The extended list is for use in places where the soils or geology provide special conditions, and/or where the depth of the planting area (in number of feet from the road) is large enough for planting a reasonable self-sustaining community of plants. Many other native plants, or hardy exotics that fit well in a naturalistic design, are also suitable.
