What are some adaptations of purple needle grass?

Purple needle grass (Stipa pulchra) has several adaptations that enable it to thrive in its native grassland habitats. Its long, fine leaves reduce water loss through transpiration, helping it survive in dry conditions. The grass also has deep root systems that allow it to access moisture and nutrients from deeper soil layers. Additionally, its flowering spikelets are designed for wind dispersal, aiding in reproduction and colonization of suitable areas.
