Sophora microphylla seeds grow into the kowhai — New Zealand's most celebrated native flowering tree and the country's unofficial national flower, native to both the North and South Islands. The epithet microphylla means 'small-leaved', distinguishing it from the large-leaved S. tetraptera. A semi-deciduous to deciduous tree or large shrub producing spectacular, drooping clusters of vivid golden-yellow, tubular flowers in late winter to early spring — the kowhai's flowers are the primary nectar source for New Zealand's iconic tui (Prosthemadera novaeseelandiae) and other native honeyeaters, and the bright yellow display signals the arrival of spring across the country. The intricate, interlocking, zig-zag juvenile branching pattern is highly ornamental before the adult foliage develops. Seeds and all parts contain toxic alkaloids and must not be consumed.
