‘Isabelle’ is a captivating Siberian Iris that exudes a delicate charm with its creamy white standards and contrasting bright yellow falls. Bred by the renowned hybridizer Bee Warburton in 1989, this variety has become a favorite among iris enthusiasts for its graceful form and subtle yet striking color combination.
Siberian Irises are known for their slender, elegant stems and delicate flowers, and ‘Isabelle’ is a prime example. Its blooms feature creamy white standards, the upright petals, which provide a lovely backdrop to the falls. The falls, or lower petals, open a vibrant yellow, gradually fading to a paler yellow with intriguing darker yellow veining and a hint of green influence. This creates a captivating interplay of colors, adding depth and interest to the flower.
‘Isabelle’ typically grows to around 28 inches (70 cm) in height, making it taller than the Dwarf Bearded Iris ‘Irish Chant’ and more suited for the mid to back of borders. Its slender stems sway gracefully in the breeze, adding movement and a touch of whimsy to the garden. Siberian Irises are also known for their resilience and ability to thrive in a range of conditions, making ‘Isabelle’ a relatively easy-care and rewarding addition to any garden. With its elegant beauty and subtle color palette, ‘Isabelle’ brings a touch of sophistication and tranquility to the landscape.
