Arthropodium cirratum, the New Zealand Rock Lily or Renga Renga, is an evergreen clumping perennial with broad, arching grey-green strappy foliage. In spring and early summer it throws up airy sprays of small white star-shaped flowers on slender stems held well above the leaves.
Its real value is dry shade. Most flowering plants sulk under an established canopy or against a south wall, and this one thrives there, forming a dense weed-suppressing carpet in positions where little else performs. It also takes full sun in cooler districts and handles coastal exposure and salt spray.
Foliage sits around 40 to 50 centimetres with flower stems to 70 centimetres, and clumps spread steadily to about a metre. Once established it is genuinely drought tolerant. It is not a plant for heavy frost, so in cold inland districts give it a sheltered position or grow it in a pot that can be moved.
Use it massed under trees, along a shaded boundary, as a soft edge to a path, in a rockery, or in pots on a shaded terrace. It suits coastal, native-adjacent, modern and low-maintenance schemes.
About New Zealand Rock Lily
It is an evergreen clumping perennial native to New Zealand, where it grows on coastal cliffs and rocky slopes. It is known as the New Zealand Rock Lily, Renga Renga, or Rengarenga Lily. It is grown for its broad arching grey-green foliage and its sprays of small white flowers in spring.
Yes, and this is the main reason to plant it. It performs in part to full shade, including dry shade under established trees and against south-facing walls where most flowering plants struggle. In cooler districts it also takes full sun, though foliage holds better colour with some protection from harsh afternoon light.
Foliage reaches roughly 40 to 50 centimetres tall, with flower stems to around 70 centimetres in spring. Clumps spread steadily to about a metre across. It is a groundcover rather than a shrub, so it stays low and fills horizontally.
Spring into early summer. Slender stems carry loose sprays of small white star-shaped flowers well above the foliage, giving several weeks of light, airy display. Trimming spent stems at the base after flowering keeps the clump tidy.
Only lightly. It handles a light frost but foliage is damaged by moderate to heavy frost, so it is not suited to cold inland or tablelands gardens in an exposed position. In those districts plant it under canopy, against a warm wall, or in a pot that can be moved through winter.
Yes. It grows naturally on New Zealand coastal cliffs, so it takes salt spray, wind and sandy free-draining soils without trouble. It is one of the better shade-tolerant choices for a coastal garden.
Space 50 to 70 centimetres apart for a continuous groundcover that closes over in two to three seasons, or a metre apart if you want individual clumps to read separately. Closer spacing suppresses weeds faster.
Water regularly through the first summer while it establishes, then only in extended dry spells. Mulch the root zone and feed with a slow release fertiliser in early spring. Remove spent flower stems and any tired outer leaves. Divide congested clumps in autumn or early spring if they thin in the centre.

Arthropodium cirratum – New Zealand Rock Lily is Native to New Zealand, where it grows on coastal cliffs, rocky slopes and forest margins, largely across the North Island and northern South Island.
The airy spring flower sprays draw bees, hoverflies and other small pollinators, while the dense evergreen clumps provide ground-level shelter for skinks, frogs and beneficial insects in shaded parts of the garden.
Arthropodium cirratum – New Zealand Rock Lily will thrive best in:
Free-draining sandy or loam soils suit it best, reflecting its natural home on coastal cliffs and rocky slopes. It tolerates poorer ground provided drainage is reliable, but will rot in heavy clay or persistently wet positions unless the bed is raised or improved with coarse material and compost.
Is Arthropodium cirratum – New Zealand Rock Lily Drought tolerant?
Water regularly through the first summer while the clump establishes. After that it is genuinely drought tolerant, which is what makes it so useful in dry shade under established trees where root competition takes most of the available moisture.

Trachelospermum jasminoides 'Balls' is Star Jasmine grown and clipped into a dense evergreen sphere. The small glossy leaves sit tight on a woody framework, holding a clean rounded outline year round. White pinwheel flowers open in spring and carry a strong sweet scent right across a courtyard.
Ball specimens hold at about 1 to 1.5 metres tall and wide with light clipping. Full sun to part shade suits them, in any free draining soil. Growth is slow to moderate at 30 to 50 centimetres a year. They handle coastal exposure, light frost and dry spells once the roots are down.
Repeat them along a driveway, either side of an entry, or in pots on a terrace where a formal shape is wanted straight away. They read as structure in a planting scheme without the height of a hedge, and because the form is already trained, a new garden looks settled from the day it goes in.
About Star Jasmine Balls
They are Trachelospermum jasminoides, the common Star Jasmine, grown and clipped into a dense evergreen sphere on a woody framework. Instead of climbing, the plant is trained into a self supporting rounded shape. The foliage is small, glossy and dark green, and the plant carries scented white flowers through spring.
They hold at roughly 1 to 1.5 metres tall and 1 to 1.5 metres wide. Growth is slow to moderate at 30 to 50 centimetres a year, so a light clip once or twice a year keeps the ball tight at whatever size within that range suits the setting.
Full sun to part shade both work. Full sun gives the densest foliage and the heaviest flowering, while part shade produces slightly softer, more open growth and fewer flowers. Avoid deep shade, where the ball thins out and loses its outline. Morning sun with afternoon protection suits hot inland gardens.
Yes, and pots are one of the main uses. A container 50 to 60 centimetres wide with a quality free draining mix will hold a ball for years. Water more often than you would in the ground, especially in summer, and feed in spring and again in late summer. Refresh the mix every few years.
Yes, the foliage is held year round. The glossy dark green leaves take on a bronze tinge in cold weather and green up again in spring, but the plant never goes bare. That is what makes it useful as permanent structure in a scheme, particularly in winter once perennials have died back.
