2. learn some descriptions and cultural specifics for these plants, and where to find this information for future reference,

Whether you are looking to become a green industry professional, or just grow plants at home, this course provides a foundation palette of plants you'll get familiar with, along with information on their use (design) and culture..

How it Works:

This completely online (no text needed, ones can be recommended) course covers specific details and photos on about 200 herbaceous garden plants popular for their flowers, foliage, or both. Extensive descriptions, cultural information, and lists of species and cultivars are given for annuals, perennials, and other groups such as aquatic plants, alpines, ferns, ornamental grasses, roses, even tender tropical "perennials".  Names and information have been updated over the 20+ years this course has been offered.  Quizzes and plant identification quizzes are taken on-line also and at the student's own pace. They are untimed and open book, designed to test and reinforce your familiarity with the extensive content, and to reinforce key plants, plant features and topics.  This course focuses on just the plants from the more extensive (2 credit) Garden Flowers PSS123 online course.   Email contact between professor and students is used as needed, for reminders, to answer questions, and to share information. The syllabus on Blackboard, AND the Getting Started tips, will serve as your contract for the course and should be read thoroughly.  Students are expected to follow the UVM Code of Academic Integrity (

"I do not yet know why plants come out of the land or float in streams, or creep on rocks or roll from the sea. I am entranced by the mystery of them and absorbed by their variety and kinds. Everywhere, they are visible yet everywhere occult." -- Liberty Hyde Bailey, 1858-1954, generally considered the Father of Horticulture

"Bread feeds the body, indeed, but flowers feed also the soul." -- The Koran (central religious text of Islam)
