About this plant
Iris sibirica 'Butter & Sugar' is a striking herbaceous perennial known for its elegant clump-forming habit and vibrant blooms. This Siberian Iris features stunning bi-colored flowers with creamy white standards and buttery yellow falls, adding a splash of color to any garden from late spring to early summer. It thrives in zones 3 to 9, preferring full sun to partial shade and well-drained, moist soils. Hardy to temperatures as low as -40°F, 'Butter & Sugar' is a resilient plant that can reach a mature height of 2 to 3 feet, making it ideal for border planting or naturalizing near waterways. While it is moderately deer resistant, it's also low-maintenance and disease-resistant, making it an excellent addition to any landscape.
