Variegata Japanese Iris

• Growth Rate: Moderate growth rate, with plants reaching their mature size in 2-3 years.
• Mature Height: Typically grows 24-36 inches tall.

• Pollinators: Iris ensata 'Variegata' is known to attract bees, butterflies, and other pollinators.

• Wildlife Resistant: This plant is generally resistant to deer and rabbits.

• Blooming Season: Mid to late summer (June to July).
• Leaf Description: The leaves of Iris ensata 'Variegata' are sword-like and prominently variegated with creamy white and green stripes, providing interest even when the plant is not in bloom.
• Flower Description: Large, showy blooms in shades of deep purple-blue with a hint of yellow at the base of the petals. The flowers have a striking fan-like appearance with delicate, ruffled edges.
• Dormancy: This plant dies back in the fall and goes dormant over winter, reemerging in spring.

Cottage gardens – perennial borders – xeriscaping – rock gardens – specimen planting – sunny slopes or well-drained raised beds

– Sword-shaped leaves

– Distinctive variegated foliage: green with vertical white to creamy-yellow stripes

– Erect, fan-like form that provides vertical structure even when not in bloom

– Adds visual interest throughout the growing season

– Two-toned flowers: yellow to cream standards (upright petals), and yellow falls (lower petals) heavily veined with reddish-purple or maroon

– Flowers are bearded, meaning they have a fuzzy “beard” on the falls

– Blooms appear in late spring to early summer

– Usually fragrant and very attractive to pollinators

Deadhead spent blooms to encourage more flowers. Cut back the foliage to the ground in late fall or early winter after the plant goes dormant.

Requires consistently moist soil, especially during the growing season. It is tolerant of wet conditions and can even be planted in shallow water (up to 4 inches deep).

Full sun to partial shade. It prefers full sun for optimal blooming but can tolerate partial shade.

– Not typically harvested for consumption (toxic)

– Flower stems can be cut for use in floral arrangements – harvest when buds are just opening

– Seed pods can be collected in late summer if propagation by seed is desired

– Division of rhizomes is the preferred propagation method and can be done every 3–4 years in late summer to early fall

Fertilize in early spring with a balanced, slow-release fertilizer. A second feeding can be done after the flowering period to encourage strong root growth.

• Winter Care: Mulch in late fall to protect the roots from extreme cold.

• Dividing: Divide the rhizomes every 3-4 years in early spring or after flowering to prevent overcrowding and promote vigorous growth.

• Pest & Disease: Generally disease-free but may be prone to rot if planted in poorly drained soil.

• Pollination: While it can self-pollinate, cross-pollination from insects improves genetic diversity.

– Cross-pollinating – primarily pollinated by bees and other insects

– Insects transfer pollen between flowers for genetic diversity

– Seed set occurs if pollination is successful and conditions are right

– Salvia nemorosa – upright spiky blooms contrast well with iris flowers

– Nepeta (Catmint) – soft, mounding form complements upright irises and attracts pollinators

– Allium – globe-like blooms add architectural interest and bloom after irises

– Coreopsis – provides long-lasting color and thrives in similar dry, sunny sites

– Sedum – drought-tolerant and blends well in rock or xeric gardens

– Peonies – bloom around the same time and add lush structure

– Daylilies (Hemerocallis) – extend bloom season and tolerate same conditions
