Iris rossii, commonly known as Long-Tail Iris, is an evergreen perennial bulb native to forest margins, grassy slopes, and stream banks in East Asia, particularly in Korea and Japan. This species typically reaches a height of 0.3-0.5 feet and spreads 1-3 feet wide. The Long-Tail Iris is notable for its slender, grass-like foliage and its striking purple flowers that bloom in the spring and summer, adding a splash of color to the garden. The flowers are moderately showy, with each blossom featuring three long, drooping "falls" and three upright "standards," creating a distinctive appearance.

In cultivation, Long-Tail Iris is appreciated for its drought tolerance and suitability for xeriscaping, making it an excellent choice for water-conserving landscapes. It thrives in well-drained, nutrient-rich soils and can be used effectively in rock gardens and alpine scree slopes. While it prefers full sun, it can tolerate part shade, which provides flexibility in garden design. Its low water requirements and ability to adapt to various light conditions make it a low-maintenance option for gardeners. However, it is relatively rare in cultivation outside its native range. Gardeners should be aware that, despite its hardiness, it may be challenging to find in local nurseries.CC BY-SA 4.0
