About Fountain grass
Cenchrus setaceus, commonly known as fountain grass, is a perennial ornamental grass forming dense clumps of blue-green foliage. It is distinguished by its soft, arching, feathery inflorescences, ranging from silvery-white to pink, which appear from late summer to autumn, adding an ethereal texture to the garden. It is ideal for borders, rockeries, gravel gardens, and as an accent plant in containers, bringing movement and lightness.

Care tips
It prefers full sun for optimal flowering and tolerates a wide range of soils, though it favors well-drained ones. Once established, it is very drought-tolerant, so watering should be moderate, allowing the soil to dry out between waterings to prevent root rot. In cold climates, it is recommended to protect the roots with mulch in winter and prune it back in early spring before new growth emerges. A common mistake is overwatering, especially in heavy soils, which can be fatal for this species.
