''Calamagrostis'' (reed grass or smallweed) is a genus of flowering plants in the grass family

Poaceae Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns an ...

, with about 260 species that occur mainly in temperate regions of the globe. Towards equatorial latitudes, species of ''Calamagrostis'' generally occur at higher elevations. These tufted perennials usually have hairless narrow

leaves A leaf (plural, : leaves) is any of the principal appendages of a vascular plant plant stem, stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", wh ...

. The

ligule A ligule (from "strap", variant of ''lingula'', from ''lingua'' "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ...

panicle A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are of ...

. Some may be reed-like. The plants may be rhizomatous (underground stems with shoots), stoloniferous (with runners), or caespitose (growing in tufts or clumps). The bisexual spikelets have a single floret and generally they are purple or purple-brown. The spikelets are clustered into inflorescences, which usually develop in early- to mid-summer on long culms ( = stems). Many species of ''Calamagrostis'' are morphologically similar, but they generally occur in distinct habitats, and they have unique geographical distributions. Given the subtle distinctions between many closely related taxa, there are several species complexes that could benefit from additional systematic study. Even the generic boundaries of the genus are controversial. For example, species in the genus '' Deyeuxia'', distributed largely in the southern hemisphere are morphologically very similar to species of ''Calamagrostis''. It may be appropriate to recognize all of these species in a single genus, but this will require detailed scientific study of DNA of species from around the world. Some ''Calamagrostis'' can be very decorative, and are widely cultivated largely in northern temperate zones. The species ''Calamagrostis brachytricha'' and the cultivar ''Calamagrostis'' × ''acutiflora'' 'Karl Foerster' are recipients of the Royal Horticultural Society's

Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit ...

. The word "Calamagrostis" is derived from the Greek word ''kalamos'' (reed) and ''agrostis'' (a kind of grass).
