Evergreen shrub

camellia-setsugekka

Camellia sasanqua 'Setsugekka'

Evergreen shrub with lax, flowing branches and glossy deep green leaves. Flowers in autumn and early winter with fragrant, pure white, semi-double flowers with prominent yellow stamens and somewhat ruffled edges. Flowers drop before browning.

Can be trained as an espalier or grown as a hedge, standard, or single specimen.

Suitable for a sheltered, semi-shady or sunny position, but avoid hot afternoon sun. If the position is too shady, fewer flowers will be produced. Frost hardy but flowers may be damaged by early frosts. Prefers acidic soil conditions.

 

 

camellia-x-williamsii-anticipation

Camellia x williamsii 'Anticipation'

Evergreen shrub with an upright habit and dark green foliage. Simple, ovate, leathery, glossy, toothed leaves to 9 cm long and 5 cm wide. Large rosy red peony-form flowers, 10 cm across, during late winter.

Les Jury hybrid. Originated in New Zealand as a seedling from a cross between Camellia saluensis and Camellia japonica 'Leviathan'. First flowered in 1959.

Camellia x williamsii 'Anticipation' prefers a sheltered position in partial shade in any well-drained acidic or neutral soil. Tolerates shade and also copes with a position in full sun.

Prune after flowering to maintain shape and compactness.

ceanothus-yankee-point

Ceanothus thyrsiflorus var. griseus 'Yankee Point'

Yankee Point ceanothus, Californian lilac Yankee Point

Vigorous, wide-spreading evergreen shrub, developed from a plant originally collected at Yankee Point in Monterey County in California. Glossy dark green, oval leaves, 2.5-4 cm long, 1.5-3.5 cm wide. Particularly attractive in spring when masses of powdery blue flowers in panicles form a beautiful colour contrast with the young light green leaves and the dark green mature foliage. 

Synonym: Ceanothus griseus var. horizontalis 'Yankee Point'

Prefers a sunny position in well-drained soil, but is also suitable for a partially shaded position. Not happy in wet or heavy soils, but 'Yankee Point' can handle such conditions better than most other Californian lilacs. Drought-tolerant once established. Copes well with poor, sandy soils. Suitable for coastal gardens. Tolerates medium frosts. Prune yearly to maintain compact and vigorous.

Great for covering banks and slopes, especially in coastal areas. Can be trained as a hedge or grown as a container plant.

cestrum-cultum

Cestrum x cultum

purple Cestrum

Evergreen shrub with purple tubular flowers 2-3 cm long in terminal panicles on long, arching branches. Ovate to lance-shaped leaves, 10-15 cm long, to 3 cm wide. Cross between Cestrum elegans and Cestrum parqui. All parts are poisonous. Hardy to -7oC.

Cestrum x cultum may be cut back after flowering to near ground level and will re-grow during the next season to a height of about 2m.

choisya-ternata

Choisya ternata

Mexican orange blossom, Mexican orange

Rounded, evergreen shrub native to southern USA and Mexico. Glossy leaves palmately divided into three leaflets, 5-8 cm long, covered with oilglands, aromatic when crushed.  Clusters of small, star-shaped, scented, pure white flowers, 1-2 cm across, similar to orange blossoms in shape and fragrance. Main flowering season is spring, but flowers intermittently during the rest of the year.

Choisya ternata prefers a sheltered position in full sun, but copes with full shade. In very hot climates a position in partial shade whithout afternoon sun is best. Will grow in a range of soils, including sandy or loamy, and acidic or neutral. Drought tolerant once established. 

Lightly prune after flowering.

 

cistus-brilliancy

Cistus x purpureus 'Brilliancy'

Brilliancy rock rose, pink rock rose

Evergreen shrub, flowering in spring and summer with deep pink, crepe paper like, 5 cm wide flowers with yellow central stamens and a maroon blotch at the base of each petal. Sticky brown  stems and narrow green leaves in opposite pairs. 

Prefers a sunny spot in light, well-draining soil. Tolerates clay. Cistus x purpureus 'Brilliancy' tends to form quite an open shrub, and needs trimming after flowering to keep it compact. No need for fertilisers. Drought-tolerant once established. Suitable for coastal gardens and exposed sites. Frost hardy (zones 7-10). All Cistus species thrive in Mediterranean climate types.

Individual flowers only last one day, but the plant is generally smothered with flowers in particular at the beginning of the flowering season and puts on a fantastic show.

clianthus-maximus

Clianthus maximus

kaka beak, kowhai ngutu-kaka

Evergreen shrub, endemic to New Zealand, but rare in the wild. The pinnately compound, 15-25 cm long leaves resemble those of another New Zealand native plant, the kowhai (Sophora species). Drooping, 8 cm long, red flowers, shaped somewhat like the New Zealand native parrot's (kaka's) beak. May flower at any time during the year, but most  specimens flower during spring or summer. The photo was taken in early spring. Green, pea-like seed pods. 

