Yes, 'Pinstripe' is hardy in USDA zones 4 through 9. It is a resilient perennial that can withstand cold winters, provided the roots do not dry out completely.

No, this is a marginal plant, not a fully submerged aquatic plant. It prefers to have its roots in consistently moist or wet soil at the edge of a pond rather than being completely underwater.

At maturity, the Iris Ensata 'Pinstripe' reaches a height of 2 to 4 feet and a spread of 1.5 to 2 feet. You should space multiple plants at least 2 feet apart to allow for proper airflow and growth.

While it is adaptable to part shade, the plant performs best and produces the most vibrant blooms when given access to full sun. If your pond area is heavily shaded, you may see fewer flowers during the early to mid-summer season.
