2025 National Collegiate Landscape Competition - Annual and Perennial Identification List

Aug 25, 2026

2025 National Collegiate Landscape Competition includes an annual and perennial plant identification list used for contest selection and standardized spelling. The instructions require participants to bring two sharpened pencils with erasers and a clipboard, prohibit scratch paper, and ensure phones are turned off and stored. The document defines how the term “selection” applies to all unspecified species, cultivars, and hybrids, specifies lowercase usage, and provides structured plant entries for hardy perennials and annuals/tender perennials in colder climates.
