Summary
South Coast Research & Extension Center (South Coast REC/SCREC) is located in Irvine California, this site has a sandy loam soil and plants are irrigated with reclaimed water. UC Davis is located in Davis, California, this site has a silty clay loam soil and plants are irrigated with potable water. More information about the field sites is located in the Nuts & Bolts section.
Aussie Flat Bush™ is a compact, low-growing shrub or tall groundcover with arrow- shaped, bluish grey-green leaves. Plants maintained an informal mounding growth habit in Davis with very healthy foliage, and only a few yellow leaves late in the year. Overall appearance in Davis was very good on all treatments throughout the treatment year earning it our Blue Ribbon™ award for high performance on low water. In Irvine plants showed a few symptoms of yellowing leaf tips, possibly from the reclaimed irrigation water, but nevertheless performed well. Although some plants in Irvine developed a bare center, they typically filled in without pruning as the year progressed. No differences in plant growth or aesthetic quality were observed between treatments at either site. As such, we recommend irrigating Aussie Flat Bush on low water in WUCOLS regions 2 and 3.
