 Elaeocarpus dentatus or hinau is endemic to the North and South Islands, and is found from sea-level to 600m asl., mainly in coastal and lowland forest though occasionally extending into montane forest, from near North Cape to the Catlins River in Otago. Tree up to 20 m tall (usually less), with broad spreading crown.  It is a very handsome medium-sized round-headed tree, 12-13m tall, sometimes up to 20m, with a trunk sometimes 30-90cm through.  This very distinctive tree is easily recognised by the erecto-patent leathery bicoloured leaves, white "lily of the valley" like flowers that appear from October to February, followed by small ovoid purple-black drupes from December to May. It will grow in a sunny or semi-shaded position that has good deep rich, moist soil. The fruits of the hinau were a food source for Maori, but were unpalatable in their fresh state that they needed a considerable amount of preparation after cooking to satisfy with their taste. A coarse meal by made from the prepared kernels, and mixed with water to form a cake that was baked in an umu for up to 2 days. The bark was also used to make a dark blue-black dye.

Pachystegia rufa, or the red-stemmed Marlborough rock daisy is one of three species of Pachystegia, all endemic to New Zealand. There is only a small population of Pachystegia rufa that remains in the wild, that occur in about four valley's in the Haldon Hills, Marlborough. Pachystegia rufa is a species of flowering plants in the daisy family, Asteraceae. It is a dwarf, robust, spreading, evergreen shrub growing to a height of 1 m and to a width of 1m. It has stout branches are covered with brown hairs, with has large, leathery, oblong, dark green, shiny leaves which are smaller than those of Pachystegia insignis. It has shiny, deep green leaves that crowded towards the ends of the branches, that have an under surface that is clad with a thick red-brown, rusty coloured tomentum. In spring it has large white daisy-like flowers with a yellow disc in the centre. When Pachystegia rufa is brought into close association with Pachystegia insignis it readily hybridises creating a variety of hybrids. It is naturally uncommon due to the narrow range in which it grows, but is quite common within its range. Some populations have been damaged by goat and possum browse. In a garden situation it should be grown in a very dry, sunny place in free draining soil, a rock wall is ideal. It dislikes humidity and once established will not tolerate much root disturbance. Transplants with difficulty. An attractive species which should be grown more than it currently is.

Carex virgata is endemic to the North, South, Stewart and Chatham Islands. It is widespread from sea level to about 1000m a.s.l. in open, swampy conditions and also in damp sites within lowland forest. In parts of the country this sedge is often the dominant carice of lowland alluvial forest. A densely clumped, rhizomatous, to tussock-forming sedge, it forms a handsome, distinctive bright green tussock up to 90 – 120cm  tall with a weeping, graceful appearance. Initially it grows directly out of the ground, but older plants can form a trunk from its thickly matted roots. Being a plant that grows in swampy places, it is ideal for growing alongside water or in damp soils.
