The Plant Identification Summer Course teaches the basics of plant identification and identification of each of the plants on the Plant Identification List.

The purpose is to teach plant materials to people who are new to the industry or people with little plant knowledge. The first class introduces students to methods of identification and plant families and the rest of the classes are spent identifying plant material. The NHCLP Plant Identification List covers a wide range of common plant materials used in the landscape industry.

Audience: This course is appropriate for anyone who wants to strengthen their plant material knowledge and is also designed to prepare people for the Identification portion of the NHCLP Exam. It is open to both members of NHLA and non-members.

Dates & Times: Fourteen 3-hour sessions covering the basics of plant identification and identification of each of the plants on the Plant Identification List. Held one evening a week, June – September, at NH nurseries, parks and estates. Watch for 2023 dates.

Locations: Classes will be held at nurseries, parks and estates in NH, central to the majority of participants.  Past classes have been held in the Concord & Seacoast areas. Over 250 woody and herbaceous plants will be reviewed in the course, roughly 18-20 plants per week.  Quizzes will be held weekly to review the identification, common name and scientific name of the plants covered. The plant list is posted posted here.
