Commonly known as Big Blue Lily Turf, this perennial forms a clump of dense arching leathery grass-like evergreen foliage. In autumn above the foliage waxy purple flower spikes appear.
A 'go-to' plant for many designers for its versatility in the garden, enhancing both contemporary courtyard and informal cottage planting, it is evergreen and thrives in deep shade.
