If you can wait until the iris finishes flowering I'll split a bit off for you in the Autumn. It seems to be pretty hardy and it's growing both in the half shade in my garden and in the full sun of my Uncle's.
The yellow flag does behave the same way, but I find that I can 'peel' off older outer leaves and just let them dry for use too.
It's about to bloom, and once it starts to set seed the outer leaves seem to start to wither anyway.
I get an awful lot more leaves from the seileastair than I do from the blue one though. The cordage from the blue one is finer and very, very good, but the yellow is strong, like a soft rope to handle.
cheers,
M
