Libertia grandiflora (syn Libertia chilensis) is a striking perennial, bearing slender, upright stems of white flowers above sword-shaped foliage. Its airy habit makes it perfect for growing in a prairie-style display or a gravel garden, particularly among other airy plants.
Grow in well-drained soil in full sun. Remove old foliage to keep it looking its best but allow seedbeds to develop as these are attractive in their own right. Divide congested clumps in spring or autumn.
