We reserve our Blue RibbonTM for plants that maintain high standards of aesthetic quality over the growing season on our lowest irrigation treatment (20% of ETo). Based on our evaluations these plants should perform well on low water in South Coastal landscapes.

  • Plants are listed alphabetically by scientific name
  • Plants were evaluated in full sun or under 50% shade cloth
  • All plants were evaluated in Irvine CA (WUCOLS Region 3)
  • All plants were evaluated using recycled irrigation water
  • The average Overall Appearance rating on Low water during the deficit treatment season is listed as Mean O/A Score (based on a 1-5 scale, where 5 is highest)
