These photos are part of the Marie-Theres Herz Herbarium sheets, donated to the Native Plant Society of Texas. They were all collected and photographed by Marie-Theres Herz from the Dallas Chapter. They are used in our Native Landscaping Certification Program (NLCP) classes and also part of our Native Plant Database.
Marie-Theres Herz was a major contributor to the success of the NLCP. Her love for native plant ecology was evident in the NLCP classroom when she highlighted each species and its place in the plant community. It was evident in her enthusiasm leading students on plant walks to see natives in their natural state. And it was evident in her passionate dedication to developing and sharing this native plant herbarium.
We are honored to share her herbarium images with you here.
