Helictotrichon sempervirens, commonly known as Blue Oat Grass, is a striking evergreen grass admired for its tidy, clump-forming habit and silvery-blue, narrow leaves. The soft arching foliage provides year-round texture and colour, making it a standout in rock gardens, mixed borders, or as an accent in modern planting schemes. In late spring and summer, tall, airy flower spikes rise above the foliage, adding height and movement to the garden. These seed heads mature into a golden tan colour, creating a beautiful contrast against the blue leaves.

Easy to grow and highly drought-tolerant once established, Helictotrichon is a low-maintenance grass that thrives in sunny, well-drained conditions. Its compact size and refined appearance ensure it remains a popular choice for both contemporary and traditional gardens.
