American Lotus: A Sacred Symbol of Beauty

American lotus, Nelumbo lutea, has been in bloom for a while now. It grows in a local wetland area and is a beautiful sight. This plant is prolific and has to be managed or it will over-take a wetland.

The plant's genus name, Nelumbo means "sacred bean. In many cultures the American lotus is sacred and a symbol of beauty.


It grows along the muddy shores of ponds, quiet streams, or rivers from the water's edge to a depths over 6 feet. The plant propagates from seed but also from rhizomes.


The crinkled leaf slowly opens during warm days and becomes a large pad with a depression in the center where the stem connects from underneath. The leaves are often a width of 1-2 feet. The leaves float on the surface or extend 1- 2 feet above the water.





Flower buds arise from the same root-stock as the leaves. The bud is large and egg- shaped, and encased in several layers of scales and sepals. In the center of each flower is a flat- topped, buttery colored receptacle. This is the pistil (the female parts), and clustered around it are dozens of yellow stamens (male). The flowers open in the morning and, at first, reveal only the female parts. This leads to cross-pollination because the insects that earlier visited older flowers with exposed stamens now crawl over the pistils of the young flowers.



 Each flower closes at night and lasts about 2 days. After the petals drop off, the center of the flower continues to grow and eventually reaches a diameter of about 3 inches. In this pod are about 20 holes, each containing a seed. The seedpods bend over and fall into the water where they will rot and release the seeds. In spring some of the seeds will begin to germinate, float to the surface, and drift ashore. Here, at the water's edge, a rhizome begins growing and a new plant begins its journey.




Beauty abounds in a pond or stream where the "Sacred Bean" grows-- a most definite symbol of beauty.

Wetland Plant Adaptations: Aerenchyma

In preparing for a educational workshop on wetlands, I collected a couple of wetland plants (American Lotus and Cattails) in order to illustrate the adaptations of these plants. Adaptations are the physiological, morphological, & reproductive characteristics that plants and animal have to survive in their specific environments.


There are three basic characteristics of that help define a wetland. (1) hydric soils (saturated soils), (2) hydrophytic plants (plants adapted to grow in wet/hydric soils, and (3) hydrologic regime (the presence of water over a period of time. In hydric soils, there is no oxygen so plants must thrive in anaerobic conditions. In order to do so, they have adaptations that allow them to  transport oxygen to their roots. One of those amazing adaptations is aerenchyma. Aerenchyma is the presence of air holes in the leaves, stems, and roots of aquatic plants.


Below are my photos of the seed head of American Lotus, aerenchyma of the stem of American Lotus, arenchyma in the stem of Cattail and then the leaves of Cattail.


I always marvel at the amazing adaptations that plants and animals possess.

Burkhart Creek Park Wetland Development

Recently I visited Burkhart Creek Park to check on the construction of the wetland. This is an area that was a wetland already but is being "enhanced" I do not have the history about it but when I find out, I will pass the info on here on my blog. These three photos below were taken on September 30, 2011.

Wetlands are my favorite habitat/ecosystem. There is such plant & animal diversity in these areas. I am excited and pleased that a wetland is being constructed here. I look forward to watching it develop and flourish. It will be a great place to photograph and study/observe. Below is an image I photographed on August 30, 2011 before construction. You can see wetland vegetation such as the willow trees, sycamores, and sedges & rushes.

Sycamore Land Trust: Beanblossom Bottoms Trail Native Seed Collection Workday

I woke at 6:30 a.m. yesterday to the coolest (I believe) morning so far since last spring-- 42 degrees. I drove to Bean Blossom Bottoms in Monroe County to assist in collecting native plant seeds and volunteer my photography services for Sycamore Land Trust. The seeds we collected today are to be used to restore the wetland area along the trail where they are eradicating invasive reed canarygrass.

