Deciduous plants in New Zealand

Approximately 28 species (4.8%) of the New Zealand woody flora have a marked loss of leaves in winter. Only 11 species are consistently fully winter deciduous (adults are entirely leafless, or nearly so, towards the end of winter) although juvenile plants in some populations may retain significant foliage during the winter. They are:

The following 11 species are best described as semi-deciduous, the degree of leaf loss varying markedly according to exposure, site, and geographic location:

Some populations of Sophora microphylla and Sophora tetraptera are brevideciduous meaning they lose their overwintering leaves in spring at the time of flowering and before the new leaves have flushed, but are otherwise annual evergreens.

Coriaria angustissima, C. plumosa, C. pottsiana, and C. sarmentosa are rhizomatous subshrubs in which the above-ground stem and leaves die back completely in winter. They are rarely included in lists of indigenous deciduous trees and shrubs because they have a herb-like appearance. However, they have woody rootstocks and should be regarded as deciduous shrubs.
