Sapphire Blue Oat Grass

Sapphire Blue Oat Grass (Helictotrichon sempervirens) is an ornamental perennial grass known for its striking blue-green foliage. This grass forms dense, neat clumps of slender, arching leaves that can reach up to 2-3 feet in height and width. The color of the leaves is a deep, metallic blue, which adds a unique and eye-catching element to any garden.

In early summer, Sapphire Blue Oat Grass produces tall, erect flower stalks that rise above the foliage, with delicate, oat-like seed heads that start with a soft beige color before maturing to a light golden hue. These seed heads can add visual interest and texture to the landscape, even into the winter months if left untrimmed.

This grass is hardy, drought-tolerant once established, and prefers full sun to partial shade. It thrives in well-drained soil and is ideal for use in rock gardens, borders, or as an accent plant due to its distinct color and form. Its low maintenance requirements and resistance to pests make it a popular choice for gardeners seeking to add a touch of elegance and structure to their outdoor spaces.
