Ensatas or Japanese Iris have the largest flowers to be found in the iris family. A single flower can measure 25cm across. They flower from Mid-June through into late July.  Their foliage is the best in the iris family – with dramatic, tall, scimitar shaped leaves. They like plentiful moisture during the summer and look good by the edge of water and can be planted in the margins of ponds.

After flowering they bear elegant seed heads which persist well into the winter.
Iris ensatas are trouble free plants untroubled by pests and disease. They are deer and rabbit proof and salt tolerant.
