Drought Tolerant Australian Native Plants For Alkaline Soil

Alkaline soils can be difficult to manage. Most gardening programmes emphasise the use of lime forgetting that many places beyond the east coast of Australia have alkaline soils. This is particularly so in South Australia.

A hint that I was given was to plant in raised beds. As little as 10cm above the surrounding soil will reduce the alkalinity effect. This of course also provides better drainage in heavier soils.
