For Koala Bears There are said to be some five hundred
species of Eucalyptus, but the following would be my selection of the
hardier and ornamental varieties, some hardy down to minus 15°C and some
to minus 18°C. Others are more suitable for conservatories or mild
locations. Grown readily from seed (this is the only way to propagate
them as cuttings are almost impossible to strike), and best planted the
following year while still young. Eucalyptus do not like root
disturbance and should be carefully pricked out, either very early at
the two leaf stage or later, when the plant will handle the shock
better. They will need staking and are notorious for falling over,
partly because of their fast growing nature and being evergreen they
suffer from winter storms. The trick is to stake them very low down
allowing them to bend and strengthen but holding the roots steady. |

Eucalyptus caesia magna (Pr Pkt) £2.17 JS2091 |
||
|
A smaller species with silvery grey
leaves on pendulous white frosted branches and contrasting reddish
stems. The buds and fruits are large and glaucous, the flowers are pink
to red and nearly everblooming. This species needs good drainage and is
drought resistant. It is reported to bloom at 5 years of age and large
gumnuts making this an attractive specimen. Moderate frost tolerance to
about -5°C once mature. |
|||
 |
Eucalyptus cinerea (Pr Pkt) £1.66 JS1254 |
||
|
An attractive eucalyptus with silvery, rounded leaves often used in dried arrangements. A small tree or large shrub sometimes reaching 40’ and more commonly seen in florists arrangements. Tender though not tolerating much below -5°C. Good for a cold greenhouse and it can be pollarded to produce sprays of young shoots for cutting. |
|||
 |
Eucalyptus coccifera (Pr Pkt) £1.66 JS911 |
||
|
An attractive tree to 25m that makes a good specimen. One of the most cold hardy eucalyptus that will grow in a wide range of soil types and in most situations. Extremely hardy and frost tolerant. Smaller leaves and slower growing than some, a useful eucalyptus for the smaller garden. |
|||
 |
Eucalyptus
dalrympleana |
||
|
A really beautiful tree with pale grey to white mottled bark turning a spectacular pink and grey late summer. At -15°C in an exposed position this tree appears very happy. The sight of a full grown tree covered with hard frost in mid winter or covered with snow white blossom in spring makes it one of my favourites (the bees love it too!). The blue/grey adult leaves are long and scythe like, very often showing red tints on the old leaves - but again beware, this is a fast and large growing tree although the canopy is thin and graceful. |
|||
 |
Eucalyptus
deanei « |
||
|
A very beautiful, large Eucalyptus, with smooth attracive bark in colours of white, yellow and red, and pink-tinged juvenile foliage. Extremely fast growing and adaptable. Not fully tested for hardiness in the UK, but it will probably tolerate -10°C to -12°C. A UK customer told me about this variety who said that it was growing very well for him so well worth a try. |
|||
 |
Eucalyptus
debeuzevillei |
||
|
Similar to Niphophila and a sub species of pauciflora but with more of a robust look, the stiff blue/white glaucous leaves are larger and the bark attractively mottled. Smaller twigs have a distinct white/blue blush. This very attractive tree is said to be the hardiest, and so far I have never observed the slightest scorching of the leaves down to about -15°C |
|||
 |
Eucalyptus
erythrocorys |
||
|
For a good yellow flowering Eucalyptus this is one of the most spectacular with flowers up to 7 cm across. The flowers are preceded by large rectangular scarlet buds, hence the name, followed by large fruits that can weigh the tree down. Foliage is dark green and sickle-shaped. The bark is creamy with a few rough brown patches. Not a large tree therefore suitable for container growing and hardy to about -5°C. |
|||
 |
Eucalyptus
ficifolia |
||
|
If you have a micro climate that supports only a couple of degrees of frost you have to try this one! All of the hardy eucalyptus have white flowers, but overseas there are some lovely red flowering varieties, this being one of the hardiest. The flower bunches are about 6" across, and appear all over the tree in terminal racemes. My own tree shown in the picture is grown in a cold greenhouse but I would just love to be able to plant it outside. An excellent subject for the cold conservatory. |
|||
 |
Eucalyptus
glaucescens |
||
|
This is a lovely Eucalyptus fairly hardy to -15°C. My tree came originally from the US as seed in a mixed packet and we now collect our own seed from this beautiful tree in our garden. The long adult leaves are particularly glaucus and of a pale shade of blue grey with a hint of mauve not seen in many other hardy eucalyptus. I finally managed to identify our tree in 2004 from pictures found on the internet. Collecting seed was becoming difficult as the tree became larger but the storms in Jan 2007 brought a large part of the tree down enabling us to collect more seed! |
|||
 |
Eucalyptus
globulus |
||
|
Another excellent summer bedding plant for tropical effect, with large leaves of a stunning silver grey. Many years ago I grew this tree outside in London where it survived several winters until cut down by a hard frost even though it was by then some 30' tall! Over wintered after the first year in a well lit conservatory it will put on an excellent show the following summer bedded out. If you have space in a warm microclimate though do try it out of doors as it will take about -5°C to -8°C once established. The plant in the picture taken in August is in its first year from seed from a late May sowing, an earlier sowing should produce a 4' to 5' plant by the end of the summer. |
|||
 |
Eucalyptus
gunnii |
||
|
One of the best known gums for the UK garden, with
smaller adult leaves, a most attractive eucalyptus with bright blue
white leaves and silvery young branches. It is very hardy and again has
never shown signs of any frost burn in my own garden. The adult leaves
are also less scythe like and more rounded in shape. |
|||
 |
Eucalyptus
leucoxylon megalocarpa |
||
|
Eucalyptus Leucoxylon (Subspecies Megalocarpa.) – is an
excellent small gum tree with large red flowers through autumn and
winter with large decorative fruits up to 2cm long. It usually grows to
between 6 and 10 metres high in its native habitat, with a short trunk
and a spreading crown, but probably smaller if you can find a place to
grow it in the UK. It is a very hardy red flowered form suitable for
most soils and climates including costal sites and sand. Capable of
withstanding frost down to about minus 7°C it makes an excellent
ornamental tree for a sheltered light frost location. |
|||
 |
Eucalyptus
leucoxylon petiolaris |
||
|
Eucalyptus Leucoxylon (Subspecies petiolaris.) – another
excellent small gum tree with large red flowers through autumn and
winter with large decorative ribbed fruits up to 2cm long. It usually
grows to between 6 and 10 metres high in its native habitat, with a
short trunk and a more open crown than megalocarpa. It is a very hardy
red flowered form suitable for most soils and climates including costal
sites and sand. Capable of withstanding frost down to about -7°C it
should make an excellent ornamental tree for a sheltered light frost
location. |
|||
 |
Eucalyptus
neglecta |
||
|
A very hardy eucalyptus we think to
-20°C. It retains the large round juvenile leaves on square stems for up
to 7 years from seed with a lovely purple blue hue to the new growth.
