Know before you buy
Yes, this is a marginal plant that thrives in shallow water. You can place it in a pond basket or directly into the muddy edges of your water feature, provided the crown is not submerged too deeply.
For the best blooms and strongest growth, this iris requires at least six hours of direct sunlight daily. While it can tolerate partial shade, too little light will result in fewer flowers and weaker stems.
Plant your bare root as soon as possible after it arrives. Keep the roots moist until you are ready to put them in the ground or a container, and ensure the top of the rhizome is just below the soil surface.
The Blue Flag Iris is a native perennial that spreads slowly via rhizomes. While it will naturalize over time, it is generally well-behaved and not considered aggressively invasive in most home garden environments.
Absolutely. The Iris Versicolor is hardy in zones 3-9, meaning it is well-adapted to survive freezing winter temperatures. It will go dormant in the winter and return with new growth in the spring.
