Planting Instructions for Iris cristata (dwarf crested Iris):

Bloom Time:  Late spring Light:  Part sun to full (dappled) shade
Soil:  Rich, moist, well-draining Moisture:  Average moisture to wet
Planting Depth:  Rhizomes should be lightly covered and lightly mulched Spacing:  12"

Upon arrival:  Unpack box and check that you have everything on your packing list. Iris cristata likes to be slightly dry when shipped, but some moisture in the bag is okay too. Plant everything within a few days.

Soil/Location:  Plant your dwarf crested Iris at the edge of the shady to semi-shady garden in average to rich, moist but well-draining soil. They especially enjoy areas with consistent moisture such as stream side, which is where they will be found in the wild, but they are tolerant of a wide range of conditions so long as they don't get completely dry, otherwise they won't grow or flower well.

Moisture:  Iris cristata doesn't like to dry out too much but are slightly drought tolerant once established. Keep them evenly moist when possible, watering them deeply two or three times a week until they are established.

Spacing: 12" apart

Depth:  Iris cristata spreads from shallow creeping rhizomes. Though they tend to creep right at or slightly above soil level in the wild we find that in the garden they do best with the rhizomes just lightly covered with soil. You can also mulch very lightly after planting to help retain moisture.

General Instructions:  Amend your garden with compost or peat humus to enrich or loosen the soil. Iris cristata grows fine in just about any good, well-draining soil, but by giving them some good compost will help them grow and multiply better. Mix a couple teaspoons of garden food or bone meal into the planting hole and plant at the depth listed above. After planting you can water in once really good and water a couple times a week so they don't dry out too much while they begin to grow. Once growing water deeply two or three times a week, if needed.

Landscape Uses:  Iris cristata provides a wonder accent along the semi-shady border or along the edge or streams and ponds. We find that they do best in the same conditions as other moisture and part shade lovers such as Chelone (turtlehead), Trollius (globeflower), and Monarda (beebalm), however they are so small be sure to plant that where they won't get lost among larger plants.
