This month on We Dig Plants, hosts Alice Marcus Krieg and Carmen Devito visit Zone 8 of the USDA Plant Hardiness Zone Map, which includes the great state of Texas.

First, they're joined by Master Gardener Jenny Peterson of J. Peterson Garden Design, which has been creating cool gardens in the Austin area since 2001. She is also the author of The Cancer Survivor’s Garden Companion: Cultivating Hope, Healing & Joy in the Ground Beneath Your Feet.

After the break, Rick Herman of the Chihuahuan Desert Research Institute tells us about the organization's 507- acre site, which is comprised of semi-desert grasslands and igneous rock outcrops.
