Carmichaelia nana, syn Carmichaelia enysii or dwarf broom is endemic to the North Island (Central Volcanic Plateau and adjacent ranges) and the South Island (Marlborough, Canterbury, and Otago). It is found in  lowland to alpine areas, inhabiting stable but unconsolidated alluvial river beds and eyots, river terraces, moraines, shingle slopes, lahar mounds and inland volcanogenic dunes. This dwarf, spreading shrub, grows 20-60 mm tall and 0.5 m wide, usually forming a dense mat.  Distinguished from all other dwarf Carmichaelia species by its smaller flowers that are white, flushed with purple that appear from November to February, then seed appears from January to May. An attractive species that deserves wider cultivation. Dislikes humidity.

Veronica (Hebe) elliptica, kokomuka or shore hebe is indigenous to the North, South, Stewart, Solander, Snares, Auckland and Campbell Islands. In the North Island it is scarce, and known only from the west coast in scattered locations on the south Taranaki coast, on Kapiti Island, and Titahi Bay. In the South Island it is found on the north, west, and south coasts, and on the east coast as far north as Oamaru. It is naturalised on Chatham (Rekohu) Island. Indigenous also to the Falkland Islands, it is naturalised near Tierra del Fuego in southern South America, on Maatsuyker Island, Tasmania, and in France. This very hardy, bushy shrub with elliptic leaves grows up to 2m tall+, and is an excellent coastal shrub which grows quite close to the waters edge, does well in most gardens. It has flowers that are white to pale violet, but rarely flowers in northern New Zealand. Hebe elliptica is extremely variable, and some critical selection of the range of wild forms is needed. Plants from near Charleston are particularly distinctive in that they retain their flat, creeping habit in cultivation. Plants from near Titahi Bay, Porirua have been distinguished as Hebe elliptica var. crassifolia for many years, and they differ somewhat by their wider, thicker leaves. Hebe elliptica was discovered by Johann or Georg Forster (father and son), who accompanied Captain James Cook on his second voyage to New Zealand between 1772 and 1774.

Festuca novae-zealandiae or hard tussock is endemic to the North, South and Stewart Islands from the Kaimanawa and Ruahine Ranges southwards. It is found in montane to subalpine regions from sea-level upwards, but mostly above 330m asl to 1200m asl., in tussockland, open shrubland and rock outcrops. It is a fairly common component of low-tussock grassland, particularly in the high country, but is quite often overlooked for garden use. It is an erect, densely tufted, tawny tussock that grows to 50-60cm tall, green to slightly greyish leaves that are rough to touch when stroked downwards, but smooth when stroked upwards. It is a very hardy tussock that will tolerate considerable amounts of drought and exposure, making it useful for very difficult sites. Although it grows well in more favourable sites, it will loose its character if you treat it too well. It flowers from November to December that are followed by seed from January to February.

 Coprosma linariifolia, mikimiki or yellow wood is endemic  to the North and South Islands, from the Hawkes Bay and Manawatu, where it is somewhat local, and is widespread east of the Main Divide in the South Island. It grows from sea-level to 900m asl in lowland to montane forest, scrub, and sometimes shrubland. A very hardy, fast growing tall shrub to small tree up to 6-8m tall, with definite trunk that can have rather smooth to rough fawn-grey bark, with inner bark that is bright yellow to deep orange-yellow in colour. Its flexible branches are slender and dark brown and downy when young, and it has long, narrow, straight, sometimes curved, leathery, dark green glossy leaves that are paler underneath. It prefers open situation, has small flower in November to December followed by translucent white oblong drupes that are often flecked with blue or blue-black, or sometimes wholly black from May.
