Seasonality
|
- 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.
|
Ideal For
|
Cottage gardens – perennial borders – xeriscaping – rock gardens – specimen planting – sunny slopes or well-drained raised beds |
Leaf Description
|
– 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 |
Flower Description
|
– 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 |
Planting Instructions
|
- Planting Season: Best planted in spring or early fall.
- Planting Depth: Place the rhizome just below the soil surface with the crown slightly above.
- Soil Requirements: Prefers acidic, well-drained, and consistently moist soil, thriving in boggy areas.
- Spacing: Plant 18-24 inches apart to allow for its spread.
|
Pruning & Maintenance
|
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. |
Water Needs
|
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). |
Light Needs
|
Full sun to partial shade. It prefers full sun for optimal blooming but can tolerate partial shade. |
Harvesting
|
– 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 |
Fertilizing
|
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. |
Additional Care Tips
|
- 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.
|
Pollination
|
– 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 |
Companion Plants
|
– 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 |
