BLACK BAMBOO

Latin name: Phyllostachys nigra

96e1ca355ded53346ebb9e445945bc11_w160

Description: Highly architectural plants giving stature to the garden as well as flowing form. Clump-forming and normally well behaved bamboo with green canes (culms) when juvenile, turning jet-black with age. Although this is currently the most popular bamboo, there are contless others that are well worth trying. P. bambusoides ‘Allgold’ for instancer has bright golden yellow to deep orange canes – an absolute stunner!

Hardiness: Hardy to -15C and lower

Height: 4-8m

Position: Full sun position with plenty of air circulation

Soil: Well-drained garden soil that doesn’t get saturated in the winter

Water: Water to establish, then fairly drought tolerant when mature

Usage: Bamboos are attractive all year, hence should be planted in a dominant position, though their eventual size must be taken into consideration

BULL BAY, SOUTHERN MAGNOLIA

Latin name: Magnolia grandiflora

51d09d5cf2d2940254c70aa9319f57ba_w160

Description: Glorious evergreen shrub and one of the first flowering plants on the planet, making it another plant that was around at the time of the dinosaurs! This impressive magnolia can get rather large, so needs to be positioned well. The oblong, pointed, glossy, dark green leaves are velvety-matt brown on the under sides. The fragrant, large, bowl-shaped flowers (20-30cm across), are absolutely stunning, appearing intermittently from mid-summer to early autumn.

Hardiness: Hardy to -15C and lower

Height: 4-8m

Position: Full sun to dappled shade with protection from wind as the branches break easily

Soil: Any well drained soil with added organic matter

Water: Fairly drought tolerant once established

Usage: Superb as a specimen shrub or tree and also takes well to being trained against a south or west facing wall

CABBAGE PALM, TORQUAY PALM

Latin name: Cordyline australis

2180bf17fded116b6085a0df36c68771_w160

Description: Striking tree that can get many meters high over the years. Best planted as a single trunked specimen, then after a few years its first flowering will cause it to become multi trunked from the top. If cut to the ground it will become multi-trunked from the ground. The greyish-green, strap-like leaves, up to a meter or more long are produced from the trunk tops with bare stems. The enormous flowering trusses are made up of thousands of small highly scented flowers in May. There are several coloured and variegated hybrids available if you want a splash of colour, although they tend to be less hardy.

Hardiness: Hardy to about -10C for short periods. If cut to the ground by severe frost it will re-shoot from the base the following spring.

Height: 1-5m

Position: Full sun to dappled shade away from desiccating winds

Soil: Any well-drained garden soil with added organic matter

Water: Water well to established then mulch well to keep moisture in

Usage: Becomes a very tall plant over the years, so needs a position where all its glory can be appreciated. The trunk becomes fissured and cork-like which is very attractive

CENTURY PLANT

Latin name: Agave Americana

F53baf974adecaffcd409b781766efd2_w160

Description: Only in resent years has it been considered possible to grow spiky desert plants in our temperate gardens, but now with warmer winters very much in mind, many garden centres are now stocking some of these fabulously spiky plants. Agave americana is one of the most dramatically architectural plants available and well worth trying. In this case, size matters – the larger the plant the hardier it is, hence specimens over 90cm tall will have a better chance of survival. Each heavy, thick, leaf gently curves from the base in a shade of matt bluish-grey, edged and with vicious spines – beware these plants bite!

Hardiness: Hardy to about -4C if planted on ludicrously well drained soil. If protected from winter rains, they will take a few more degrees of frost

Height: Up to 1.5

Position: Full sun

Soil: Ludicrously well drained soil with added sand and gravel or grit

Water: Exceedingly drought tolerant – our problem is too much rain!

Usage: For dramatic effect in a sun baked part of the garden. They are also excellent in large containers that can be moved into frost free conditions for the colder months of the year

COMMON TREE FERN, SOFT TREE FERN, WOOLLY TREE FERN

Latin name: Dicksonia antarctica

7bfedc7d9230c2b1837ba0c5ada323c7_w160

Description: The most famous tree fern in Northern Hemisphere cultivation and a truly majestic and architectural plant to boot! The dense, fibrous, dark brown trunk is covered in overlapping frond stalk bases, giving it a rough texture. From the top issue huge mid-green fronds from 1-3m long depending on location. In the spring juvenile fronds emerge unfurling like hairy croziers over several weeks.

Hardiness: Most are capable of taking lows down to about -10C with straw placed in the crown when frost is expected. For light frosts down to -4C no protection is necessary.

Height: 50cm to 5m

Position: Preferably in a shaded wind free location

Soil: Moisture retentive garden soil with added organic mater such as leaf mould

Water: For best growth the trunks of all tree ferns should be kept permanently damp. Also keep the ground around them well mulched as well, thus retaining as much moisture in as possible. Tree fern trunks are difficult to re-moisten once dry – be warned!

Usage: Dramatic pre-historic fern once eaten by dinosaurs. Best planted in groups in the shade of larger trees for best results and of course, drama!

FALSE CASTOR-OIL PLANT, JAPANESE ARALIA

Latin name: Fatsia japonica

Fb2a63b24d33a82350d0d56589a166ee_w160

When the leaves are gently rubbed they give of the odour of burning rubber and peanuts.

Hardiness: Hardy to about -5C for short periods

Height: 1-2m in a

Position: Sheltered sunny location away from prevailing winds or against a south facing wall

JAPANESE ROOT HARDY BANANA, JAPANESE FIBRE BANANA

Latin name: Musa basjoo

227011da1d08f4f1b8e62dfe6ff102e6_w160

This highly architectural banana has a pseudostem (trunk) that can reach up to 2.5m tall and from the top issue arching mid-green leaves up to 2m long and 50cm wide. With age this banana becomes multi-stemmed forming a small banana grove. This is a truly staggering plant and absolutely essential for a truly sub-tropical feel, giving strong architectural value to the garden.

Hardiness: Once established will easily take lows of -3C if protected from desicating winds.

Description: Very tough architectural plants needing little maintenance. It is a vigorous evergreen upright shrub with dark green, spiky foliage on long fairly sparse, deeply fissured and very tactile, cork-like bark covered stems.
