What a difference one letter in a scientific name can make! I saw this species for the first time in the demonstration garden at North Creek Nursery in Landenberg, Pennsylvania, that mostly grows eastern American native plants, including cultivars of those species many times. I thought the label sign was C. davidii instead that is a Chinese species of David's Sedge. No, it was C. davisii, with the letter "s" not "d." This Davis's Sedge is native to eastern North America from east-central Ontario to New England to Virginia to east Texas then north to Nebraska & North Dakota in open deciduous woodlands in moist upland sites or in floodplains. The species was named after Peter H. Davis of the 20th century. This species is noted as forming loose tufts of fertile and sterile shoots (culms) with alternate leaves. The fertile culms tend to lean sideways at maturity. In fact, it tends to be lanky and floppy at maturity. The foliage goes dormant during the hot summer, though irrigation can help lessen this. Its seed spikelets become an orange-brown and look good. North Creek Nursery does not have this species listed in its catalogue, though they are growing it in their demonstration garden. The specimen I saw there in mid-June had fallen down a good amount.
