Product Details

Yellow Iris

Iris pseudacorus

Yellow Iris brings early-season brightness to the landscape with its bright yellow, upright blooms that rise above vertical green foliage. Blooming in mid to late spring, each flower features soft ruffled petals and classic iris form, adding elegance and contrast to mixed plantings. The foliage remains attractive through summer, forming a fan-like shape that adds structure even after flowering has finished. At maturity, Yellow Iris reaches about 2 feet in height and about 2 feet wide. It grows in tidy clumps and spreads gradually, making it useful for massing or as a vertical accent along borders and pathways.

  • Golden yellow blooms in mid to late spring
  • Upright, sword-like green foliage
  • Grows up to 2 feet tall
  • Clump-forming habit with seasonal interest
  • Performs well in full sun to part shade

Adapted to North Texas conditions, this Iris, also called Yellow Flag, thrives in full sun or part shade, and well-drained soil. To keep its appeal after the flowering season, remove spent flower stalks and trim back foliage in late fall. A strong perennial for North Texas flower beds and naturalistic settings.
