Description
Easily grown in average, medium to wet soils in full sun to part shade. Loves acidic, organically rich, saturated, moisture-retentive soils. During the growing season, it thrives in standing water (up to 6″ deep). However in winter, it is intolerant of both standing water and boggy soils where rhizomes may rot. In order to meet these somewhat unusual seasonal cultural requirements, plants may be grown in pots that are sunk half way in water during the growing season but then removed to dryer ground for fall and winter. Japanese iris grows surprisingly well in garden soils, albeit less vigorously, as long as it receives consistent moisture.
