Carex schweinitzii, common name Schweinitz's sedge, is a Carex species native to North America. It is a perennial. [1]
Carex schweinitzii is a sedge with long, slender rhizomes that range from 0.2–0.65 m (7.9 in–2 ft 1.6 in) in height. Its ligules are wider than long. Its peduncles are short, and its male spikelets are solitary while its female spikelets are spreading and erect. [2]
Carex schweinitzii occurs most often in calcium-rich soils near water, such as in springheads, springy seeps, and wet ground along cold spring-fed streams. More rarely the plant occurs in mixed or coniferous cover and even in the open. [3] The plant is mostly local but is abundant where it is found. [4]
It is listed as endangered in Connecticut, [5] Massachusetts, North Carolina, Pennsylvania, and Wisconsin. It is listed as threatened in New York and historical in Rhode Island. [6]

Muhlenbergia capillaris, commonly known as the hairawn muhly, is a perennial sedge-like plant that grows to be about 30–90 cm (0.98–2.95 ft) tall and 60–90 cm (2.0–3.0 ft) wide. The plant includes a double layer; green, leaf-like structures surround the understory, and purple-pink flowers outgrow them from the bottom up. The plant is a warm-season grass, meaning that leaves begin growth in the summer. During the summer, the leaves stay green, but they morph during the fall to produce a more copper color. The seasonal changes also include the flowers, as they grow out during the fall and stay healthy till the end of autumn. The muhly grows along the border of roads and on plain prairies. The grass clumps into herds, causing bush-like establishments in the area the hairawn muhly inhabits. The flowers are very feathery and add a cloudlike appearance to the top of the grass. It is native to eastern North America and can be used for a multitude of purposes, including ornamental gardening and farming. It was voted 2012 plant of the year by the Garden Club of America.
