September 12, 2023 Abbeville, La.


The Louisiana Iris Conservation Initiative (LICI) has a Louisiana iris restoration project underway with their partners, the Friends of the Palmetto Island State Park, in the boardwalk swamp at Palmetto Island State Park near Abbeville, La. Part of the 2023 plan for the long-term project is to plant 600 I. nelsonii species of the Louisiana iris in the boardwalk swamp this fall. (The I. nelsonii irises is known locally as the Abbeville Red iris.) One critical job that needed to be accomplished was to remove the Chinese Tallow invasive tree species from the boardwalk swamp where the irises would be planted.

This August 2023 photo was taken from the Palmetto Island State Park boardwalk of the swamp where the irises will be planted this fall. All of the trees that are 30' tall or

smaller seen in the photo are the invasive Chinese Tallow tree.


The Chinese tallow is a drought-tolerant tree native to China and Japan. It was first introduced in South Carolina during the 1700s as an ornamental tree and then for making soap from seed oils. It was planted from eastern North Carolina southward to Florida. From Florida, it spread westerly through Louisiana and Arkansas into Texas.

Photo: Chinese tallow trees can be identified by broad, waxy-green leaves, often with an extended tip or “tail.” New growth briefly appears reddish.


In the early 1900's, it was used as an ornamental tree in Louisiana because most of Louisiana's native trees do not produce fall-colored leaves. The Chinese tallow tree does.

Photo: The Chinese tallow tree can be easily spotted in Louisiana forests when its leaves change color in late fall. Once this happens, the green color starts to fade from the leaves, and then reds, oranges, and yellows become visible. The leaves from most of Louisiana's

native hardwood trees turn brown in color.


The south/central part of Louisiana, where the Palmetto Island State Park is located, is part of Louisiana's Acadiana region, also known as cajun country. The Chinese Tallow tree is known as the Chicken tree in the region.


The Chicken trees needed to be removed from the park's boardwalk swamp before the two iris plantings planned for later this year. This was because the Chicken trees would compete with the irises, just as they were competing with the native Bald Cypress in the boardwalk swamp for moisture and nutrients in the soil. Also, trying to remove the Chicken trees after the irises were planted would risk volunteers trampling the irises. LICI and the park manager decided to set September 9th as the day to remove the Chicken trees.

He told the history of the Abbeville Red iris and its discovery. He also spoke about why the display of these irises at the park's boardwalk is so important to so many people, literally from around the world, as a place to see this rare species of Louisiana iris when they bloom.

The September 9th event was co-hosted by Palmetto Island State Park and the Louisiana Iris Conservation Initiative (LICI), with the Friends of Palmetto Island State Park, Inc. sponsoring the event by supplying snacks, drinks, and sandwiches. In the days leading up to September 9th, it became a community-wide event with volunteers signing up from a Scout Troop in Lafayette, Abbeville Rotary Club, Abbeville Garden Club, Vermilion ARCH 4-H club - including some of the parents, Friends of Palmetto Island State Park, Inc., volunteers from people staying at the park, and LICI's volunteers. Approximately 50 volunteers showed up for the event.


The swamp was dry due to the extreme drought the area has been experiencing, which made it easier for the volunteers to get around to do the work.

The park manager, Andrea Jones, was very supportive of the effort. She found many of the volunteers, allowed her staff to help deliver, set up, and take down everything needed for the event at the boardwalk base station, and allowed the group to use the nearby meeting room building and its porch.

Small red flags were set next to each Chicken tree so the volunteers would not need to determine which trees in the swamp needed to be cut down. Then, volunteers with either tree limb loopers or a chainsaw would cut the trees down. The cut trees were hauled to the swamp's edge and left to rot among the palmettos. A select few volunteers would then squirt each tree stump with a herbicide to kill the roots. They would collect each red flag as they were finished. Most trees ranged in size from twenty feet tall or less with a 1" to 1 1/2" diameter trunk.

