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.

Iris Tropic Night is a variety of Iris sibirica, and they are bog or
marginal irises, so like it moist or even wet. I have several
varieties in my bog garden, in flower ATM, but bear in mind it's very
mild down here and things do tend to flower slightly earlier than
further north. Whether where you have it and the soil it's in is
responsible for it not flowering or having crinkled leaves I don't
know, but it does like damp roots.




Thanks, Chris, that's really helpful! I shall move it temporarily to a
wettish pot until I have an appropriately damp bed prepared. I have a
few bog plants waiting for a home, so that will be an exciting project
for the weekend, weather permitting.
