Iris sibirica ‘White Swirl’

Flowers: June-July.  Plant in sun or light shade.  HxS 70x70cm

Siberian flag irises prefer a moist or even boggy soil so are excellent near water, although are tolerant of drier conditions if watered well until established.  This has to be one of the best white varieties, seldom surpassed with newer hybrids.  The white flowers with flaring falls, with a yellow blotch at the centre, are superb.  Best grown in a neutral to acid soil, disliking lime.  Hardiness rating H7. Pot size 1.5 litre.

Care & Maintenance.

Cut back all foliage to the ground in spring.  Plant all iris shallowly with the rhizomes on or just below the surface.  Split every four or five years to maintain vigour.  Propagate by division or seed.  *CAUTION harmful if eaten.
