Too many choices!
Just finished a preliminary plant list for a new residential project high in the Oakland hills, and can't quite believe the list is just short of 500 different species! While this garden is very large for a local project,(one acre front garden and 3.5 acres total), there is no way I'll end up being able to fit even half that many varieties into the final design.
My frustration is that it seems like such a large space ought to handle more varieties, but at least one third the space will be hardscape and/or lawn, reducing current turf areas by 50% or more. There is just so many plants that are stunning in August/September here, and just driving around town each day I can add another dozen to the list.
The main problem with garden design/planting design here locally is that there can be such an overwhelming selection of plants to choose from
