Helictotrichon sedenense is a clump-forming ornamental grass native to alpine meadows of southern Europe and North Africa, thriving best in full sun with well-drained soil. Water every 10-14 days and allow the soil to partially dry between waterings, as it dislikes waterlogged conditions. It makes a striking architectural addition to rock gardens and sunny borders with minimal upkeep required.
