Helictotrichon: Growing Guide

Better known as Avena. A hardy perennial belonging to the grass family.


Very beautiful in combination with other perennials and shrubs, including roses. Plant in full sun. Eminently suitable for small gardens, pebble gardens, sunken seating areas etc.


Satisfied with poor, dry soil.


By division or from seed.

Helictotrichon sempervirens syn Avena sempervirens: Height 40-50 cm; the flower stalks grow to 1.5 m. The leaves are grey green to blue green, linear in shape. The flower spikes appear from early summer onwards, they arch gracefully and move in the wind. The bracts of the flowers are straw coloured. Fortunately this ornamental grass has no tendency to be self-sown. In the autumn the clumps turn brown yellow; eventually all surface growth dies down.
