1. learn some basics of botany, design, culture, and pests and problems as they apply to garden flowers

2. learn to recognize some of the more common (about 200) garden flowers and foliage plants you may see or use in your own landscapes

Whether you are looking to become a green industry professional, or just grow plants at home, this course provides the basics of design, plant care, and plant problems along with a foundation palette of plants.


How it works:

This course has two parts: text notes and plant information.  The 32 lectures are grouped into modules on botany, design, culture, and pests and problems as they relate to flower and foliage garden plants. These include annuals, perennials, and other groups such as aquatic plants, ornamental grasses, roses, even tender tropical "perennials". Tests, plant identification tests, and seven exercises to help reinforce and provide additional information, are taken on-line (on Blackboard, practice tests listed on the course outline are just that--practice only). They are open book, designed to test and reinforce your familiarity with and ability to use the extensive content, and to reinforce key plants, plant features and topics.   Email contact between professor and students is used as needed,for reminders, 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 (

"It is not so very important for a person to learn facts. For that he does not really need a college. He can learn them from books. The value of an education ... is not learning of many facts but the training of the mind to think something that cannot be learned from textbooks."-- Albert Einstein

"The love of gardening is a seed once sown that never dies." -- Gertrude Jekyll
