Sisyrinchium macounii 'Album'

White flowers on clumps of strappy, Iris-like foliage in summer. The flowers are bright yellow-eyed and with delicate green veining. It's a beautiful thing that won't seed itself everywhere and become a nuisance. Prefers full sunshine and a well-drained soil. About 12cm (5") high.

Full name Sisyrinchium idahoense var. macounii 'Album'.
