Louisiana iris

I don't want to go overboard here! Sisyrinchium palmifolium does grow well
in this area. I have a friend who grows it fine in clay soil , not under
water in summer. A bit weedy for her, especially in wet winter years like we
had. Cannas are, of course, possible although you see them quite a lot
bedded out. I really was looking for less tropical looking plants (no taros,
colocasia etc.) to provide structure year rund with good-looking flowers.
Cypella might work. Very attractive in bloom. Will they sit in water, roots
at water level? Maybe Cypella aquatilis if C. coelstis does not.  

Of course, the Australian Crinum pedunculatum would work. I have a few. It
does get pretty big, however, if it gets down into rich soil. Crinum moorei
is easy, grows here in shade. But at the dege of a pond? Not sure. Or,
Crinum variabile, have some of them. It does grow in streams in the 'wet'
season. With belladonnas in bloom nearby, I suppose that would be a
reasonable choice. No, let's stay practical! Besides, year-round appearance
is not its strength.  

I'll also check other irises, but the news about the water irises in
Louisiana going dormant after bloom is a pity.

Anyhow, some food for thought. Thanks

Hi Andrew, I think the poor summer foliage might depend on the species the
Iris cultivars come from, What about ensatas and the eye shadow Iris?
Asiatic and American as well as African  Crinum species might give you
height at the margins of a pond or even in it. How fantastic to grow some of
the tropical waterlillies. I think some of the bigger Dieramas might do but
they get tatty in the winter, bannas or Cannas? some Moreas are pretty big
and like water also Cypella? and South Americans - Neomarica?? Sisyrinchium
Best of luck
