Libertia grandiflora is an attractive clump-forming evergreen perennial with thin linear foliage and impressive panicles of white flowers. It resembles a Dianella or a miniature Phormium but its flowers are altogether more significant and conspicuous and are held aloft above the foliage on tall scapes, the flowers opening from the bottom to the top like a Sisyrinchium, to which it is related. The flowers are followed by orange-brown seed capsules.

Libertia grandiflora is native to New Zealand and has become increasingly popular in British gardens although it may need some additional protection in colder regions. It does best in a warm sheltered aspect with a rich soil that is both fertile and well-drained. A thick winter mulch of bark is sensible wherever your location.
