Growing aussie Flat Bush
Position and climate. Full sun to light shade, inland or on the coast, by the company that markets it, which lists it for New South Wales, the ACT, Victoria, inland Queensland away from humid areas, South Australia and Western Australia. The company gives frost tolerance to -5 C; the plant patent calls it tolerant of light frosts and highly salt and drought tolerant, and gives USDA zones 9 to 11.
Soil and water. Most soil types, heavy soils included. The company's care note is to water as required for 8 to 13 weeks until it is established, in a well-mulched bed, with slow-release fertiliser in spring if needed; it is highly drought tolerant and suits low or higher rainfall areas.
Pruning. By the company's account it performs best pruned once a year, or twice a year in gardens for a manicured look; on roadsides it can be pruned less often or not at all.
Flowers. The company's flyer says it rarely flowers, and the plant patent records that flowering was not observed on the plants it describes.
Using aussie Flat Bush
The company that markets it lists roadsides, slopes and commercial and residential landscapes, inland and coastal, for mass planting and as a garden specimen. Its planting density is one to two plants per square metre, which works out at 0.7 to 1 m centres, or one to two plants per linear metre. In gardens the company prunes it twice a year for a manicured look, and on roadsides less often or not at all. The plant patent calls it highly salt tolerant as well as drought tolerant.
What to check before you buy
Aussie Flat Bush is the trade name; the cultivar name on the label is 'SAB01', and growers list it beside the straight species and other selections, so check you are quoting the same plant before comparing prices. The table above shows the sizes growers list; for the roots, pests and hardening off to check, see the HortOS guide to judging nursery plant quality. Stock that crosses a state border moves under the state and territory biosecurity rules on plants and soil.
Prices are set by each grower and shown ex GST. Availability is confirmed by the grower at order.
Common questions
- How big does Aussie Flat Bush grow?
- The company that markets it gives 0.3 to 0.5 m high and 1 m wide. The plant patent, describing four-year-old plants, gives about 0.75 m tall and 1 to 1.2 m wide. The company calls it low growing and compact; the patent calls it mounded and spreading.
- How far apart do you plant Aussie Flat Bush?
- The company's planting density is one to two plants per square metre for a groundcover, which works out at 0.7 to 1 m centres, and one to two plants per linear metre.
- How is Aussie Flat Bush different from ordinary spiny saltbush?
- The company that markets it calls it much lower than the common form. The SA Plant Selector gives the straight species 1 to 2 m high and 1.5 to 4 m wide, and the plant patent gives Aussie Flat Bush about 0.75 m against 1 to 1.25 m for its semi-erect parent line.
- Is Aussie Flat Bush frost and drought tolerant?

- Does Aussie Flat Bush need pruning?
- By the company's account it performs best pruned once a year, or twice a year in a garden for a manicured look. On roadsides it can be pruned less often or not at all, and in natural-style plantings infrequently.
- Where does Aussie Flat Bush come from?
- By its American plant patent, seed of Rhagodia spinescens was raised at a breeding facility in Clarendon, New South Wales, and the one seedling that kept a low, mounding habit was chosen in 2013 and named 'SAB01'. It is sold under Plant Breeders' Rights.
