Iris sibirica ‘Perry’s Blue’ – Graceful Siberian Iris with Rich Blue Flowers
Iris sibirica ‘Perry’s Blue’ is a beautiful hardy perennial, prized for its striking violet-blue flowers and elegant upright habit. Flowering in late spring and early summer, the blooms are carried on slender stems above neat clumps of narrow, grass-like foliage, creating a light and graceful display.
The richly coloured flowers bring vibrant colour to the garden without appearing overpowering, making them ideal for both traditional and contemporary planting schemes. Their refined form and delicate markings add further interest when viewed up close.
The slender green foliage remains attractive long after flowering has finished, providing structure and texture throughout the growing season. Its clump-forming habit makes it particularly effective in mixed borders, prairie-style planting, and waterside gardens.
Thriving in full sun or partial shade, ‘Perry’s Blue’ prefers moist, fertile, well-drained soil and performs especially well near ponds, streams, and damp borders. Hardy and reliable, it gradually forms larger clumps that return with increasing impact each year.
Elegant, dependable, and easy to grow, Iris sibirica ‘Perry’s Blue’ is an excellent choice for adding rich colour and graceful movement to the garden.
