I have to divide mine every second or third year. When the "clump" gets to
be pretty good sized it is time to do it. If you let them go very many
more years than that, mine have quit blooming and died.

I divide mine after they quit blooming. I cut the "clump" in half with a
shovel, dig one of the halves up, cut it into 2 or more pieces again.
Then I replant, give them away, or compost them. If I don't do it this
way mine don't bloom the next year but the second year after
transplanting.

Could you post a picture of your prize. I have two purple and white, but
I wouldn't call them marbled.

Marbled is my word for them, I have no idea if that's the proper term or
not. I posted two pictures in alt.binaries.pictures.gardens under the
subject line "Marbled Iris". I hope that's the right group. If not, let me
know which one you want to access and I'll try to repost them there.

The photos look a little more blue to me than I'd like them to look. They
really are a rich purple, not blue.

Thanks for the dividing info, too.
