Iris sibirica ‘Tutu Blue’ is a graceful, elegant perennial prized for its soft sky-blue to lavender-blue blooms that appear in late spring to early summer atop slender, upright stems. The flowers feature delicate standards and falls with gentle colour variation that adds a serene, airy texture to perennial borders, cottage gardens, rain gardens, or moisture-rich beds. Its narrow, grass-like foliage forms tidy clumps that provide evergreen-like structure through much of the growing season. Easy to grow and reliably hardy, ‘Tutu Blue’ thrives in fertile, moist, well-drained soil and performs well in full sun to light shade, attracting pollinators and creating long-lasting colour in mixed plantings.
