Said to be somewhat difficult to grow PC iris prefer climates that are wet in winter & dry in summer. Extra well drained soil is needed if summer watering will be frequent. However, extremely dry soil and frozen soils should be avoided too. Not for hot, humid climates
Divided clumps and replant only when new white roots have started to grow. They are located at the base of leaves and should be obvious in late autumn.
