A two-session course in January will expand your skills in identifying deciduous woody landscape plants in the winter landscape. In NH, deciduous woody plants have leaves for only 5-6 months a year, therefore winter identification skills are very important in the landscape industry.
In the first session, winter morphology including fruit, twig and bud features and bark types will be covered in the classroom. ID Keys that can help with identification, both those online and in book form, will be reviewed as well. The second session will be outside reviewing and practicing winter identification of common woody landscape plants. Participants should bring a hand lens and a penknife or leatherman. There will be some provided.
Prospective NHCLPs planning to take the plant identification portion of the exam in March are encouraged to attend.
The course has been approved for 2 NHCLP recertification credits.

This course teaches the basics of plant identification and identification of each of the plants on the NHCLP (New Hampshire Certified Landscape Professional) 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: Thursdays 5:00 – 8:30 pm; June 12 – August 28 (12 weeks); optional review or practice exam on September 4th (to be decided by the class)
Location: Most classes will be held at The Thompson School of Applied Science, UNH, Durham. Some classes will be held at local nurseries and forestry sites.
Cost: $450.00 per student
Instructor: Dana M. Sansom; Associate Professor of Horticultural Technology, Thompson School of Applied Science.
Format: Students will learn the identifying features and landscape value of the plants on the Plant List in the Certification manual. There will be a quiz each week and a final exam. Students will obtain a certificate if they obtain a 60% average.
The Plant ID portion of the NHLA Certification exam is usually held a week or two after the end of this course.

IMPORTANT!! PLANT IDENTIFICATION INFORMATION
The plant identification list has been revised. The new list can be downloaded by clicking here, or from Patty Laughlin. The exam will be taken from the new list.
A knowledgeable person in any phase of the landscape industry must know how to identify plants, their features and landscape value. Plant identification is one of the major parts of the New Hampshire Certified Landscape examination.
The most important skill used in successful plant identification is the ability to observe and define the characteristics of an individual plant including the structure and texture of stems, leaves, flowers and fruit, as well as any available roots. Visual clues as well as the feel and scent of the plant are used.
Knowledge of a plant includes knowing both the common and scientific name. GRIN Taxonomy for Plants (USDA) and the Manual of Woody Plants (M. Dirr.) are the primary references used for the scientific names.
Native status was determined using the USDA Plant Database Native Status. On the plant list, if a plant is native to one state in New England (ME, NH, VT, MA, CT, RI) it is listed as native here.
Certification candidates are asked to identify, from samples and/or pictures, 40 plants selected from the plants in this list. (The number in parenthesis after each heading on the Plant List indicates the number of that type of plant on the plant ID portion of the Certification Exam out of the number of plants in that section.)
Horticopia (a plant database software program) can be purchased from Horticopia.com. There are many different versions but the Horticopia Professional Edition is $140.00 and has most of the plants on the NHCLP list except for weeds. It can also be used to make up plant info sheets for customers. Horticopia.com also has pictures of the plants that you can access for free but there are usually just one picture for each plant.
