This isn't your average garden iris—Dinner Plate™ Carrot Cake Japanese Iris is a floral masterpiece made to impress. Its 6-inch, double-layered blossoms are a celebration of cool lavender-blue and crisp white, touched with a golden glow at the heart. Standing tall at about three feet, its upright, sword-like leaves make a striking statement near water features, borders, and damp garden beds.
Unlike the classic tall-bearded iris, this Japanese beauty loves to keep its feet wet. Moist, rich soil or shallow water is its happy place, where it rewards gardeners with lush growth and enormous, velvety blooms. The Dinner Plate™ series is known for oversized flowers and vigorous habits, and 'Carrot Cake' is no exception—a dependable performer that thrives in consistently moist conditions.
Plant it along pond edges, in rain gardens, or anywhere you want bold texture and color. As the last of the irises to bloom, it extends the season with a showstopping finale in early summer. Low maintenance but high impact, this perennial adds elegance, structure, and a touch of whimsy wherever it's planted—proof that sometimes, bigger really is better.

- Born to Be Wet: Unlike bearded irises, this Japanese Iris actually thrives in damp or boggy conditions. It's a dream plant for rain gardens and pondside plantings.

- Last Bloom, Lasting Impression: It's the grand finale of iris season—flowering about a month after Siberian irises, keeping color in your garden longer.
- A Japanese Legacy: Cultivated for centuries in Japanese water gardens, Iris ensata symbolizes purity and elegance in traditional art and culture.