Clianthus maximus is similar to Clianthus puniceus, and for a long time was treated as a variety of the latter. Also sold as Clianthus 'Kaka King'. Compared to Clianthus puniceus, Clianthus maximus has larger flowers and leaves, and its foliage is glossy and darker green.

Prefers an open sunny position in well-draining, fertile soil. Not tolerant of very wet, waterlogged conditions, but tolerates dry soils once established. When growing conditions are not ideal, Clianthus maximus is susceptible to a range of pests, including caterpillars, slugs, snails, leaf miners and thrips. The shrub tends to have an open habit, in particular when not grown in full fun, so prune regularly to keep the plant compact. Tolerates light to medium frosts. Suitable for coastal gardens and exposed sites. Can be short-lived, and may need to be replaced after 3-5 years. Easy to propagate from cuttings or seed.

Attractive, fast growing, New Zealand native plant with gorgeous flowers in large clusters. Can be trained as a climber or espaliered.

convolvulus-cneorum

Convolvulus cneorum

silverbush, shrubby bindweed, silvery bindweed

Bun-shaped evergreen shrub with silvery appearance, native to the Mediterranean. Silky, grey-green leaves, covered with tiny hairs. White flower buds, flushed with pink, open to short trumpet-shaped, 4 cm wide, white flowers with yellow centers, often completely covering the plant. Flowers close at night and may only partially open on dull days. 

Convolvulus cneorum prefers a position in full sun and light, poor to moderately fertile, well draining soil. Tolerates coastal conditions, drought, and light to medium frosts. Usually free from pests and diseases. Lightly trim after flowering to keep compact. Suitable for containers.

Excellent choice for hot and dry areas. Suitable as a low, informal hedge or path edging. Combines beautifully with purples and blues. The silvery foliage looks great when planted en masse and used as a colour and shape contrast for more architectural shrubs such as dark--leafed flax cultivars, or as a shape contrast for grey, architectural plants like Astelia chathamica 'Silver spear'. 

coprosma-acerosa

Coprosma acerosa

sand coprosma

Low mound-forming, New Zealand native ground-cover with intertwining, brown-orange branches and very small, needle-like, olive green leaves. Blue berries are formed when plants of both sexes are present. Occurs naturally in coastal areas throughout New Zealand.

Prefers a sunny position in well-draining soil.

Excellent ground-covering, low-maintenance plant with an unusual wiry texture that contrasts beautifully with large, shiny, and/or smooth foliage (e.g. flaxes, Astelia, Arthropodium). Great for coastal gardens and hot, dry areas.

coprosma-repens

Coprosma repens

taupata, mirror plant

Variable evergreen shrub or tree to 4-6 m tall, with oblong, thick, very shiny leaves. Leaf size varies from 6-9 cm long and 4-7 cm wide in shade to 2-3 cm long and 1.5-2 cm wide in full sun. Leaf margins may be wavy or somewhat curled under.  Like many coprosma species, the leaves have small pits (domatia) between the midvein and one or more lateral veins of the undersides. Inconspicuous female and male flowers on separate plants. On female plants, flowers are followed by bird-attracting orange-red drupes.

Occurs naturally throughout the North Island and parts of the South Island of New Zealand. Has give rise to a number of variegated cultivars.

Extremely tough plant, tolerant of very exposed coastal situations where it may become prostrate or assume gnarled and twisted shapes. Prefers full sun, but tolerates partial shade well. Copes with deep shade, but is more stretched and less compact. Intolerant of wet or waterlogged soil. Suitable for dry areas. Tolerates light frosts.

Responds well to clipping and is often used as a hedge, in particular in coastal areas.

coprosma-kirkii-variegata

Coprosma x kirkii 'Variegata'

Variegated cultivar of the natural hybrid Coprosma x kirkii, a New Zealand native, ground covering plant. The tiny leaves are green with a cream margin, resulting in a grey overall appearance. Tough, mat-forming, woody plant.

Prefers a sunny or lightly shaded position in any well-draining soil. Drought-tolerant once established. Suitable for coastal or exposed conditions. Good for erosion control on banks. Frost hardy to about -12 deg Celsius. Requires very little attention other than an occasional trim to keep the plant low and dense.

In my city Coprosma x kirkii 'Variegata' is a popular ground covering plant in public spaces, such as gardens of car parks, where it is successfully used to form a dense, tidy looking, light grey mat that helps to keep the weeds down, thus reducing maintenance requirements.

daphne-odora-alba

Daphne odora 'Alba'

Compact evergreen shrub with deep green foliage and highly fragrant white flowers in late winter. Narrow, leathery leaves to 8 cm long. Waxy flowers in clusters of about 4 cm wide.

