The author has attempted in this glossary to compile a set of terms or words commonly used in landscape literature pertaining to general planting design. Landscape architecture is one of the younger professions. It has no distinct vocabulary so recognized by the dictionary of to-day.
Such words as establish, naturalize, open allee, pleached allee, puddle, and leggy as applied to the language of this profession require a definition other than those commonly given to such words. The definitions here given are those which are generally accepted by practicing landscape architects.
No attempt has been made to define a large group of other words which are used in the general field of landscape construction work as differentiated from planting design and its execution.
A plant used to give prominence to its location either because of peculiarly interesting habit of growth, characteristics of fruit or of flowers or foliage.
