Spiny Indigo

The Indigofera spinosa, commonly known as the Spiny Indigo, is a low, densely twiggy, spine-tipped shrub of the dry plains of north east Africa and southern Arabia. It carries very small grey-green pinnate leaves and short spikes of small pink to salmon pea flowers held tight against the branches.
It is a low-growing pioneer of hard, overgrazed and gravelly ground, and it holds a compact grey mound without any irrigation at all. It is used in native restoration, low shrub mass and verge planting on arid sites.
The Spiny Indigo is a pioneer for the hardest, most degraded arid ground, where a taller shrub would simply not take.
