Gorgeous bicolor wine-red and light lavender blossoms are decorated with an intricate white blaze above a yellow signal. None will protest Lady Vanessa in your castle’s garden, methinks!
More delicately flowered than Bearded Iris, Siberians are very adaptable and easy to grow. Equally at home in the flower border, or a moist (even bog) garden.

Iris sibirica 'Lady Vanessa'
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.
An easy to grow, low care plant. Siberian Iris tolerates a wide variety of soils, but will perform best when grown fertile, neutral to slightly acidic, medium moisture, well-drained soils in full sun to part shade. In too much shade, plants tend to produce fewer flowers and foliage tends to flop. Rhizomes should be planted 1-2” below the soil surface and 1-2’ apart. Siberian Iris bloom best after a cold period in winter. A lack of cold period may reduce blooms and the plant's ability to produce new bulbs. Divide the plants about every three years, or once the plants become overcrowded and fewer blooms appear. If transplanted or divided, they may take a couple of seasons to bloom again. Well established plants will tolerate some drought. Leave a few seed pods on for late season interest. Some self-seeding may occur. Cut down old foliage in early spring before new growth emerges.
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!
