Calamagrostis (reed grass or smallweed

perennials usually have hairless narrow leaves. The ligules are usually blunt. The inflorescence forms a panicle
. 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

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[5] and the cultivar Calamagrostis × acutiflora 'Karl Foerster'[6] are recipients of the Royal Horticultural Society's Award of Garden Merit.

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