Scirpus atrovirens - Dark Green Bulrush
We grew and listed this over a decade ago and are glad to have it back in our collection. This is actually a wetland plant but grows in any irrigated area. I remember growing it with Carex muskingumensis and despite the heat of summer, these two green plants added a cooling effect to the landscape.
As a young plant you may think of this as only for the naturalist, but as it matures it enters into the realm of ornamental.
