Louisiana iris

I'll consider it, Peter, now that I have a better idea about what they look
like in summer. I had originally planned on groups along the margin
providing height all year to contrast with waterlilies (hardy and tropical)
and 'surface' genera. There are plenty of taller water species but I had
hoped to include irid members since there are bulbous irid species near the
pond (Watsonias, Crocosomias, Dietes, etc.). Maybe there are some South
African waterplants that could serve the purpose. Watsonia tabularis is
tall, at least  for part of the year,  likes moist ground but is hardly a
water plant.

I think they sometimes dry off during summer in the wild too, -and prefered
water depth depends on the species involved. I only grow fulva and x fulvala
though, but "dural White Butterfly" is a pretty fantastic variety which
would make a good contrast to Black Gamecock.
