Summary
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.
The 40% ETo treatment yielded consistently the highest quality ratings, though there were no differences between treatments in relative growth. Since flowering occurred before treatments were applied, it cannot be correlated to irrigation in a 2-year trial.
Shasta and both San Diego County locations gave this species low overall appearance ratings for the year and did not recommend it. As mentioned before, native species can be slow to establish, and given better growing conditions and time, they may have changed their final recommendations.
