Does anyone on urg grow this iris? I bought it with guidelines to plant
out in a free-draining, moist soil in sun/partial shade. I have since
read that it can be grown as a marginal or in a pot of water. Mine has
doubled in size, but has a couple of concertina'd leaves which suggest
it may be short of water. It is currently grown in full sun in much
improved clay soil. I do water, but sparingly. If you have one, how do
you grow it?

Also, it has not flowered since I bought it and planted it last year.
Googling for flowering times, I get a rather mixed message. Some
articles suggest May/June, others suggest June/July. Comparing it with
other irises I grow, there is no sign of bud build-up within the leafy
growth. Usually I can tell about a month ahead if an iris is going to
bloom.

I would be most grateful for any advice.
