The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.
Terrestrial. Prefers free draining soil (Fromont and King, 1992). Gardens, bushland, wasteland areas and along railway lines. (Ermert and Clapp 1998) Wasteland, scrub in gullies, a garden weed (Webb et al., 1988). Stream banks, riverbeds, coastal and inshore islands, dry shrublands, rocklands, forest steeplands, coastal forest, forest margins and slips, roadside, quarries, wasteland, exotic plantations (Fromont and King, 1992).
Spreading, evergreen shrub 2-5 m high. Stems erect at first then arching, young shoots buff coloured, maturing to dark reddish purple. Leaves up to 70 x 35 mm mostly distributed along young long shoots, often clustered on short shoots. dull and hairless above, pale tomentose below, but becoming hairless. flowers in groups of 15-60, petals white and spreading. Fruit 4-7mm diameter, scarlet or orange-red, glossy.
Similar to C. coriaceus, but the veins are not obvious on the upper surface of the leaf. Also similar to C. pannosus, but this species has smaller leaves with the lower surface persistently tomentose.

Reason For Introduction
Life Cycle Comments
Perennial. Life-span expected to be several decades i.e. may outlive shrubby coprosmas (Fromont and King, 1992). Likely to have seed bank viability of about 2 years (Fromont and King, 1992).
Reproduces by seed.
Each fruit contains many seeds with high viability
Birds eat berries and the contained seeds are dispersed accordingly (Fromont and King, 1992)(Ermert and Clapp 1998).
Tolerant of moderate shade, tolerant of frost, tolerant of grazing (will resprout if cut), wide moisture tolerance (Fromont and King, 1992).
