Plant Hardiness in Built Environments

Author

Michael A. Arnold

Description

This teaching module addresses the definition of plant hardiness in a landscape design context. Discussion of factors influencing our designation of plant hardiness for landscape taxa centers on the interactions among the genetic potentials and limitations of a given plant genotype, the influence of various factors in the natural and built environment on expression of a plant’s genetic potential, the impacts of cultural practices on plant hardiness in a given landscape, and the relevance of intended purpose in determining hardiness designations for landscape plants. Uses and limitations of the USDA plant hardiness zone maps are also discussed.

Learning goals for the item

The learning objectives for this teaching module are to assist students in being able to formulate and understand the answers to the following questions:

What is plant hardiness?

What factors internal and external to plant taxa influence their hardiness in a given location and for a specific purpose?

What is the usefulness and limitations associated with the USDA plant hardiness zone maps?

What are the important implications of potential interactions among the factors influencing plant hardiness on our selection and incorporation of plants into landscape designs for the built environment?

Appropriate audience

Target audiences for this instructional tool are undergraduate and graduate students in horticulture, landscape architecture, or related plant science areas interested in studying plant materials utilization in built environments.

Review Summary

This is an important teaching module for landscape horticulture and architecture students. The module provides excellent content and use of images addressing plant hardiness in a built landscape design context. It also discusses various environmental and design/management factors influencing plant hardiness, and growth and development of landscape species. The module describes and discusses plant hardiness for landscape taxa centers where the interactions among the genetic potential and limitation of a plant genotype, the influence of natural and built environmental factors, and the practices in cultural and management practices interact to impact the expression of a plant’s genetic potential. The author discusses the uses and limitations of the USDA plant hardiness zone maps.
