Webinar Description:
Primeval plants can be both artistically and educationally enriching elements of landscape design. While
numerous modern relatives of plants that flourished in the dinosaur days are readily incorporated into
landscape or even street plantings, understanding their evolutionary history and past habitats together
can help us generate dynamic plantings resembling ancient environments.
In this presentation, you will
learn about several lineage's of plants that flourished during the dinosaur days, see examples of modern
relatives readily available for landscaping. You will also learn about planting situations suitable for their
display and be provided strategies for learning about past plant communities in your region.
Learning Objectives:
1. Understand the range of primeval plants commonly available for landscape design
2. Understand aspects of evolutionary history and habitats of several key plant groups
3. Understand planting situations suitable for primeval plant display

Jeffrey Benca, Ph.D.
Jeff Benca, Ph.D., is a plant scientist working at the intersection of paleobotany (the study of fossil and ancient plants) and horticulture. He earned his doctorate from the University of California, Berkeley studying how ancient ozone weakening events may have caused global deforestations during Earth’s largest mass extinction. Jeff has authored 6 scientific publications, 1 book chapter, and is a leading expert in cultivating some of the world’s most sensitive primeval plant lineages. He is currently a Research Associate at the Burke Museum of Natural History & Culture and serves as a horticulturist for Amazon’s Horticulture Program in Seattle, WA.
