In Love with Japanese Irises
What irises need to thrive
Not only are Japanese irises beautiful to look at, but given the right conditions, they do well in the Midwest, says grower John Coble.
Japanese irises take some care, but they're not terribly high-maintenance. They bloom best in full sun, in well-drained soil that's watered well and mulched 2-3 inches deep. They should be divided every three or four years. Most varieties are hardy to Zone 4.
