Aira praecox is a species of grass known by several common names, including early hair-grass, [1] yellow hairgrass and spike hairgrass. It is native to Europe, where it is found in dry, sandy places, on rocky outcrops, and in heath grassland. [2] It also grows in North America as an introduced species, where it can be found on the east and west coasts in sandy or rocky areas, such as beaches and roadsides. This is a tuft-forming annual grass growing up to about 10 to 15 centimeters in maximum height. [3] : 1073 The thin, narrow leaves are located at the base of the stem, and are typically 0.3–2 millimeters wide. [4] It bears small, tightly congested inflorescences of purple-tinted green bisexual spikelets.
It is an annual, forming low and small but numerous tufts. It flowers from April to June. [2]
Certain moths and butterflies, including the Grayling butterfly and the Coast Dart moth, feed on it as larvae. [5]

Although found all over Europe, the grayling mostly inhabits coastal areas, with inland populations declining significantly in recent years. The grayling lives in dry and warm habitats with easy access to the sun, which helps them with body temperature regulation.
Deschampsia cespitosa, commonly known as tufted hairgrass or tussock grass, is a perennial tufted plant in the grass family Poaceae. Distribution of this species is widespread including the eastern and western coasts of North America, parts of South America, Eurasia and Australia.
