20ft), but genetically it will want to grow taller if ignored.

    To produce your own multistem from a young tree or maxi tree see our growing notes here - hyperlink to help page

     

    Floral Art:  Eucalyptus gunnii ‘Silverana’ has all the hallmarks of being great for cut foliage and will be added to our ‘Cut foliage’ list.  We recommend harvesting prior to the hard winter frosts to avoid tip burn. Summer harvesting may be an option; this is being evaluated in our trials.

    For information on how to grow cut foliage, see our ‘Help’ pages here - hyperlink to help page

     

    Firewood Production:  ‘Silverana’  is not on our selected species list for Biomass or Firewood. 

    For information on how to grow firewood, see our ‘Help’ pages here - hyperlink to help page

     

    Hedge-Screens & Windbreaks:  Eucalyptus gunnii ‘Silverana’  is an excellent choice for a hedge-screen as it readily produces sub-lateral shoots – i.e. branches off the side-branches and easily becomes bushy.  This is unusual for most Eucs.

    For information on how to grow hedge-screens, see our ‘Help’ pages here - hyperlink to help page

     

    Rural/Agricultural:      

    - Good shade tree for livestock to stand under.   Eucalyptus provide a cool environment for horses, cattle, llamas, sheep to shelter from the sun on hot days, as the mass evaporation of water through the leaves creates a cool shady canopy beneath. Also, I have been told that the eucalyptol in the leaves deters flies. Best grown in a group of trees to provide it with protection from exposure.

     

    Ecology:  

    - Bees. All Eucalyptus produce flowers with nectar and pollen. Eucalyptus ‘Silverana’ usefully flowers in June/July providing foraging for honey-bees and other pollinating insects 

    - Habitat creation and Game Cover:  this species lends itself to providing good trouble-free habitat creation for wildlife and game cover, when planted in groups of trees.

    Birds enjoy roosting in Eucalyptus trees and Pheasants like rootling around underneath them.

     

    - Chickens: The shredded foliage of Eucalyptus ‘Silverana’  is excellent at keeping Chicken nest boxes and hen houses free of red mites, which detest the presence of Eucalyptol. I used to line our Chicken boxes with shredded leaves, strew the floor and pile up the spindly branches for the chickens to make nests.  It was all great till the foxes moved into the next field L

     

    Environmental:

    - Growing on the Coast  We have no experience of growing Eucalyptus gunnii ‘Silverana’  in a coastal environment.  I suspect it may do well in milder coastal districts, when grown a mile or two inland of the sea, but this needs trialling.  Do get in touch if you are giving this a go and let us know how you get on.   

    See ‘Help’ pages for further details on growing in coastal locations here: hyperlink to help page

     

    - Drying up wet soils.  We have no experience as yet of growing Eucalyptus gunnii ‘Silverana’  in seriously boggy ground, but will be trialling it.  I suspect it will prefer a draining clay soil rather than swampy

    - Tolerance of cold and exposed growing environments inland  Eucalyptus gunnii ‘Silverana’ requires a degree of shelter from other plants to grow in an open location. No grass, no weeds and a thick bark chip mulch, to a depth of 150 mm (6 inches) are essential to assist with good establishment

     

    - Tolerant of poor stony soils once established   Eucalyptus gunnii ‘Silverana’ does not require a rich soil and can survive in poor, stony soils.   It is essential that your Euc. is given lots of water during its establishment phase, before you abandon it to its fate.  The tree needs to establish a good, deep root system before it can survive in these challenging conditions.  No grass, no weeds and a thick bark chip mulch, to a depth of 150 mm (6 inches) are essential to assist with good establishment

     

     

    Pot Culture outdoors: 

    Eucalyptus gunnii ‘Silverana’  is an excellent subject for container growing especially as a multi-stemmed shrub. Pot on at the recommended intervals and feed and water copiously during the growing season. Lack of water will result in it becoming brown and crispy…not a good look!     

    Over winter conditions for Eucalyptus – protect from frosts at around +5°C, provide protection, good light and water twice a week.

    Biometrics

    Shoots ‘n Leaves: Eucalyptus gunnii ‘Silverana’ has fabulous foliage. Young shoots are intensely silver and white

    Juvenile leaves are typically rounded like its parent E. gunnii

    Adult leaves are long and lanceolate like its parent E. gunnii

     

    Bark: typical of E. gunnii group – peeling and flaking with age. Young bark is silvery. We are waiting to evaluate the mature bark in the nursery trial plot

    Flowers: White, in small clusters in June/July time

     

    Leaf Aroma: moderately strong on warm days – typical Eucalyptol

     

    Rate of Growth: medium 1.0-1.5m (3-4ft) per year, but faster the E ‘Azura’ 

    Height in maturity:  Eucalyptus gunnii ‘Silverana’  responds well to regular annual pruning on March 18th  to keep it small, either as a bushy shrub or shrub-onna-stick. If maintained as a coppiced/pollarded specimen, it will take on the size and shape of a Pittosporum shrub or coppiced Hazel tree. 

     

    Without pruning to control its size: Eucalyptus gunnii ‘Silverana’  will become a medium sized tree, moderately fast, growing up to about 10-12m tall  (30 ft-ish).  

     

    Hardiness: tolerating down to around -10 °C to -15 °C mark, once mature. 

    Protect from severely cold biting winds and bad winter weather for the first few years (3-5 years from planting).  Get it well rooted into deep soil is essential for this species, for it to thrive…see our planting notes.

    Hardiness in Eucalyptus is governed by provenance/genetics, how it is grown (i.e. high nitrogen levels reduces cold tolerance), age of the tree - the older your tree, the hardier it will be. Younger Eucs are more susceptible to frost damage.

     

    Planting Position and Soil Preference:

    Full sun

    Shelter: enjoys a sheltered position – not that keen on exposed windy locations

    Preferred soil type: any normal garden soil that is free draining: stoney/dry, clay, loam and normal range of pH acid-neutral-alkaline.

    Drought and cold resistant once established with a deep root system.

     

    To encourage deep rooting and therefore good stability, prepare a deep planting pit as per our instructions.  If planting a large number for cut foliage, subsoiling may be a good practice to follow, especially if pastureland has previously been used by livestock.

     

    For the best results, follow our planting and aftercare watering instructions; issued with every order.

    For the first few years of establishment, the breeder recommends a 20cm mulch of bark chips over winter.

    Tip burn:  even on older plants, your Eucalyptus gunnii ‘Silverana’  may experience frost damage and wind scorch on the finer filigree-like shoot tips. This is easily removed during Spring prune – March 18th

     

    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.

     

    Meaning of the name: ‘Silverana’ refers to the intense silvery foliage
