| Botanical Name | Psoralea pinnata |
|---|---|
| Family | Fabaceae |
| Origin | South Africa |
Identification
Sometimes incorrectly called pine weed. Shrub or small tree, to 5 m high. Easily identified when flowering, but looks like a straggly pine tree when not flowering or fruiting. Flowers blue/mauve, pea-like, November - January.Habitats
Shrublands especially dry, slow growing shrublands, coastal areas, tracksides, road verges, dry gullies, and forest margins. Uncommon in Auckland, common Great Barrier Island.Impact to Biota and Ecosystems
May replace manuka causing an impediment to the regeneration of the area. Alters the natural fertility of the soil by fixing nitrogen from its roots. May cause losses to populations of low growing plants with high light requirements. May out-compete natural regeneration after fire. Gumland species or small plants with a limited distribution in dry shrubland or coastal shrubland sites are those species heavily impacted.Dispersal Routes, Vectors, Infestation Sources
Not well known. Perhaps by soil disturbance and water transport or may be carried by birds and mammals. Is still enjoyed as an ornamental shrub in domestic gardens and sold in garden centres. May have been planted in some areas as a roadside stabiliser.Management
