The reference to Flag iris may be to Iris pseudacorus which is commonly called Yellow Flag iris. It's a beardless iris species that grows well in standing water. It's generally considered a swamp plant, but it's a tough grower and will also grow in regular garden soil. It's considered an invasive plant in some areas, but it will grow alongside the Louisiana iris. There are also many introduced cultivars of the species if you can find a source for them. The old fashioned bearded iris are also called Flags and they wouldn't like wet conditions.
Do the oxblood lilies tolerate wet conditions,
@kittriana Kat? I grow them and they certainly live through drought and heat while in the dormant stage and overnight burst into bloom after a rain in the fall. If the rains come just right, they'll bloom again shortly after the first flush. I've only seen that happen once or twice. A second rain usually doesn't show up quick enough and they won't do it when the leaves have grown out too far. For a day or two they are really spectacular. Photo from a couple of years ago taken in mid-November. They bloomed in October this year.
