The 2018 Farwest Show, August 22–24 in Portland, Oregon, has scheduled Lorence R. Oki, a specialist in water-related issues in horticulture, to speak on the descriptive differences between “low water use” plants and “drought tolerant” plants.
Oki, a cooperative extension specialist with the plant sciences department at the University of California Davis, will deliver his address, “Low Water Use or Drought Tolerant Landscape Plants: Are They the Same?,” Friday, Aug. 24, 9:45–10:45 a.m., Room B110. The terms “low water use” and “drought tolerant” are used to describe plants and their irrigation needs, but the terms are not synonymous. Oki will discuss the differences and plant characteristics that indicate how plants use water. He’ll briefly discuss the California landscape water conservation regulations and field trials used to assess landscape plant water use. The resulting information is used to assist with compliance and inform plant professionals how the tested plants may perform when exposed to deficit irrigation.
At UC Davis, Lorence studies water related issues in both production and landscape horticulture including biological water treatment systems, nursery hydrology, water management, nitrogen management, plant salinity tolerance, landscape plant water use, and residential runoff. He is a third-generation nursery person and was a greenhouse and nursery grower before coming to the university.
