In spite of comments about constant moisture, my small clump has bloomed in spite of neglect at the street-side edge of a clay-heavy bed.

I'm sure it would be happier with more water and organic matter, and I hope to improve conditions for it next year.

I grew this Iris fulva from seed several years ago. You have to have patience. I used a large needle to prick a hole in the coat of each small seed. Then I put the seed in a ziploc bag in damp peat moss and placed it in the refrigeratoar until the seed sprouted. Takes several months for them to sprout but is worth the wait.

I have this in my little pond. The pond never freezes over completely, and I don't remove the plant from the pond in winter. It seems perfectly content with my benign neglect.

I believe this is the red iris that grew along the Bayou Teche behind my Grandparent's cypress cabin in South Louisiana when I was a young child. My Grandfather had several small wooden boats, called "pirogues," tied up to a short wooden dock, and I loved to play down on this dock, where you could get up close to these flowers. From a distance, in the sun, they were a blaze of red against the dark waters of the bayou. These red irises were growing along the bank of the Bayou in the partial shade of low hanging branches of live oaks, dripping in Spanish moss.

The excellent book "The Louisiana Iris, The Taming of a Native American Wildflower," second edition, published by The Society for Louisiana Irises, goes into great detail about the original five species of Louisiana... read more

This is one of the parent species of the 'Louisiana Iris'. It hybridizes freely with I. giganticaerulea, I. brevicaulis, and I. x nelsonii. Wild populations were nearly wiped out due to the demand by European iris breeders because of the ease of crossing and its red color.

Native to marshes, bogs and swamps, this iris adapts readily to garden environments and has proven itself to grow well outside of its native range.

The foliage begins growing in the fall and usually dies back in the summer.

Flowers attract hummers and bees. They are usually brick colored, but can be anywhere in the red/yellow part of the spectrum and bicolored flowers are not uncommon.

Seems a bit more shade tolerant than the other irises in its group.
