The Acorus gramineus Argenteostriatus is an evergreen ornamental grass. It grows slowly to a size of 50cm after 10 years. The flower colour is white-variegated. This plant is fully hardy.
Sweet flag plants tolerate light shade or full sun, although the plant benefits from afternoon shade in hot climates. However, full sun is best if the soil is extremely boggy. Average soil is fine, but be sure the soil is consistently moist, as sweet flag doesn’t tolerate bone dry soil and may scorch.
