Product Description 

Iris ensata ‘Gracieuse’ is a refined and elegant Japanese Water Iris known for its large, flat, orchid‑like blooms. The flowers display white petals edged with soft lavender‑purple, each marked with a delicate yellow signal at the base. Flowering in early to mid‑summer, this variety brings a serene, traditional Japanese aesthetic to pond margins and bog gardens.

This cultivar forms a dense clump of upright, sword‑like foliage, adding structure even when not in bloom. Like all Iris ensata types, ‘Gracieuse’ thrives in moist to wet, acidic soil and is ideal for planting at the pond edge, in bog gardens, or in consistently damp borders. It is fully hardy and performs best in full sun to partial shade.

A standout choice for naturalistic planting, Japanese‑style gardens, and water features, ‘Gracieuse’ offers both architectural foliage and striking summer colour.
