It does not appear to be hardy to 20 F soil temperature for any length of time. Encelia farinosa is garden hardy to temperatures in the low 20's and will likely survive brief cold snaps at lower temperatures. When leaf water potentials were compared, they were lower for Encelia farinosa, the species which occurs on sites with less precipitation. It can also be found on hillsides and valleys in Hawaii. It does not appear to be hardy to 20 F soil temperature for any length of time. Encelia farinosa's flower color is yellow. Concerning leaf temperatures of Encelia farinosa and frutescens the author found that: Encelia frutescens.

It has long, oval, silver-gray leaves that are somewhat fuzzy. Both E. californica and E. farinosa attain a maximum rate of photosynthesis between 25 and 30 C, despite the fact that the two species grow in very different thermal habitats.
