It has a hardiness rating of hardy – average winter (-10 to -5ºc) and is hardy through most of the UK apart from inland valleys, at altitude and central / northerly locations. May suffer foliage damage and stem dieback in harsh winters in cold gardens. Plants in pots are more vulnerable.
When fully mature, Stipa tenuissima can reach an ultimate height of 0.5–1 metres and a spread of 0.1–0.5 metres. For optimal growth, it prefers south–facing or west–facing or east–facing or north–facing aspect and exposed or sheltered positions.
