Course DescriptionCovers botanical characteristics and field identification of common landscape plants. Emphasizes cultural requirements, pests, diseases, and landscape uses of plants with concentration on evergreen material and plants of winter interest. Audit available.
Addendum to Course Description
Plant material identification skills are basic to all parts of the horticulture/landscape industry. The focus is on evergreen and coniferous trees and shrubs which exhibit winter interest. In this course students are required to identify plant materials by both botanical (scientific) and common names. All of the plants studied are used in landscapes in the Pacific Northwest.
Intended Outcomes for the course
Upon completion of the course students should be able to:
- Identify and discuss evergreen landscape plants in the field based on botanical characteristics.
- Communicate about plant taxa by using Latin binomials and common names.
- Match plants to site conditions based on cultural requirements.
- Organize plants into groupings based on cultural requirements, size and form.
Course Activities and Design
Lecture time will provide the basic botanical information needed to make accurate field identification decisions and will cover the general requirements for growing healthy, useful plants.
Lab time is spent in the field directly observing plant characteristics for identification.
The electronic plant reference requires students to pull information from a variety of sources to organize plants learned in the class, as well as other plants they may be interested in, into a usable guide for plant selection based on site conditions and cultural requirements of the plants.
Outcome Assessment Strategies
Student learning is assessed by:
Plant identification quizzes in the field (3-4 per term)
A written exam at the end of the term that tests
A final plant identification exam in the field
Evaluation of the course project (Electronic Plant Reference)
