The blades are a grey-green colour and are short, usually {{Convert|2|–|15|cm|abbr=on}} long with rough edges.<ref name="bidgeebush">{{cite book |url=https://books.google.com/books?id=6J1VAQAACAAJ|title=Bidgee bush: an identification guide to common native plant species of the south western slopes of New South Wales |last1=Walker |first1=Karen |last2=Burrows|first2= Geoff|last3= McMahon|first3= Lynne |year=2001 |publisher=Greening Australia |location=Yarralumla, Australian Capital Territory |isbn=978-1-875345-61-8 |page=82 |access-date=21 March 2010}}</ref> The erect stems can grow {{convert|1|–|30|cm|abbr=on}} tall. The stems are slightly flattened, often white or green, and occasionally tinged purple in colour.

The seed heads are produced in a cluster of two to six spikes together at the top of the stem, each spike {{convert|2|–|5|cm|abbr=on}} long.<ref name="bidgeebush" />

It has a deep root system; in drought situations with penetrable soil, the root system can grow to over {{convert|2|m|ft}} deep, though most of the root mass is less than {{convert|60|cm|in}} under the surface. The grass creeps along the ground with its stolons, and roots wherever a node touches the ground, forming a dense mat. ''C. dactylon'' reproduces through seeds, [[stolon]]s, and [[rhizome]]s. Growth begins at temperatures above {{convert|15|°C|°F|abbr=on}} with optimum growth between {{convert|24|and|37|C|F}}; in winter or in the dry season, the grass becomes dormant and turns brown. Growth is promoted by full sun and retarded by full shade, e.g., close to tree trunks.{{Citation needed|date=January 2023}}
