Coprosma

A genus of about 80 small shrubs and trees that are widespread throughout the country. They show some of the most interesting forms of ornamental shrubs. Dioecious.
Although flowering is usually in the spring months and fruit ripening in Autumn, there is considerable diversity in the range for any species. Out of season flowering may occur. The fruits are a succulent globose drupe  usually crowned with a small remnant of the flowers calyx. The berries of any species can vary greatly in size and colour according to its situation and moisture. Most species are quite simple to raise from seed if the seed is removed from the berry and soaked for 24 hours before sowing. It is suspected that some species may have a germination inhibitor within the berry. Two seeds per berry.
6-8 months time lag between sowing and germination for most species.
Another flush of germination may appear a year later.
