Frequently Asked Questions

How to care for cut irises?

  • Cut iris stems at an angle early morning when buds are just beginning to open. Place immediately in cool water and recut stems underwater to prevent air bubbles. Change water every 2-3 days and trim stems slightly each time for maximum vase life.

What USDA hardiness zones can Concertina Tall Bearded Iris grow in?

  • Concertina Tall Bearded Iris thrives in USDA hardiness zones 3 through 9. This wide range makes it suitable for most North American climates, from cold northern regions to warmer southern areas. Plant in well-draining soil with full sun for best performance.

What type of soil does Concertina Iris prefer and what pH level?

  • Concertina Iris thrives in well-draining soil with a pH between 6.0-7.5. Like most bearded iris varieties, it prefers slightly alkaline conditions and cannot tolerate waterlogged soil. Plant the rhizome with the top slightly exposed and ensure good drainage for best performance in zones 3-9.

Is Concertina Iris deer resistant?

  • Tall Bearded Irises like Concertina are generally deer resistant due to their bitter taste and tough foliage texture. The sword-shaped leaves and rhizomatous growth pattern make this 27-inch perennial an excellent choice for deer-prone areas in zones 3-9. Shop at Nature Hills for this low-maintenance beauty.

How fast does Concertina Iris grow and when will I see blooms?

  • Concertina Iris grows to 27 inches tall and spreads 12-18 inches wide, blooming first in late spring with a second flush as summer turns to fall. This hardy perennial establishes quickly in zones 3-9. Plant now for blooms next spring season.

How deep should I plant the iris rhizomes and how far apart?

  • Plant iris rhizomes with the top barely covered by soil, about 1/2 inch deep. Space them 12-18 inches apart to match their mature spread. Plant in late summer for best establishment before winter.
