Accent Plantings:Accent trees generate the showy flower and/or leaf color that provides seasonal interest in the landscape. Likeaccent trees, accent shrubs provide showy flower and/or leaf color. They provide a visual accent when used inmass by themselves or in conjunction with important structural elements such as signs, structure entries, gateways,etc.Ground Covers:Ground Covers consist of two major groups. These groups are plants and non-plants. Ground cover plants, animportant group of plants in the landscape, are usually low growing (6” to 18”) and spreading (3’ to 12’). Theirmost significant function is to cover the ground for weed and erosion control. In addition they can add seasonalinterest with flower and foliage color.Non-Plant Ground Covers:This group consists of several inert materials. They provide the same weed and erosion control functions as plantground covers. However, the inert nature of these materials eliminates the need for irrigation, and usually requiresfar less maintenance than their living counter-parts. This group of ground covers includes but is not limitedto tree bark in a shredded or chipped form, gravels, river run cobbles, chipped fodder from tree pruning operations,and granite fines mixed with cement.Permanent Irrigation:For purposes of these guidelines, any water conveyance system designed and maintained to deliver irrigationwater throughout the expected life cycle of the planting shall be considered a permanent irrigation system.Temporary Irrigation:For the purposes of these guidelines, temporary irrigation systems include water trucks, emitter systems, andtemporary above ground pvc and spray head irrigation systems. The primary Appendixpurpose of the temporary system isto provide an establishment period for the associated planting. After the establishment period is complete (usuallytwo to three years) the temporary system is either removed or abandoned in place.Tree Grove:A grove consists of a substantial (minimum 10) number of trees spaced at a maximum distance of 50% of thetree’s expected height within ten years.