As a way to add a festive feeling to the event, a local aspiring singer/songwriter Brody Lemaire, along with his singer and percussionist sister, Zoey Lemaire, offered to donate their time to come out and play for the other volunteers as they worked. "Their playing and singing were a wonderful background for the groups working out in the swamp," Gary Salathe, president of the Louisiana Iris Conservation Initiative, said afterward.

At the end of the event, Salathe said, "I have no idea how many Chicken trees were pulled up or cut down, but it was a lot! When the Abbeville Red irises we will be planting this winter bloom throughout the swamp at the boardwalk next spring, everyone will have a clear view of the show, thanks to the work of the volunteers today."

The Louisiana Iris Conservation Initiative (LICI) has a Louisiana iris restoration project underway with their partners, the Friends of the Palmetto Island State Park, at the boardwalk in Palmetto Island State Park near Abbeville, La. One of the project's goals is to increase the number of I. nelsonii species of the Louisiana iris growing in the swamp at the boardwalk for the public to see them bloom and learn about this threatened native iris species. (The common name for the iris is the Abbeville Red iris.) Another goal is that at some point in the future after the blooming irises are verified as I. nelsonii irises, they could be thinned out to be returned to the nearby Abbeville Swamp. Since this swamp is the only place in the world where this Louisiana iris grows naturally, any I. nelsonii iris plant originated from there or has parentage from an iris collected from the swamp in the past.

A small group of LICI volunteers was invited by one of the landowners of the Abbeville Swamp to visit it during the iris bloom in early April 2023. Although the group was excited by the irises they found, they were disappointed to find huge areas of the swamp where no irises were growing. The exact reason is unknown, but it is known that the irises in this swamp have been aggressively removed by iris collectors since their discovery in the late 1930s, up until the late 1990s, sometimes without the landowners' permission.


In June of 2023, Louisiana iris enthusiast, iris grower, and LICI volunteer Kent Benton donated hundreds of I. nelsonii iris seedlings for the Palmetto Island State Park iris restoration project. They are currently growing at LICI's New Orleans iris holding area. These came from seeds at his nursery that resulted from his using the Captured Breading Process utilizing I. nelsonii iris pollen he collected at the Palmetto Island State Park boardwalk in 2021 with the permission of the park manager. He pollinated I. nelsonii irises that he had gotten from an iris collector many years ago.


Benton's donated irises will be planted at the park’s boardwalk this fall, but many will not be mature enough to bloom next spring. Efforts are underway to solicit donations of I. nelsonii irises from iris collectors to increase the number of blooming irises at the boardwalk next spring.

Photo: LICI's volunteer, Kent Benton, is seen collecting pollen from a few of the I. nelsonii irises blooming at the Palmetto Island State Park on March 23, 2023, during a visit to the park. He received permission from the then-manager of the park to collect pollen to use for producing more I. nelsonii irises to be planted at the boardwalk in 2024.


Benton collected more pollen from the irises at the park's boardwalk during the iris bloom in April 2023, but a late frost destroyed many of the flowers at his nursery soon after they were pollinated. The seeds to be created and grown out were to be planted at the boardwalk in the fall of 2024 in the hope that they would all bloom in April 2025.


LICI then proposed collecting seed pods from the actual I. nelsoniii irises growing in the Abbeville Swamp when they ripen in July to stay on track with having more irises to plant in the fall of 2024 at the park's boardwalk. The group's thinking is that almost all of these seeds would be wasted if they stayed in the swamp since the percentage of Louisiana iris seeds germinating, growing, and surviving into mature plants in the wild is extremely low.


The plan is for the irises from these collected seeds to grow in their natural environment in the Palmetto Island State Park boardwalk swamp, where the public can enjoy them while they bloom. But more importantly, after they are confirmed to be true I. nelsonii irises, they will be moved back into the Abbeville Swamp into areas where no irises are growing. "We can return to the Abbeville Swamp a much higher percentage of the seeds we collect as mature plants in 1 1/2 years compared to hoping the seeds germinate on their own in the swamp," LICI's Gary Salathe said when he announced the plan. Salathe heads up the project for LICI.

