Considered one of the finest white Siberian Irises, Iris sibirica ‘White Swirl’ (Siberian Iris) is a clump-forming perennial that stands out in the late spring to early summer garden. It creates a lavish display of ivory-white, rounded, ruffled flowers adorned with a delicate golden flush at the base of each fall. The elegant blossoms rise atop sturdy flower stalks well above the foliage. After blooming, the grass-like foliage, consisting of sturdy clumps of upright bright-green, narrow, fairly rigid, blade-shaped leaves, is also one of its most attractive garden features. Spectacular when planted in groups.

  • Won several awards, including the Honorable Mention (1957) and the prestigious Morgan Wood Award (1962)
  • Grows up to 24-30 in. tall (60-75 cm) and 18-24 in. wide (45-60 cm).
  • Performs best in full sun or part shade, in moist, fertile, humusy, organically rich, neutral to slightly acidic, well-drained soils. Shade is tolerated, but the flowering performance may be altered. While this lovely iris enjoys a wide range of soils, slightly acidic soil is where this plant will thrive. Drought tolerant, even though this iris prefers adequate moisture.
  • Among the most trouble-free and low-maintenance plants in the garden, Siberian Irises are deer resistant.
  • A welcomed addition to beds and borders, city gardens, coastal gardens, cottage gardens, rain gardens or near streams or ponds, where it provides excellent color contrast.
  • The best time to plant Siberian Irises is spring or late summer.
  • Propagate by division of rhizomes from midsummer to early fall
  • All parts may cause discomfort if ingested. Wear gloves and other protective equipment when handling.
  • Toxic to dogs, toxic to cats, toxic to horses.
  • Iris sibirica is a rhizomatous herbaceous perennial from Europe (including France, Italy, Switzerland, Austria, Czech Republic, Slovakia, Germany, Hungary, Poland, Romania, Bulgaria, Former Yugoslavia, Belarus, Estonia, Latvia, Lithuania, Moldova, Ukraine and northern Turkey) and Central Asia (including Armenia, Azerbaijan and Siberia).