Flowering runs through spring, roughly September to November, and often carries into early summer in warmer districts. The white pinwheel flowers are small but produced in quantity, and the scent is strong on still evenings. Flowering is heaviest on plants in full sun that were not clipped hard just before bud set.
Clip lightly with hedging shears once after flowering and again in late summer if needed, taking only the new growth to keep the outline crisp. Water deeply in dry weather, mulch the base, and feed in early spring. The sap is milky and can irritate skin, so wear gloves when trimming.
Westringia fruticosa, Coastal Rosemary, is an Australian native evergreen shrub from the headlands and dunes of the east coast. It builds a dense rounded bush of fine grey green leaves held in whorls, with small white to pale lilac flowers. Despite the common name it is not the culinary herb.
Mature plants sit at 1.5 to 2 metres tall and 1.5 to 2 metres wide, growing 30 to 60 centimetres a year, and they clip smaller without complaint. Full sun to part shade and sharp drainage are the requirements. Salt wind, sandy soil, drought and light to moderate frost are all handled.
It is a standard on coastal projects, road verges, council garden beds and exposed banks that need erosion cover. Plant 1 to 1.5 metres apart for an informal screen, or 80 centimetres for a clipped hedge. A single plant fills a 40 to 50 centimetre pot on a courtyard or balcony.
About Coastal Rosemary
Westringia fruticosa is an Australian native evergreen shrub from the headlands and dunes of the east coast. It forms a dense rounded bush of fine grey green leaves held in whorls, with small white to pale lilac flowers. Despite the common name it is not culinary rosemary and is not used in cooking.
Mature plants reach 1.5 to 2 metres tall and 1.5 to 2 metres wide. It clips readily to smaller dimensions and is often maintained at around a metre as a hedge or a low mound. Growth is moderate, roughly 30 to 60 centimetres a year, so it holds a trimmed shape well.
It is one of the best shrubs available for exposed coastal work. It grows naturally on sea cliffs and copes with salt laden wind, sand and reflected heat. It is used constantly on beachfront reserves, dune stabilisation projects and seaside gardens where little else holds a tidy shape.
The main flush is spring and summer, roughly September through February, with scattered flowering at other times of the year in mild districts. The flowers are small, white to pale lilac and sit among the foliage rather than above it. Clipped hedges flower less than plants left to grow informally.
Space plants 80 centimetres apart for a tight formal hedge, or 1 to 1.5 metres apart for a dense informal screen. On banks and batters used for erosion cover, 1 metre in a staggered grid gives full ground coverage within about two growing seasons.
Yes. A pot 40 to 50 centimetres wide suits a single plant for a courtyard, entry or balcony. Use a free draining mix, because the roots will not tolerate sitting wet. Container plants need watering more often than those in the ground, plus a light trim to hold their shape.
Trim lightly two or three times a year, taking the soft new growth and avoiding cuts into bare old wood, which reshoots poorly. Water through the first summer, then only in extended dry spells. On most soils it needs no feeding at all, and it resents heavy watering and poor drainage.
Westringia 'Wynyabbie Blue' is a hardy Australian native shrub grown for its lilac blue flowers, which are larger and more freely carried than those of the common white forms. Narrow grey green leaves sit in neat whorls on a dense rounded frame that holds its shape through the year.
Expect 1.5 to 2 metres in height and width at maturity, at 30 to 60 centimetres a year. Full sun brings the heaviest flowering, though part shade is accepted. Drainage matters above everything else, after which it takes salt wind, sandy or gravelly ground, drought and light to moderate frost.
Mass plantings on batters, median strips and coastal frontages are where it earns its keep, and it clips into a low hedge of about a metre without losing its flowering. Plant 1 to 1.5 metres apart for an informal screen. One plant fills a 40 to 50 centimetre pot neatly.
About Wynyabbie Blue Coastal Rosemary
Westringia 'Wynyabbie Blue' is a hardy Australian native shrub grown for its lilac blue flowers, which are larger and more freely carried than those of the common white forms. Narrow grey green leaves sit in neat whorls on a dense rounded frame. It is evergreen and holds its structure all year.
It reaches 1.5 to 2 metres tall and 1.5 to 2 metres wide at maturity, growing 30 to 60 centimetres a year. It clips comfortably to around a metre if you want a lower hedge, and it will hold that height indefinitely given two or three light trims a year.
From spring right through autumn, roughly September to May, with sporadic flowers in winter in mild districts. The lilac blue flowers open in flushes rather than all at once, so there is usually some colour on the plant. Flowering is heaviest in full sun on lean, well drained soil.
Yes. Once the roots are established it needs very little water and copes with extended dry periods, which is why it is used on unirrigated median strips and road verges. Drainage matters more than watering, since the plant will die in soggy ground long before it dies of thirst.
It is. Salt laden wind, sandy soils and reflected heat are all handled, and it is planted routinely on foreshore reserves and beachside gardens. In very exposed frontal positions the plant stays lower and denser than it would inland, which generally suits the situation anyway.
Use 80 centimetres between plants for a clipped formal hedge, or 1 to 1.5 metres for a dense informal screen. For mass planting on banks and median strips, 1 metre in a staggered pattern gives full coverage within about two growing seasons and shades out most weeds.
Trim lightly after each flowering flush, taking soft growth only. Cutting back into bare old wood leaves gaps that will not fill in, so stay on top of it rather than letting it get away. Water through the first summer, then rarely. Avoid rich soils and heavy fertiliser.
