Carex comosa aka Bearded Sedge

Carex comosa is a sedge in the family Cyperaceae. It is a perennial, which means it lives for years. Its common names are bristly sedge and longhair sedge. Its native range spans southern Canada to Mexico. This range takes in the Midwest of the United States. It grows in mild, temperate climates across this broad range. The Royal Horticultural Society accepts its scientific name. It also states that the plant is not native to Britain or Ireland. Kew calls it a perennial or a rhizomatous geophyte. The latter term means it has underground stems.

In gardens, this sedge forms a mound, not a woody frame. Chicago Botanic Garden also lists it as a perennial. The supplied species records give no full-grown height or width. They thus give no firm guide to its final size. Nor do they describe this species' leaves or stems. The RHS gives those details for the whole genus only. They do not show what this species' parts look like. Its mound shape remains the clearest fact about its form.

The flowers are green and bloom from May through June. That puts bloom in late spring and early summer. Chicago Botanic Garden gives both the color and the dates. Its record does not describe the flowers' shape. The supplied sources give no details about the fruit. They do not say what pollinates it or spreads its seeds. The bloom dates come from a garden guide. They do not come from a study of the whole range. They serve as a guide to the bloom season. They do not set dates for each site.

Chicago Botanic Garden lists moist soil for garden use. The plant accepts full sun and partial shade. The same source lists USDA hardiness zones 2 through 9. Garden uses include beds, borders, and ground cover. These uses fit its low mound shape. Yet the records give no height. They state no preferred soil texture or pH. Nor do they give feeding, pruning, or division needs. They list no pest or disease issues for this species. They give no evidence on edible parts or toxicity. These gaps do not prove food value or safety. The Chicago profile is an archived record. The garden no longer updates it.
