About

Carmichaelia juncea, the braided riverbed broom, is a species of New Zealand broom, a prostrate shrub in the family Fabaceae that is endemic to New Zealand. It is extinct over much of its former range, including the North Island.

Where it grows

New Zealand has 23 Carmichaelia species and 14 are listed as threatened or at risk. C. juncea is generally found in rocky areas where there is little competition from other plants; along open river flats, on sandy or stony lake shores and also on exposed rocky outcrops along the coast. Surviving in these tough conditions makes it an excellent plant for rock gardens or for growing in containers. C. juncea was once widespread over both the North and South Island but was probably never very common because of its specific habitat requirements. It is now considered extinct in the North Island while in the South Island it is only found in two areas; Puponga in North-West Nelson and in a few locations in South Westland from Franz Josef to Haast. Like many New Zealand natives the survival of C. juncea is threatened by introduced mammals. At Franz Josef heavy browsing by hares has almost completely prevented seed production in mature plants. It is also under threat from habitat loss; in particular the modification of braided rivers and because of its prostrate habit, introduced weeds.
