Native Sedges for the Foundation

Our native Sedges (Carex) function very well as edge plants. Since most of them are less than 12-inches high and fine textured, I prefer to provide a buffer of mulch or hardscape to clearly define them before reaching the lawn. Otherwise, from a distance the lawn appears to be growing right up into the beds and this looks messy. Also, because I create zig-zag planting patterns whenever possible for a more natural look to the overall design, I usually use sedges in clusters of three to six and avoid a solid edge. This enables me to use several cultivars within the same bed.

Sedge cultivars run the gamut in terms of moisture and exposure requirements. Matching existing conditions with individual plant requirements will just about guarantee growing success. My favorites native species are Carex flaccasperma, laxiculmus, and pensylvanica.

Sedges also make great spillers in containers. Speaking of containers... with the spring planting season upon us, next time we'll look at shrubs and perennials suitable for containers. Imagine buying for and planting containers just once and never bothering with them again other than some extra water during summer drought?
