Iris ensata - Japanese Water Iris
Japanese Water Iris are vibrant, dramatic, and easy to grow. Japan's most beloved iris, they've been cultivated for centuries, resulting in glorious colors and gigantic blooms. They're at home in a pond or boggy location, need abundant water in spring and summer, then go dormant in winter . They're perennial in zones 4-9 and very easy to grow.
Multiple blossoms 6'-12' across grow on tall slender stems. Colors range from vibrant blue and purple to pink and white. These lovely flowers will multiply over time and become a breathtaking sweep.
Seeds should be planted in fall so they can do their natural winter thing (freeze, thaw, freeze, thaw). They'll germinate easily in Spring.
