Course DescriptionIdentification of summer herbaceous annuals and perennials most commonly used in landscapes. Care, culture, pests, diseases, propagation and landscape use. Audit available.
Addendum to Course Description
Plant material identification skills are basic to all parts of the horticulture/landscape industry. The focus is on summer herbaceous annuals and perennials. 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.
This course can fulfill the requirement for the two-year certificates in Management and Design; and for the two-year Associate Degree in Landscape Technology. It can also be used for a landscape elective. The credits are transferable to the University of Oregon on a petition basis and transfer to Oregon State University.
Intended Outcomes for the course
- In the field, identify, by scientific and common names, a predetermined block of plants.
- Record graphic information from the field and verbal information in a concise, useable fashion for future reference.
- Demonstrate knowledge of plant growth requirements and plant use.
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 required plant notebook requires additional time for obtaining more plant information, graphically documenting plant characteristics and assembly of the information in a useable format. Students use electronic information as well as printed materials.
Outcome Assessment Strategies
Assessment will be based on the student's ability to pass the objectives identified for the quarter. Assessment will take place through plant identification field exams and on the assembly of plant information in the plant notebook. This is a graded course.
