Iris sibirica 'Not Quite White' is a Siberian iris grown for its soft, pale flowers and tidy clump-forming habit. The blooms appear silvery white with faint lavender veining and a greyish-yellow centre.

Each stem carries several flowers, creating a light display from late spring into early summer. The narrow grey-green leaves form upright clumps that add structure to borders even when the plant is not in flower.

This iris suits moist garden soil and works well in borders, rain gardens, and wildlife planting.
