Description
Helictotrichon sempervirens, commonly known as blue feather grass, is a tufted ornamental grass that retains its steel‑blue, narrow leaves throughout winter. It forms compact, half‑spherical clumps and provides a calm, blue contrast among flowering perennials. In summer, delicate yellow‑brown panicles rise above the foliage and sway in the wind. It thrives best in rock gardens, gravel beds, and Mediterranean plantings. The plant is non‑poisonous and safe for gardens with children and pets.
Care instructions
Plant blue feather grass in full sun on a warm site with well‑drained, slightly sandy soil; it does not tolerate wet conditions. Water only during extended dry spells after planting, then it tolerates low moisture well. In early spring (late February to mid‑March, week 9 to 11), trim the clumps hand‑wide and remove dead stems by hand rather than cutting. Divide larger clumps every few years in spring to keep them vigorous and prevent inward thinning. Pair it with varieties such as ‘Pendula’ for a cascading growth at the edge of a pond.
