Common Name: Yellow gum, Blue-gum, White ironbark (just so there is no confusion!)

Size
  • Nursery Notes 2019: Autumn

    Mature stock which we have grown on for a couple of years. Potted on now into a 20 litre pot or planted out, they will very likely begin to set flower buds in 2020.

    Description, habit,  uses and attributes:

    In short: a small tree suitable for mild climates, summer patio pots and winter conservatory or garden room.    Essentially a red flowered species which may occasionally throw either pinky-red or pink bloom.   The leaves are highly fragrant, producing a great deal of oil and are distilled for the production of cineole based eucalyptus oil.

    In Australia, E. leucoxylon is regularly planted for windbreaks, shade, honey production and for ornamental purposes. 
    Lignotuber: yes (which is a very good thing). The tree will grow back if cut down by man, beast or nature and also responds well to pruning and coppicing.

    How to use in the landscape and/or garden:

    • Good Specimen Tree for the wider landscape/for the smaller garden with a caveat:Eucalyptus leucoxylon 'Rosea' appears to take down to  -5°C, so far as we can see.  So if you draw a line between Gloucester and London and you live below this line, you may get away with growing Eucalyptus leucoxylon 'Rosea' outdoors, especially in a sheltered position.  We have a friend who grew one in Kent very successfully until the exceptionally bad winter of 2010, when he did finally lose it (and we lost a whole host of other plants such as Ceanothus and Viburnum, but we are still growing them in our gardens). Likewise the Chelsea Physic garden had a very substantial specimen of Eucalyptus leucoxylon 'Rosea', until that very bad winter.   Other parts of the UK: we recommend that you experiment, be a garden pioneer and take a risk: grow it outdoors in a sheltered spot, knowing that you may have to fleece it over in a bad winter (and even lose it) OR  
    • Patio Pot: if you are more cautious, grow it in a patio tub and move it to a greenhouse of conservatory for the winter. But isn't it worth the effort to see if you could get those precious red flowers?
    • At Grafton Nursery:  we over winter our Eucalyptus leucoxylon 'Rosea' in an unheated ventilated polythene tunnel, barely moist and they seem happy down to -5°C

     

    Shoots 'n Leaves: Shoots round and non-glaucous

    Juvenile foliage: matt blue -green, with high concentrations of the essential Eucalyptus oil, cineole.

    Adult foliage: matt green (sometimes glossy) and lanceolate to falcate (lance shaped to sickle shaped) and around 6-18.5cm long

    Bark: Smooth and tactile, mosaic colours of chalk white to clotted cream through to  gold and french blue.  Does not always shed completely, leaving some applique in pewter and coffee. On mature trees, the bottom 1-2m can be rough textured bark, before the smooth bark rises.
    Flowers: RED!  Nearly, but not all plants will produce red flowers. Some of the other subspecies will throw traditional white or deep pink flowers and you cannot tell until they bloom for the first time.  However, the seed of red flowered forms like Eucalyptus leucoxylon 'Rosea'  usually produce red flowered seedlings, so we are hopeful that our seedlings will flower luscious, exuberant scarlet.   Please keep in touch and let us know the flower colour of your tree!  Large flower buds up to 1.6 cm wide held in groups of 3, followed by large flowers and fruit.

    Leaf Aroma: strong, very high essential oil content (cineole)
    Rate of Growth: slow for a Eucalyptus tree, less than 1m per year

    Height in maturity, if left unpruned:  Eucalyptus leucoxylon 'Rosea' is  a dwarf subspecies growing to around 10 m in the UK, but given exceptionally warm sheltered conditions, could grow taller.  Best kept as a large pruned shrub in the UK, if you are going to move it around in a pot.

    Hardiness:  classified as not hardy, but our trees tolerate down to -5°C.  I guess it all depends on your soil moisture and local growing environment.  Should be happy South and West side of the UK where it is milder and also below the Gloucester/London line, also mild island climates. 
    Planting Position and Soil Preference: 

    Location: if you live in a mild climate with little or no hard frosts/exceptionally bad winters, then do give this species a go outdoors. (see notes above).  Otherwise, grow your Eucalyptus leucoxylon 'Rosea'  in a large pot and keep pruned, moving it to a greenhouse or conservatory over the worst of the winter months, but only after it has experienced a little light frost.

    Eucalyptus leucoxylon 'Rosea' likes a well drained but moist soil to begin with, but once well established, it will tolerate periods of drought.  Very happy in hot dry summers.  Eucalyptus leucoxylon 'Rosea' will grow in a wide range of pH from acidic through to alkaline soils.
