Hundreds of densely-packed slender leaves shoot forth from the crown, making it resemble a firework mid-explosion.

The Leaves reach upward and cascade out from the plant giving it a uniform appearance without collapsing in the middle or losing its shape.

The finely textured leaves of Helictotrichon sempervirens maintain a bright silvery blue through the growing season and each clump maintains a nice fully rounded shape. This makes them a great choice for border plantings in mass, single specimin plants, or strewn among a garden to add texture.

For best results plant Helictotrichon in dry sunny locations to reduce this will result in the most vigorous growth and reduce any chance of crown/root rot. Once established Helictotrichon should only require supplemental watering in drought conditions. Take time in spring to trim back the foliage to a height of 3 or 4 inches before new growth emerges. Divide the plants every 3 to 4 years and they will remain fresh looking for years.
