Indigofera hirsuta

Scientific NameIndigofera hirsuta
CategoriesAnnual or Short-Lived PerrenialNitrogen Fixer
Common Name(s)Hairy Indigo
FamilyFabaceae, Subfamily Faboideae

Description

"Annual or short-lived perennial woody herb to 60 cm; most parts with long, very unequally 2-branched hairs." (PlantNET)

Notes

Indigofera hirsuta is suitable for rehabilitation on many metrics yet it has seen little use to date. We have harvested seed from the plant on both heavy and light soils. On plantings we find that very low sowing rates may produce a strong result. Coupled with the nitrogen fixing properties of the taxon there is the makings of a very useful subject for rehabilitation works where small shrubs and subshrubs are much needed. Seed collectors would benefit by learning to produce the seed on an opportunistic basis. Small, rich pockets of seeding plants may be found and can quickly be harvested by cutting the pod laden branches into bags for drying. The pods can easily be threshed from dry branches, then further broken down in machines before seiving and air-seperating the seed away from chaff.

Historical Notes

Distribution

Widespread around coastal to western Queensland, Northern Territory and northern parts of Western Australia. Also north eastern New South Wales although here it has not been observed further west than Narrabri.
