About Mexican feathergrass
Nassella tenuissima, also known as Mexican Feathergrass or Stipa tenuissima, is a perennial ornamental grass forming dense clumps of fine, silky, light green leaves that sway gracefully in the breeze. Its delicate, golden flower spikes emerge in summer, adding an ethereal touch to the landscape. It's ideal for rock gardens, borders, or as an accent plant in containers, providing texture and movement.
Native range
Southwestern United States, Mexico, and Argentina
Care tips
This grass prefers full sun exposure and tolerates poor, well-drained soils, including sandy or rocky types. It requires moderate watering, being quite drought-tolerant once established; excessive water can be detrimental. Avoid heavy, clayey substrates that retain too much moisture, as this can lead to root rot. A common mistake is planting it in dense shade, which reduces its flowering and vigor.
