Carex limosa, commonly known as bog-sedge or shore sedge, is a perennial herbaceous plant native to peat bogs, acidic fens, and mountain wetlands across North America and northern Eurasia. It thrives in wet, nutrient-poor conditions, often forming extensive colonies. Bog-sedge typically grows up to half a meter tall, with long, threadlike basal leaves that are adapted to the saturated soil of its habitat. The inflorescence is distinctive, with a staminate (male) spikelet at the tip and one or more nodding pistillate (female) spikelets below, which are greenish to brown in color and bloom in late spring to early summer.

Bog-sedge is valued for its role in wetland ecosystems, contributing to the habitat’s biodiversity and functioning. It is not commonly used in conventional gardening due to its specific habitat requirements but can be incorporated into water garden designs or used for wetland restoration projects. Cultivation requires consistently moist to wet soil conditions, acidic pH, and full sun to part shade exposure. While not prone to many diseases, bog-sedge can be outcompeted by more aggressive wetland species if conditions are not ideal. It is not known for being particularly invasive outside its native range.CC BY-SA 4.0