Bean Blossom Bottoms consists of 570+ acres (with a two-mile loop of wooden pucheon and boardwalk) of diverse habitats which include emergent marsh, sedge meadows, hardwood forests, and old fields reverting to forest. Trees and shrubs in the bottomland include red osier dogwood, pin oak, American sycamore, green ash, buttonbush, white oak, and shellbark hickory. It is an Indiana Nature Preserve and certified as an Important Bird Area by the National Audubon Society.

Seeds from woolgrass (Scirpus cyperinus), buttonbush (Cephalanthus occidentalis), and several sedges were harvested. It was a gorgeous morning with plenty of wind and cool temperatures. The sunshine was comforting as we began collecting along the boardwalk and beyond.

My task (as well as a few other volunteers) was to collect woolgrass seeds. Once I would locate an inflorescence that had fully gone to seed, it was easy to strip the fine wooly seeds from the spiklets. Shaken or rolled between my fingers the seeds were like a downy powder or flour. Collecting was a meditation. For over three hours we harvested what will become new life in another area of the bottoms.

Sycanore Land Trust (SLT) is dedicated to preserving our disappearing landscape. I invite you to visit their website and become involved. If you value our local landscapes and their beauty speaks to you--- speak to SLT.

Burkhart Creek Park & A Little Frass

I visited Burkhart Creek Park on Saturday morning for some photography and nature study.  The park is located in Morgan County (Indiana) off State Road 67 on Duckworth Road. Burkhart Creek County Park is the first established county park and was opened in 2010 by the Morgan County Parks & Recreation Board. Currently the park has 1.5 miles of trails, picnic shelters, and tables for public use.

It was a lovely morning. I walked along the loop trail with the intention of investigating the area which will soon be an established wetland. It is obvious by the wetland plants present that this area is often wet. Of course we are behind on our needed precipitation this summer, so the area was devoid of standing water.

Thanks to the generosity of Mary A. “Sal” Hench, a lifelong philanthropist, a gift from Hench’s estate was
donated to the Community Foundation of Morgan County to be used to construct and preserve natural wetlands at Burkhart Creek County Park near Paragon.


A five (5) acre wetlands area will be created by the Wildwood Dam Conservancy District as an effort to ensure the survival of Wildwood Lake. With the assistance from the Hench gift, a variety of educational opportunities will become available for exploring wetlands plant and animal life. (Info from Community Foundation of Morgan County website).

I am drawn to wetland areas and have studied and photographed them for many years. I am thrilled that this wetland area will be enhanced and available for educational purposes. Thank you to Mary "Sal" Hench and her family for their generosity and foresight.

During my short visit I watched bluebirds, Carolina chickadees, blue-gray gnatcatchers, pileated woodpeckers, red-wing blackbirds and numerous butterflies. Below is an image of the proposed wetland area. Note the wetland loving vegetation already present.

Below is a photo I also took of a Japanese Beetle. Note the material protruding from the rear abdomen of the insect. I believe this would be frass-- insect excrement. So for all of you who wonder what insect excrement looks like or what the correct term is . . . here you go!

I encourage those of you who live in and around Morgan County to stay informed about Burkhart Creek Park. It is a work in progress and is evolving. The County Park Board meets once a month alternating between locations in Martinsville and Mooresville. The public is always welcome.

I would love to see more green spaces and especially nature parks here in our county. Support your local natural areas! Get outdoors!

Beauty in a Retention Pond: Lotus & Water Lilies

Beauty. I am always in search for beauty--the obvious and the not so obvious. I discovered beauty in a retention pond in Brownsburg (at least I assume it is a retention pond--right next to a road in a subdivision). I have never seen a RP that was beautiful. Most are mowed to the edge with no wetland vegetation. No management for diversity of vegetation or control of runoff of water or any chemicals. This one is very different.

The water was filled primarily with Lotus and Water Lilies around the edges. These are some of the most beautiful plants and a favorite of mine.

These images speak for themselves.
