Abies koreana
Korean
Fir
|
Conical
conifer with darkish
green leaves. Produces purple-blue cones from an early age which are very
decorative. A well shaped and proportioned tree, to 30ft tall and 20ft wide. |
Tree |
Acer palmatum
Japanese maples
|
The
archetypal Japanese tree, usually bought as a small specimen 1-2ft tall. Not
tolerant to being exposed to cold, wind or full sun and best grown initially at
least in a container so you can move them about to find the best position. They
don't like chalky soils preferring it on the acid-side. Numerous cultivars
available, one of the commonest (and cheapest) being "atropurpureum"
which needs positioning carefully as it can appear rather dark and dense. The "dissectum"
cultivars are very beautiful with finely cut leaves. "Aureum"
has
plainer shaped leaves but a lovely bright yellow color. "Sango-kaku"
(senkaki) has bright coral-red winter shoots with yellow autumn leaves. |

tree / shrub |
Aucuba japonica
Spotted or Cuban laurel
|
Evergreen shrub, with glossy
leaves to 8" long spotted yellow. Plants are either male or female, females
have bright red berries in autumn. Tolerant of quite deep shade and indeed
requires some shade to be really happy. Will grow in difficult situations and
tolerant of dry soil. To about 10ft high and wide but easily controlled. Frequently sold as three or
four rooted cuttings in a pot, separate them and you instantly have more plants!

Shrub |
Bamboos
|
Bamboos are evergreens and not
affected by any major pest or disease in this country. They are not always able
to cope with exposed windy conditions which often makes them look a bit tatty
and threadbare. they all prefer dampish conditions and won't really withstand
being baked by the sun with little moisture available.
Arundinaria nitida (also
known as Sinarundinaria nitida or Fargesia nitida) - fountain bamboo,
is a handsome one with dark purple-green canes and dark green leaves, to 15ft
high by 5ft wide.
Arundinaria murieliae
(Sinarundinaria or Fargesia
murieliae) - umbrella bamboo is similar but more, well,
umbrella-shaped. Yellow-green canes at first turning yellow with age.
Phyllostachys
nigra - black bamboo is particularly striking with canes that start
green but then turn black in the second or third year 10-15ft high by 6ft
wide.

Shrub / perennial |
Betula spp.
birches
|
The
birches are admirable trees for small gardens, some types can grow tall
(eventually to 50ft or more), but they tend not to spread very far and have an
open canopy that gives a dappled shade, a lovely effect. They need an open sunny
situation. The native
silver birch Betula pendula is a popular choice, but the bark is rather
rough and splits with dark patches forming with age, go for named
cultivars such as "Dalicarlica" / "Laciniata"
or
"Tristis" if you can find them. I prefer the
Himalayan
birch, Betula utilis "jacquemontii" (usually sold as Betula
jacquemontii) or the paper birch,
Betula papyrifera. Both have a
smoother, brighter bark than the native species and are fairly easy to find. If
you have more space, birches can be planted as a triangular group of 3 about 3
feet apart. You tend to get a similar canopy as if a single tree was on its own,
but 3 times the trunks and bark which is the main feature. |
Tree |
Choisya ternata
Mexican
Orange Blossom
|
Glossy evergreen shrubs that
comes in two main types grown either for wonderfully fragrant white flowers in
summer (and often again in autumn) with green leaves, or for vibrant yellow leaves
in the variety "Sundance" which unfortunately rarely flowers.
"Aztec Pearl" is a flowering green variety with leaves that are more delicately
cut.
The flower scent is
exceptional. To about 6-8ft tall and wide. Best in sun.
|
Shrub |
Cordyline
Cabbage palm
|
These are not fully
hardy, but
with our increasingly frequent and increasingly mild winters, they survive year
round more and more. Don't push it too far in Cambridgeshire, plant them in
sheltered areas away from strong winds and with the protection of a wall if
possible.
|
Shrub |
Cortaderia selloana
Pampas grass
|
It's had a bit of a bad press has
poor old pampas grass with its connotations of 70's housing estates. Like some
other plants though, it's earned its reputation unfairly, largely as a
result of being planted inappropriately.
It is a big plant 6ft tall by about the same wide with flower panicles to
10ft.
Best planted at the margins of a garden or
at the back of a mixed
border unless you have great expanses of lawn.
|
Perennial |
Eucalyptus gunnii
Cider
Gum
|
Actually a tree if left to its
own devices that will go to 50ft + if it's happy. However, don't be too alarmed.
What you do is you treat it as a coppice stool. Let the plant get established
for one or two years and then in Feb / March you cut it down to about 4-6"
above ground level. This encourages it to throw out new shoots from just below
the cut point. The plant will then provide you with lots of very attractive
glaucous blue/green juvenile foliage that can grow up to 6ft from ground level
in a season. It's also reputed to keep midges and mosquitoes at bay, so plant it
near the patio.

