North Star is a new iris from Canadian iris breeder Alan McMurtrie. The petals are creamy white and the centre of the petals have a yellow and blue flash. Cultivate the soil to a depth of 10cms and plant bulbs 6cms deep and 4cms apart. They do not like waterlogged soil, so in heavier soils add grit or humus to help with drainage . Interesting colour combination. We will introduce more of these wonderful selections over the new few years with some even more unusual colours.
