    A few pics of my Japanese irises. Most are grown in pot.

    [​IMG]Iris ensata Blue Beauty web by Erythrone, sur Flickr. Not sure it is the true stuff but it is a very strong grower and easy to bloom (which is not the cas for all JIs....)

    This one is actually an hybrid between Iris ensata and Iris pseudacorus (the yellow marsh European iris).

    Japanese Iris are the most beautiful Iris in the world and
    yours are stunning. They are borderline hardy here (zone 6B) and I'm always afraid to try them because they're
    expensive and I hate losing plants. How do you grow them in pots? I'd love some details.

    Indigo Delight is my favorite, but all are beautiful.

    I was hoping we'd see your garden again this year. Thanks!

    Beautiful! I like them all. I also would be interested in how you grow them in pots.

    I am surprised to read they are borderlin hardy since many JIs are hardy in the ground in our USDA zone 3 gardens. The problem in the garden is not the hardiness but usually the decline of the "fowering power" of the plant after a few years. So we should dig the clumb, divide the plant and not replant in the same spot...But it looks like, in Japan, there is no such issue.... But in North America, most JIs must grow their plants that way.

    Beautiful flowers and photography. Interesting that they are coming into full flower for you now. Here they do their thing in mid June during the monsoon rains.

    Yes, they usually bloom in July here.. some plants even bloom in August. I guess our very long winter make them bloom much later.

    About growing in pots : They are grown outdoors, but with winter protection. I usually put the pots in a child pool during summer, and the plants are grown semi-hydropinic, somewhat like Phrags, but with much more fertiliser. Finding the right fertilizer regime it the main issue for me. They seem to thrive on urea in our summers. Another problem is that they are prone to thrips

    What kind of potting medium do you use? What size pots?
    What a great idea using a small pool. I just happen to have a small pond, but it's in shade. Potting them might
    allow me to grow them in sun and move the pots into
    shade when they're in bloom.

    I usually pot them in a 1 gallon nursery pot, sometimes less for very small plant with a few leaves, sometimes in larger pots, when the clump is very large after some years... I try to use pot taller than wide. I tried many different medium. I now use peat base mix with perlite, with a lot of compost.

    Thank you for the growing tips. I'm definitely going to
    try a couple next summer using Ball Seed growing medium
    which is essentially the same thing you're using. Oh boy!