Euphorbias
|
E. mellifera, the honey spurge is one of the
larger members of the group and is well placed at the back of the border. It has
vibrant apple-green leaves and the flowers while not being particularly striking, have a probably
unique scent of honey. An excellent addition to any
garden. To 8ft tall and wide. Best in sun tolerates some shade, not fond of
exposure so molly coddle it a bit if you can.
Euphorbia myrsinites Completely different habit to E.
mellifera above. A prostrate creeping plant with blue-green leaves, yellow
"flowers" in spring. 4" tall and spreads to about 18", a
succulent so needs reasonable drainage, goes well with spiky plants or against
gravel / rocks etc.
Euphorbia wulfenii (often
available in one of several named varieties). Bluish green leaves to about
4ft tall. Particularly bright green-yellow "flower" heads in spring.
Well known and deservedly so. Reputed to emit a coffee scent.
|
Perennial |
Fatsia japonica
Castor
oil plant
|
A large plant with large bright
glossy leaves up to 36" long in mature specimens.
Chiefly a foliage plant,
but also produces long lasting white flowers as a bonus which are followed by masses of
black berries. Fits into many different styles of garden, but best in formal or
jungly / tropical types. Grows in sun and also in quite deep shade. To 12ft by
12ft but not for ages.
|
Shrub |
Gunnera manicata
Giant
rhubarb
|
The
leaves are enormous, up to 6ft across borne on prickly stalks to 8ft long. It is
really a bog plant and needs moist conditions, if you think you might be able to
accommodate its requirements and size, then little else will get the same WOW!
effect. To 8ft tall and 10-12ft
across.
|
Perennial |
Hedera canariensis
Canary island ivy
"Gloire
de Marengo"
|
Large shiny variegated leaves
with a jungly feel. Not as hardy as most Ivies you see (which are often as tough
as old boots), so benefits from some shelter. Grow as a climber up a wall or use
as ground cover, pretty vigorous in both situations. To 12ft.

Ilex spp.
Hollies
|
An incredibly useful group,
usually of tough and tolerant plants. Strictly speaking most are trees, though
they grow slowly enough and are easily enough trimmed to be regarded as shrubs
if you want them to be.
Useful
for their evergreen foliage
and winter color provided by berries and / or variegated leaves. Slow growing
and usually only available as smaller specimens as they don't take too kindly to
being moved. Will tolerate shade, especially the darker-leaved forms, variegated
types require sun to bring colors out to the optimum. Hollies are usually
either male or female and only the females have the berries, but they need a
male to achieve this! Ilex aquifolium
"Silver Queen"
- variegated green / cream, male. I. aquifolium
"Mme. Briot" variegated green / yellow, female, red berries. I.
aquifolium " J.C. van tol" - self-fertile female, abundant red
berries, dark green smooth margined leaves. One of my favourites I.
aquifolium "ferox argentea", hedgehog holly - variegated cream /
green, male with spikes all over the surface of the leaf, a bit more fussy about
soil than the others, doesn't like it too heavy or wet. |
Tree
/ shrub |
Juniperus scopulurum
"skyrocket"
|
A
narrowly upright conifer with a blue-grey tinge to the foliage best brought out
when planted in full sun. Use
effectively in pairs either side of a path or entrance, or
use as punctuation marks in planting schemes. |
Tree |
Mahonia spp.
|
Evergreen shrubs with shiny dark
green holly-like leaves and large sprays of highly scented yellow flowers in the
winter months. Make sure you plant it near a path or doorway otherwise you may
never be tempted to venture out and appreciate the scent. M. aquifolium -
Oregon grape is the toughest and will withstand quite deep shade ("Apollo"
is the best variety). Others though are more delicate and less shade tolerant
such as, M. x media "Charity" and M. bealei, plant one of these
if conditions allow.
|
Shrub |
Phormium tenax
New
Zealand Flax
|
Great evergreen fans of sword-shaped leaves
up to 10ft long in green, purple or many variegated varieties. These plants will
grow large! up to 10-12ft across. Flower spikes up to 12ft tall in the "weird
and striking" rather than "pretty" category. The ordinary green one is the
best, and Phormiums actually prefer clay! Best in full sun,
though do tolerate some shade.

Rhus typhina
"laciniata"
Stags Horn Sumarch
|
A striking shrub or small tree
that earns its common name due to the shape of the branches in the winter.
Handsome pinnate leaves up to 18" long that give very good autumn colors.
Tends to sucker quite a lot, but a small price to pay for such a handsome plant,
it also means that you get some extra plants for free to give to friends. To
about 15ft tall and wide.
|
Shrub
/ small tree |
Tamarix
|
Graceful shrub to small tree, wispy frothy pink flowers
produced in summer. Height and spread to 15ft. Withstands a surprising degree of
soil wetness, but don't bother if the planting hole fills with water as you're
digging it.
|
Shrub
/ small tree |
Viburnum tinus
|
Bushy dense evergreen shrub
eventually to about 10ft tall and wide. Fragrant white flowers borne over a long period
through winter and spring, followed by blue/black berries. Tolerates a fair
amount of shade and can be hard pruned. "Eve Price" is a
reliably performing cultivar
|
Shrub |
Vitis coignetiae
Crimson glory vine
|
Large bright green heavily textured leaves up to 12" across whose
autumn colors earn it its common name. A vigorous and large plant that
will grow to 50ft if given space in a mature tree, alternatively grow it up and
over a pergola to give summer shade and autumn fireworks.