Prefers slightly-acid soil and a sheltered, partially shaded position with protection from hot afternoon sun. Copes with shade. The soil must be well-draining to prevent rootrot. You could raise the planting bed to improve drainage if necessary. No pruning required other than a light tip prune once a year.

Choose a position where you can enjoy the exquisite perfume, e.g. near the entrance to your house, next to paths, beneath the bathroom window, or grow in a container and move it when in flower to where you like. Great for woodland gardens.

Daphne odora is susceptible to non-treatable virus diseases that may cause yellowing, mottling and distortion of the leaves, so make sure to start with a healthy plant with deep green foliage. Avoid working the soil around the shrub as much as possible; daphnes don't like their roots disturbed. 

dodonaea-viscosa

Dodonaea viscosa

akeake, hopbush, hopseed, hopwood, soapwood, sticky hopbush

Variable, evergreen shrub or small tree, occurring naturally in coastal and lowland forests throughout the North Island, the northern part of the South Island of New Zealand, and the Chatham Islands. Also found in southern Africa, tropical America, the Pacific Islands, and throughout Australia. Alternate, linear to lanceolate, pale to mid-green, sticky leaves, 4-10 cm long and 1-3 cm wide. Tiny creamy yellow, usually unisexual flowers in spring, with male and female flowers borne mostly on separate trees. In summer, female flowers are followed by conspicuous, 1-2 cm wide, winged seed capsules. These capsules are pale yellow, gradually turning reddish brown, starting from the edges of the wings. Attractive red-brown bark, peeling in stringy flakes. Very tough wood, black with white streaks.

Prefers a sunny or semi-shaded position in well-draining soil. Tends to become leggy when light levels are too low. Tolerates light to moderate frosts (zone 9), coastal conditions, dry soils, and strong winds. Does not tolerate wet soils. Prune regularly and lightly to keep compact. Responds to trimming for hedging purposes.

Versatile, fast-growing plant. Dodonaea viscosa can be grown as a specimen tree by gradually removing the lower branches, showing off the bark and developing an interesting, irregular crown, shaped by the wind in exposed situations. Although predominantly used as a foliage plant, a tree laden with seed capsules is a sight to behold. Excellent choice for a hedge, in particular in coastal areas, and when alternated with other hedging plants. Also makes a good filler or backdrop for lower-growing shrubs with different textures and/or foliage colours. 

dodonaea-viscosa-purpurea

Dodonaea viscosa 'Purpurea'

purple akeake

Purple-bronze cultivar of Dodonaea viscosa, originally discovered in the early 1890s on a riverbank in Marlborough in New Zealand. Grows into a small bushy tree or shrub up to 4 m tall and 2 m wide. Narrow-obovate to narrow-elliptic leaves, 4-10 cm long and 1-3 cm wide. The purple leaf colour intensifies during the colder months. Flowers are arranged in terminal panicles to 4 cm long, purplish red, and mostly bisexual. (The species itself produces dull yellow unisexual flowers, usually on separate plants.) Flowers are followed by much larger, winged, purplish red seed capsules in summer. Red-brown, stringy bark. 

Prefers a sunny or partially shaded position in free-draining soil. Suitable for dry, exposed, and coastal sites. Tolerates light to moderate frosts (zone 9). Intolerant of very wet soils. Soft growth responds well to trimming, but avoid pruning old wood. Lower branches can be removed to create a clear-trunk. Leaf colour is better when planted in poor soil.

Makes an interesting specimen tree with attractive bark, beautiful purple foliage, reddish purple seed capsules and, in particular in very windy areas, an irregularly shaped canopy. Excellent choice for hedging purposes in coastal gardens. Cut stems with foliage and seed capsules add an unusual dimension to floral arrangements.

duranta-erecta-geisha-girl

Duranta erecta 'Geisha Girl'

geisha girl pigeon berry

Fast growing, evergreen shrub with glossy green leaves and cascading branches. Purple-blue flowers with wrinkly white edges, mainly during summer, followed by orange-yellow berries. Poisonous leaves and berries. Attracts birds and butterflies.

Duranta repens is a synonym for Duranta erecta. The species itself is native to Southern USA, Central America, the Carribean, and South America, and has become an environmental weed in several warmer parts of the world. The newer cultivars, such as 'Geisha Girl' are thought to be less invasive.

Prefers a sunny position in any well-draining soil. Water regularly until established. Fertilise in spring with an all-purpose fertiliser. Prune after flowering to keep the plant compact. Tolerates light frost (zones 9-12). Can be trained as a standard, grown as a shrub, or trimmed as a hedge.

What a pity this shrub is so toxic! When flowering, it looks absolutely stunning.
