Kutjera (Solanum centrale) is a small, thorny, fast-growing desert shrub of arid central and western Australia, grown for its small yellow fruit that dries like a raisin. The key to growing it is irrigation in hot, dry conditions, since it fruits best after fire or good rains.

About
Solanum centrale, the kutjera, or Australian desert raisin, is a plant native to the more arid parts of Australia. Like other "bush tomatoes", it has been used as a food source by Central Australia and Aboriginal groups for millennia.
Solanum centrale was first described by J.M. Black in 1934.
How to grow it
Traditionally, the dried fruit is collected from the small bushes in late autumn and early winter. In the wild, they fruit for only two months. These days they are grown commercially by Aboriginal communities in the deserts of central Australia. Using irrigation, they have extended the fruiting season to eight months. The fruit are grown by Amata and Mimili communities in the Anangu Pitjantjatjara Yankunytjatjara lands, by the Dinahline community near Ceduna, by the Nepabunna community in the northern Flinders Ranges, and on the Tangglun Piltengi Yunti farm in Murray Bridge, and are marketed by Outback Pride.
