The Landscape Institute of Boston Architectural College offers a degree in Landscape Architecture, but for those who are interested, certain courses may be audited at a lower price, without receiving academic credits.  One such course is Drawing the Garden Landscape, taught by Clare Walker Leslie.  This module gives students an opportunity to gain confidence and experience in their drawing skills.  Classes focus on methods for using pencil, pen and ink, colored pencil, and watercolor pencil.  Particular attention will be paid to techniques for drawing individual plant specimens, group assemblages, plants in a landscape composition, perspective, walls, paths, water, buildings, and people in a garden setting.  The goal is to learn how to draw better so that clients (or your loving family) can more clearly understand proposed garden designs.  Emphasis will be on gardens in different seasons and conditions.  Attention will be paid to the specific needs of each student.  Several drawing sessions will be conducted outdoors.  Each student is required to produce and present a final drawing suitable for presentation to a client or inclusion in a portfolio.  The audit fee is $950 (compared to $1,380 if you wish to accrue credits).  Course number VS026.  For more information, log on to www.arboretum.harvard.edu/programs.
