California Penstemons that grow in DRY areas

Yearly rainfall from 10 inches to 40 inches

These Penstemons like 10 to 40 inches of rainfall without added water! They can tolerate a little water to get established. After that leave them alone! They actually like dry summers and generally arid conditions. They do not tolerate garden conditions well. Most do great with sages, buckwheats, and other dry loving plants. These Penstemons are not good for coastal areas or areas with high rainfall or humidity. If this is you go to:
