Helictotrichon sempervirens Description
Helictotrichon sempervirens has wonderful, steel blue foliage color for an ornamental grass that remains attractive throughout the season. Drought proof once established, it thrives in humidity and well drained soil in a sunny spot in your garden.
Bright fine-textured, semi-evergreen steel blue blades growing up to 2' tall & 3' across. In summer, delicate arching wheat-colored inflorescence reaching 2' above the clump gracefully arch outward.
Helictotrichon is most striking when used as a ground cover, or edging, and looks beautiful when combined with other drought tolerant sun perennials such as Coneflowers, and Sedums.
Very little maintenance is required with the exception of trimming back foliage in late winter.

Ideas and How-to's
Recommended for You:
Soil: Easily grown in average, dry to medium, well-drained soil. Best blue color occurs in dryish soils.
Light: Full sun -- too much shade and the plant flops over and opens up in the middle.
Water: Needs regular watering until established. Once established will tolerate drought, but benefits from supplemental summer watering in hot, arid climates.
Spacing: 2.00 to 2.50 feet
Fertilizing: Most ornamental grasses are not heavy feeders, so little is needed. Once established, can feed with light application of time release fertilizer in spring.
Winterizing: Is evergreen in warmer growing zones. In cold regions the foliage sometimes needs to be tidied up with scissors in spring, but quickly regrows. It can be cut back to a few inches in height in late winter if needed.
Maintenance & Pruning: Remove withered leaves as they appear. Clumps may be easily divided in spring.
