Hello Alberto. My orientalis are semi-dormant and without leaves at this time of year. Much depends on growing conditions. This is a very tough iris which will grow in brackish water up to about 2 inches deep and in periodically wet areas which become bone-dry in the summer. Roots go down about 18 -24 inches They're heavy feeders, but not particular about soil . There is one caveat. They must not be allowed to dry out, This may seem like a contradiction to what I said above where I noted they they can survive in bone-dry condtions, However, when they are growing and are undisturbed, there is almost always enough water in molecular form to sustain the feeding roots which may be two feet down. If, however,one digs this plant and attempts to transplant it, it will die, especially if the infinitesimal feeder roots are cut off or broken. This is why Spuria growers are reluctant to ship if the rhizomes are not going into active growth or cannot be kept moist until being replanted.
