Rock iris thrive in nutrient-rich, well-draining, neutral soil, but as the name implies, they will survive even in poor, rocky soils. They naturalize readily if happy where they are planted, and do best in full sun to partial shade. Should be planted 4" deep in fall, and watered in well after planting. Rock Iris are also, very easy to force for winter color! To force these bulbs, plant them about 1" deep in a small, shallow container with lots of grit and a hole for drainage. Water at planting, and then chill the container for about 6-8 weeks (a refrigerator, unheated garage, or basement can work well for this - anywhwere that will be cool, but not freezing. 40 degrees is ideal), before bringing the pot back into the warmth and light.