Becoming very popular in the US as a small versatile Gum! |
|||
 |
Eucalyptus
niphophila |
||
|
This tree is known as the snow gum because of its native
habitat above the mountain snow lines. The tree has a definite white
bloom to the leaves and the grey white bark is augmented by the white
flower clusters produced in the spring, as shown in the photograph. The
leaves are of a heavier make up than other species, able to stand severe
frosts. This is one of the hardiest and most attractive species to grow
although slower growing than some. |
|||
 |
Eucalyptus
nitens |
||
|
Grown mainly for a wood crop in Australia because of its fast growth and hardiness, replacing Globulus in colder areas. However it has very large ornamental leaves similar to Globulus and is proving hardy in the UK even as a young tree. If you have room it should make a stunning display, but even as a small tree the juvenile leaves are very ornamental. |
|||
 |
Eucalyptus
nitida « |
||
|
This tree has attractive shiny green adult leaves, is fast growing, reasonably tolerant of adverse conditions and hardy down to about -10°C to -15°C. The younger foliage has more of a typical grey/blue Eucalyptus hue and smell strongly of peppermint. |
|||
 |
Eucalyptus
papuana |
||
|
IWe have included this famous tree after many customer requests. The Australian Ghost Gum, Eucalyptus papuana, is also termed the “widow maker”, due to the high number of pioneer tree-felling workers who were killed by falling branches, as they shed whole and very large branches to conserve water during periods of drought. Slow growing with stunning pure white bark, it will only tolerate frost to about -5°C, but ideal for a few years as a small conservatory tree? |
|||
 |
Eucalyptus
pauciflora |
||
|
An excellent Eucalyptus with large stiff blue/white glaucous leaves and attractively mottled bark. Smaller twigs have a distinct red/orange tint. This attractive tree is very hardy with superb bark markings and as the tree develops the branches start to weep under the weight of the large leaves. |
|||
 |
Eucalyptus
perinniana |
||
|
Known as the spinning gum because of the juvenile foliage that encircles the stems. As the tree ages they dry up and break free from the growth point still encircling the stem and “spin” in the wind hence the name. I prefer the adult foliage with long scythe shaped leaves hanging attractively on the branches. The bark of the main trunk has more of a mottled cinnamon colour rather than silver or grey. One extra benefit is the sweet scent when in flower, like burnt cinnamon, that permeates the garden and the bees just love it. |
|||
 |
Eucalyptus
risdonii |
||
|
This rare Gum, from a small area of Tasmania, has intensely blue, stem-clasping juvenile leaves which smell of peppermint. Grows quickly into a small tree. It has smooth bark and is quite floriferous at maturity but unfortunately only hardy to about -8°C. |
|||
 |
Eucalyptus
rubida |
||
|
A beautiful tree, not quite so hardy as the others but nevertheless surviving frosts to about -12°C with just a few burnt leaves. The new growth in spring has a lovely lilac tint as you can see from the photograph and as the weather cools down the older leaves can take on quite a reddish hue. The young deep red stems are also quite glossy which adds to the overall attraction. |
|||
 |
Eucalyptus
sideroxylon rosea |
||
|
The "Rosea" form of the Red Ironbark
is a seed selection that is red flowering. In all other attributes, it
is identical to the species, but typically will grow slightly smaller.
The growth is normally upright on juvenile trees, but trees begin
spreading with age and can become 15m high and 15m wide. The bark of
this tree gives it its common name; Red Ironbarks have deeply fissured
plate-like bark that is a rusty red beneath and black on the surface.
This bark contrasts well with the foliage, which is dark green to
grey-blue. Frost hardy we think to about -6°C |
|||
 |
Eucalyptus
urnigera |
||
|
The urn gum grows in a small area of southeastern Tasmania. It grows at altitudes up to 900m, often on steep rocky slopes of mountains in sub alpine woodland. Easily grown and excellent for ornamental planting with young leaves displaying a distinct purple hue and excellent bark markings. |
