I've tried to grow Iris cristata, but it doesn't like
something that I do -- it's never lasted very long.
Tom try growing Cristata in pots. I just use mum pots with a good potting soil. Water frequently and add liquid fertilizer every three weeks or so. They put roots down to the bottom of the pot. Six fans planted in a pot right after bloom will fill the pot in two years for me. I have also planted them at the time the new leaves are starting to show. They have done well in 8 hours of sun. Do not let them dry out too much. I have lost some from drying out, never from too much watering.

They do super at my camp ground but not as well in the ground here at home. Check photos on my web page. At my camper the soil is acid. There is also a 2 acre patch of native ones within 1 mile of my camper. I have donated thousands of seeds to SIGNA over the last few years from my patches at my camper.

Linda maybe the pollen is so small it is hard to see. I have never looked. I will this year.

Any one know how Cristata are pollinated? I have never seen a bee or any insect on them. From collecting seed pods I think they are wind pollinated. More pods on the upwind side of the tree, less on the downwind side of the clump. Very few pods on clumps at home which are protected from the wind.
