Distribution
editThis sedge is native to much of North America, from Alaska across southern Canada and throughout the continental United States, from California to Maine, except for the southeastern region.
Description
editCarex praegracilis grows in wet and seasonally wet environments in a number of habitats, including meadows and wetlands. It tolerates disturbed habitat such as roadsides and thrives in alkaline substrates. Carex praegracilis produces sharply triangular stems up 1 m (3 ft 3 in) tall from a network of thin, coarse rhizomes.
The inflorescence is a dense, somewhat cylindrical array of flower spikes up to 4 or 5 cm (1.6 or 2.0 in) long. The plant is often dioecious, with an individual bearing male or female flowers in its inflorescences, but not both. The range of this sedge is spreading, especially along roadsides where the application of road salt has apparently encouraged its growth.[3][4][5]
