Know before you buy
These bulbs should be planted in the fall before the ground freezes. This allows them to establish roots during the winter so they are ready to bloom as soon as the soil warms in early spring.
Yes, the Dark Blue Specie Iris is a reliably perennial plant. As long as they are planted in a suitable hardiness zone and given proper drainage, they will return and bloom each spring.
Absolutely. Their compact 4-to-6-inch height makes them an excellent choice for containers, window boxes, or rock gardens where space is limited.
Yes, this variety is considered deer resistant. While no plant is entirely deer-proof, these irises are generally ignored by deer and other common garden pests.
For a dense, professional-looking display, we recommend a planting density of 16 bulbs per square foot. Planting them in clusters or drifts rather than single rows will create the most impact.
They thrive in full sun but will also perform well in partial sun. Ensure they are planted in a location that receives at least a few hours of direct sunlight to encourage the best color and bloom production.
