TUFFY Plants for Arid & Mediterranean Climates: Currently, all Tuffy plant varieties are Australian natives and typically speaking all Australian natives are well adapt to Mediterranean climates: Mild areas of the Pacific Northwest, coastal California, southern California, thermal belt areas of the Central Valley, low desert climates of the Southwest and Western Texas; all great areas for the plants. Of course, some will handle dry conditions better than others and some will be more cold hardy than others so review the plant detail pages for specifics.
As a general rule of thumb: ALL Tuffy plants are evergreen to temps in the mid-twenties, MOST are evergreen to temps in the low twenties and SOME can withstand temps into the mid to high teens. In terms of drought tolerance, new plantings will require regular irrigation until established; once established most of the Tuffy varieties in Arid & Mediterranean climates will require ‘some’ supplemental irrigation during prolonged dry periods. The amount needed to survive will be minimal. However, in these regions, the more irrigation the plants are given the better the foliage will look (i.e. less tip burn). To quantify this: minimal irrigation would be 1-2 times per week for 30 minutes to 1 hour and maximum irrigation would be 3-4 times per week for 30 minutes to 1 hour. These are approximations only meant to serve as a general guideline; actual water requirements will largely depend on your location, climate, site, exposure, and other cultural and environmental factors.
