Poa cuspidata derives its common name from its early flowering period, which begins in March with the very first spring wildflowers. Within its range, other Poa generally bloom later in the spring season.
Description
editPoa cuspidata is a rhizomatous perennial.[4] Its culms are loosely tufted and range from 3–6 dm (12–24 in) in height. Its leaf blades are 2–4 mm (0.079–0.157 in) wide and its leaf sheaths are pubescent, especially at their base. The plant has a loose and nodding panicle, with branches that bear three or four flowered spikelets.[5]
