Cultivation details

Agroforestry Services: Windbreak;  Fodder: Bank;  Management: Coppice;  Management: Fodder;  Regional Crop.

Requires a position in full sun in any well-drained but not too fertile soil[200]. Tolerates saline and very alkaline soils[200]. Succeeds in a hot dry position. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. Plants are usually monoecious but can be dioecious.

Propagation

Seed - sow April/May in a cold frame in a compost of peat and sand. The seed usually germinates in 1 - 3 weeks at 13°c[134]. Pot up the seedlings when still small into individual pots, grow on in a greenhouse for the first winter and plant out in late spring or early summer after the last expected frosts. Cuttings of half-ripe wood, July/August in a frame. Very easy. Pot up as soon as they start to root (about 3 weeks) and plant out in their permanent positions late in the following spring[K]. Cuttings of mature wood of the current season's growth, November/December in a frame. Very easy. Pot up in early spring and plant out in their permanent position in early summer[K].

Link: Elsenburg Detailed info on atriplex nummularia. Known as Oldman Saltbush in South Africa

   Jun 18 2012 12:00AM

Many atriplex varieties, including a. nummularia and a. halimus have significant oxalate content that makes them toxic if eaten raw and in quantity. Cooking in water removes most of this, but when grazed by animals, as it is in some dry areas, the risk of harm is considerable. The statement you've posted for both varieties, that "No member of this genus contains any toxins" is not quite accurate. This study is typical of many looking at saltbush as forage: http://www.jstor.org/stable/4004041
