Erect, feathery, short-lived, evergreen perennial shrub <5m tall. Looks like a straggly pine when not flowering. Needle-like leaflets in opposite pairs on soft woody stems. Small clusters of distinctive, large, blue & white pea-like flowers (Nov-Jan) among the leaves. Hairless, wrinkled pods.
Dry, slow-growing shrublands, coastal areas, roadsides, dry gullies, forest margins, rich flats, amongst second growth on rough clay.
Not well known. Seeds possibly dispersed by soil disturbance, water, birds & animals. A garden ornamental.
Alters natural soil fertility by fixing nitrogen. Replaces mänuka & causes losses of low growing plants with high light requirements. Out-competes native vegetation after fire. May be toxic to livestock.
Never use fire as a management tool; implement fire prevention measures. In regenerating bush habitats >4m, allow for natural regeneration, as plant is normally succeeded by tall-growing native spp. Where plant is dense (i.e. no native spp. present), possibly augment with partial & selective control methods to encourage regeneration. Control in low-growing habitats & vector corridors (quarries, roadsides, etc).
1. Pull out small infestations.
2. Spray, spring - summer, (100ml glyphosate+20ml penetrant/10L or 5g metsulfuron+10ml penetrant/10L or 60ml triclopyr +10ml penetrant/10L).
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
