Old Man Saltbush

Atriplex nummularia

Old Man Saltbush is a fast-growing shrub commonly used today as a livestock grazing plant. Traditionally, its seeds were used as a food source by the Aboriginal people. The leaves are also edible, salty in flavour and rich in protein, antioxidants and minerals. This species occurs naturally in WA, SA, NT, VIC, NSW and QLD.

Old Man Saltbush leaves may be treated like a leafy vegetable, enjoyed blanched, sautéed, wrapped around meat or fish, used in salads, or for stuffing poultry. Alternatively, they may be dried and used as a herb or sprinkle.

Harvest Saltbush leaves by simply plucking or cutting, taking only as much as you need. The plant may be left to grow, ensuring a year-round supply.

Though Saltbush tolerates drought, salinity and sandy soil in the wild, young plants will struggle to establish in conditions that are too dry and barren. Choose a rich and loamy, but free-draining soil, and water well in the weeks after first planting. Saltbush is suitable for full sun and part shade, but protect from hard frosts. Leaves are grey-green, small (2-3cm) and irregularly shaped, but will grow larger and more vegetable-like in hothouse conditions.

This plant is a woody shrub that can reach up to 3m in height. It may be grown in the ground or kept smaller in pots, if harvested frequently. With regular pruning, it makes a great gap filler or edible hedge.

Why is my Old Man Saltbush growing so slowly?

Old Man Saltbush grows mostly during the warmer season. Plant growth slows noticeably below temperatures of 10°C, but should pick up again in Spring and Summer. To maintain growth rate throughout the year, move your plant into a heated greenhouse or a sunny spot in the home.
