Know before you buy
While these irises thrive in damp, boggy soil, they do not require a water feature. They perform well in any garden bed as long as the soil remains consistently moist and does not dry out completely.
You can plant 'Royal Robes' in either the fall or the spring. Planting in the fall allows the roots to establish before the spring bloom, while spring planting is ideal for those in colder climates where the ground freezes early.
For optimal growth and air circulation, space your rhizomes 18 inches apart. This provides enough room for the mature foliage to spread to its full 18-inch width.
Yes, this variety is naturally resistant to deer and rodents. While no plant is 100% immune to hungry wildlife, the texture and taste of the Japanese Iris are generally unappealing to them.
These irises prefer full sun to partial sun. For the most vibrant purple blooms, aim for a location that receives at least six hours of direct sunlight daily.
Absolutely. The 'Royal Robes' iris makes an excellent cut flower with a sturdy stem and striking color, adding a sophisticated look to indoor bouquets.
