Muehlenbeckia complexa, Scrambling Pohuehue, Small-leaved pohuehue, scrub pohuehue, Wire vine, or Maidenhair creeper is a hardy vigorous semi-deciduous New Zealand native vine found naturally on sand dunes and in coastal scrub throughout New Zealand. It is a sprawling coastal creeper/climber that grows into a tangled mass of brown wiry stems with small round leaves and small cream flowers followed later by black seeds held in a fleshy cup. It will form a dense mound up to 2 m wide and it will climb over other plants. It will climb to a height of 5m or more covering trees. In its native environment it plays a key role sealing human and natural disturbances on the forest edge. It also suppresses the growth of introduced weeds, such as blackberry, and promotes increased insect diversity. It used in coastal restoration is an important stabilising sand dune plant and it also providing a valuable habitat for birds (nesting and shelter) as well as providing shelter for insects and lizards. It would make a good trimmed hedge over a wire fence, or as cover over an archway. It has an edible fruit. A few people think it should be class as a noxious weed and banned from sale as in gardens will smother all types of trees. It is now naturalised in Western Australia.

Coprosma wallii is endemic to the North, South and Stewart Islands. In the North Island, rather local and with a predominantly eastern distribution from the Ripia River Headwaters to Wairarapa, with only two western populations at Erua and Paengaroa In in the South Island  it is much more widespread in both the east and west (with new populations still being discovered mainly in the west and south). On Stewart Island, only recently (2000) discovered and still only known from one location. It occupies a range of habitats from seasonally flooded, alluvial forest prone to very cold winters and dry summers, to riparian forest and subalpine scrub, or as a component of grey scrub or mixed Podocarp forest developed on steeply sloping basaltic or andesitic rock. The key feature of the majority of C. wallii habitat is that the substrates are rather fertile and the vegetation is limited by frost, water logging, or severe summer drought. Never associated with broad-leaved canopy trees. A small closely leaved, densely bushy, dark green shrub to small tree of 2-5m tall wit stiff branches and dark green rounded, and fairly thick glossy leaves that are paler underneath. Although quite often not recognised for what it is, it does have distinctive spherical pyrenes (seed) inside its dark blue, sometimes dark red or white fruit; all other Coprosma species have pyrenes that are flattened on one side. Another distinguishing mark is its bright orange inner bark. Coprosma wallii has been in decline, it is not as threatened as once believed, several North and South Island populations are in vulnerable habitats or persist as remnant stands within rough pasture and/or along roadsides. In these sites recruitment is limiting or absent. Weeds remain a long term threat at virtually all known habitats. As a somewhat cryptic plant it is also vulnerable through the failure to recognise it. Some populations on track sides and near popular scenic attractions have been damaged by track maintenance.

Poa cita or silver tussock is endemic to the North, South and Stewart Islands, and is common in lowland to montane areas from sea-level to 1400m asl. It is found on stabilised coastal sands, river-beds, plains and hilly country, and is a conspicuous feature in the drier areas of both main islands, and Stewart Island as well, and is a principal constituent of lowland tussock grassland. This densely tufted tussock has a graceful habit, and grows to about 50cm tall, although more robust forms can reach 90cm. Depending on the form, it can range from light tawny yellow to a tawny colour that is toned down by the number of green leaves per tussock. It is a variable species, and some forms are smaller with finer foliage, while more robust forms have coaser leaves.For best results it is best grown in rather poor and dryish soils in an open sunny position. If treated too well and grown in soils that are constantly moist, it will grow out of character and lose its attractive form. Locally it is the main species of tussock on the Port Hills surrounding Christchurch.

 Samolus repens, maakoako, sea primrose or shore pimpernel is native to native to New Zealand and is found in the Kermadec, North, South, Chatham and Stewart Islands. It is also found in Australia, Norfolk Island, New Caledonia, Easter Island and South America (South Chile), where it is common in temperate and subtropic coastlines. It is commonly found in coastal rock crevices within reach of salt spray, in coastal turf and saltmarsh areas. It is a small creeping or sprawling perennial herb with wiry, dark, slender stems with sometimes ascending or erect shoots. It has small fleshy, spoon-shaped brown-green leaves. It has small white or occasionally pink flowers with a flowering period from November through to March or April, followed by small seed capsules from January to April.

Coprosma rhamnoides or twiggy coprosma is endemic to North, South & Stewart Islands. In Canterbury & Westland it is widespread & abundant. It is found in lowland to lower montane shrubland, scrub and forest, but is less common in higher montane areas. A divaricating shrub with rather stiff but slender branchlets that form a compact plant in exposed habitats. It grows 1 - 2m tall slowly, and has berries only appear on the female plant. The berries can be found on the plant much of the year but especially during March and April, and go from bright red to almost black when ripe.  It is most suited to a dry and exposed site and is hardy to frost.  It is suitable for a low hedge and requires little trimming.
