'Variegata'
Iris pseudacorus
Iris pseudacorus, commonly known as yellow flag iris, is a vigorous, moisture-loving perennial with bright yellow flowers that bloom in late spring to early summer. The sword-like, deep green foliage forms dense clumps, making it a striking addition to wetland gardens, pond edges, and stream banks. Thriving in full sun to part shade, this iris tolerates standing water and adapts to a range of soil conditions. While valued for its ornamental appeal, it spreads aggressively through rhizomes and seeds.
