Captivating Flower Color
Deep midnight-purple (almost black), velvety blossoms. Like a streak of lightning on a dark sky, each petal flashes a paper-thin ribbon of yellow. More delicately flowered than Bearded Iris, the chic flowers sway on narrow stems amidst sword-like foliage. In the wild, Iris chrysographes grows in meadows, near streams and on forested hillsides. The Iris Black Form is a stunning addition to any bouquet.

Iris General Information

Iris Sibirica are dazzling flowers that provide a bold splash of color atop narrow stems and sword-like foliage. Prized for their strong upright presentation. Sturdy flower stalks are adorned with intricately patterned flowers in rich colors. Dense root systems prevent weeds as plants grow together in large clumps. Great on banks.

Iris Plant Care

Low care plant - best to leave undisturbed. If transplanted or divided, they may take a couple of seasons to bloom again. Leave a few seed pods on for late season interest. Some self seeding may occur. Foliage develops a golden autumn color which holds into early winter. Cut down old foliage in spring.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