The photo on the left shows the 36" tall I. nelsonii irises blooming in one of the more remote areas the LICI volunteers found irises on their April tour of the Abbeville Swamp. The same area is shown on the right in July after 4 1/2 months of weed and swamp plant growth. The dormant irises and their ripe seed pods were covered by 48" tall weeds and brush.


After receiving the landowner's permission, LICI organized an iris seed pod collection expedition to the Abbeville Swamp on July 12, 2023. Unfortunately, it coincided with an extreme heat wave hitting the area. Over sixty seed pods were collected after four hours of tiring and dirty work in the scorching heat that involved whacking through brush and weeds to get to the irises and their seed pods.

The next day, on Thursday morning, July 13, 2023, during a presentation on germinating iris seeds given by Salathe to members of the Acadiana Native Plant Project, some seed pods were opened, and the seeds were planted into one-gallon pots. He taught the attendees Kent Benton's method of germinating seeds. The 455 seeds will be watched over and germinated by the group at their native plant nursery in Arnaudville, La.

Later that same day, near Livingston, La., Benton was given some seed pods to germinate the seeds. He reported that he had planted 465 seeds from the seed pods into pots the next day.

On Friday, July 14th, the rest of the seed pods were opened, and 474 seeds were planted into one-gallon pots by staff and interns of the Barataria-Terrebonne National Estuary Program (BTNEP) nursery in Thibodaux, La. They will germinate the seeds as a joint project with Nicholls Farm. The farm is managed by the head of the Biology Department of Nicholls State University, Dr. Quenton Fontenot, who is also LICI's contact with the university.

The groups agreed to help germinate the seeds when LICI determined that the irrigation system used at its iris-holding area for their mature irises would put too much water onto them.


"We are very excited that maybe a thousand or more of the very rare I. nelsonii irises will come from the 1,400 seeds planted into pots this week. We are very grateful for our friends and partners in this seed-germination project; Acadiana Native Plant Project, Kent Benton, and the Barataria-Terrebonne National Estuary Program in conjunction with Nicholls State University, " Salathe says.

All seedlings from the seeds will be returned to LICI in about five months to grow out at the group's iris-holding area in New Orleans. They will be ready to plant at the Palmetto Island State Park boardwalk in the fall of 2024.


"We hope that with more time available to plan our visit back to the Abbeville Swamp during next spring’s bloom, and with the permission of the landowner, of course, we may be able to significantly increase the number of seeds that we can collect next summer to farm out for germinating to boost the number of seedlings available for growing out even further, " Salathe says.


The hoped-for outcome of all of this work by all of the groups that are part of this project is to have a couple of thousand I. nelsonii irises blooming at the Palmetto Island State Park’s boardwalk by the spring of 2025.


Although awareness of the Abbeville Red irises at the Palmetto Island State Park will be elevated by the iris festival in 2025, the Vermilion Parish Tourist Commission has promoted the iris bloom at the park each spring. During a July meeting with the Executive Director of the Tourist Commission, Alison Miller, LICI committed to helping the Tourist Commission get the word out about the iris restoration project at the park and to increase awareness of the Abbeville Red irises while they bloom next spring. She said they regularly get people from all over the country to come into the visitor's center and ask about the Abbeville red irises, especially during the iris bloom each spring.

Starting next spring, and each year after, as all of the I. nelsonii irises are blooming at the Palmetto Island State Park's boardwalk, iris experts will be asked to walk through the swamp to verify that each iris is, in fact, a pure I. nelsonii iris. During the winter of the process will begin of returning many of the irises back to the Abbeville Swamp to be replaced at the boardwalk with a new crop of iris seedlings created using the prior year's seeds collected from the Abbeville Swamp. "We hope the boardwalk planting at the park will become a clearing house for irises grown from seeds collected from the Abbeville Swamp to be confirmed while they bloom so they can head back into the swamp as full-size plants," Salathe sums up.
