Yarai (‘Night Thunder’) Iris is a cross between Iris pseudacorus (‘Yellow Flag Iris’) and Iris ensata (Japanese Iris). This cross comes from Japanese Iris breeder Hiroshi Shimizu, and the species name indicates both parents. ‘Yarai’ means ‘Night Thunder,’ paying tribute to the unusual color combination of peach, yellow and dark purple veining. Iris pseudata ‘Yarai’ performs beautifully in wet sites, even standing water. The unusual flowers are borne above the green sword-like foliage in late May and June.
Easily grown in average, medium to wet soil in full sun to part shade. An adaptable plant which tolerates a wide range of soils. It is best grown in very moist, fertile, slightly acid soil, including boggy conditions, but will also tolerate a poor, dry soil because its thick roots penetrate the soil deeply.
