Iris unguicularis ‘Mary Barnard’
One of the toughest of evergreen perennials which gives so much reward for so little effort thriving as it does in almost any position except dense shade. It has thin arching dark green leaves in which the loveliest of fragrant dark blue flowers nestle from May until September. The flowers last well in water if they are gathered in bud just before they unfurl. Sun or light shade. 40cm x 50cm.
