Intended Outcomes for the course

The intended outcome is the development of a scientific basis for the decisions made in designing, management (care and culture), use, and identification of plants in the landscape.

Outcome Assessment Strategies

Evaluation will be based on written assignments from laboratory experiences that deal with scientific observation and data gathering; one project assignment that is either a written report or oral presentation on a specific horticulture topic that relates to botanical principles and practices; two written mid-term exams and a written comprehensive final exam.
