Step into the spring woods and discover the broadleaf toothwort, Cardamine diphylla. Marvel at its white blossoms and deep-lobed leaves, and uncover its vital role in both early pollination and traditional medicinal practices.
Broadleaf toothwort, Cardamine diphylla, plays a charming role in the ecosystem of deciduous forests, often carpeting the forest floor with its distinctive greenery and white blossoms during the spring. This plant is particularly noted for its broad, compound leaves that usually consist of two or three leaflets, each characterized by deep lobes and a somewhat wrinkled appearance, lending it the name “crinkle root.”
The flowers of the broadleaf toothwort are a notable feature, emerging in clusters atop slender, upright stems. Each bloom presents four white petals that form a delicate cross, a typical trait of the Brassicaceae family, to which it belongs. The flowering period spans early to mid-spring, making it one of the earlier blooms in woodland areas, which plays a critical role in the local ecology. These flowers are not just a visual treat but are also vital for early-season pollinators such as bees and butterflies, providing them with necessary nectar.
Moreover, Cardamine diphylla is more than just a visual and ecological gem. It has historical uses in traditional medicine and cuisine. Native American tribes utilized the peppery roots of the toothwort as a seasoning and as a medicinal herb to treat various ailments.
The presence of Cardamine diphylla is also an indicator of the health of the forest ecosystem. Thriving populations of this plant suggest a well-preserved habitat, which is crucial for biodiversity conservation.
In summary, Cardamine diphylla, with its ecological significance and historical uses, represents a small but vital part of North America’s natural heritage, highlighting the intricate connections within woodland ecosystems and the importance of preserving these natural environments.

Hepatica blossoms are the focal point here. Two land snail shells rested fortuitously below, a white and dark brown. The white shell (Scientific Name: Neohelix albolabris) is seen here. In life, the shell aperture reflective lip gives the species name, from Latin root words “albo” (white) and “labris” (lip), and the popular name, “Whitelip.” Look closely to see a series of ridges, an identifying feature apparent in this specimen. There was a live specimen in our yard, just yesterday. Busy with chores, no camera at hand.

Nature’s artistry unfolds on the shores of Cocoa Beach, where the ever-changing tides leave intricate patterns in the sand. This captivating display of erosion hints at a fragile coastline, urging us to act for its preservation.
Standing on the sandy shore of Cocoa Beach in January 2024, I observe firsthand the effects of erosion along this stretch of Florida’s coastline. The scenes captured in my photographs show significant changes to the beach’s contours and composition. The shimmering foam, soft sand ripples, and exposed shells are testament to the relentless activity of the sea. Each wave carves away at the beach, leaving patterns in the sand that tell the story of erosion.
Erosion Patterns and Sea-Level Rise
The photographs vividly display the intricate, almost artistic designs formed by erosion. In one, the ripples in the sand reflect the movement of the water, indicating the direction and flow of the tides. The sea has steadily eaten away at the shoreline, pulling the sand away with each ebb and flow.
Macro, erosion patterns in beach sand.
Studies show that Florida’s Atlantic coast is particularly susceptible to rising sea levels due to its low-lying nature. The Florida Climate Center notes that sea levels have been rising at an average rate of about 1 inch per decade, with projections estimating further acceleration. April 27, 2024 The Washington Post published, “Where Seas are Rising with Alarming Speed,” showing a map with Cape Canaveral / Cocoa Beach showing a 6 – 9 inch sea rise since 2010. This rise compounds the effects of erosion, causing beaches like Cocoa Beach to recede.
Impact on the Beach
I notice shelves of beach sand formerly above the tide now washed over by high tide. New channels forming, cutting across the sand with each tidal cycle. The erosion reveals underlying shell beds and deposits, hinting at the rapid loss of the finer, upper layers of sand. This accelerated erosion poses a significant risk to the stability of the coastal area.
The erosion is not just cosmetic. It impacts local ecosystems and property lines, potentially leading to habitat loss and increased vulnerability to storm surges. Coastal development also exacerbates the problem by interfering with natural sediment replenishment.
Reflections and Future Prospects
The view across the horizon, where the deep blue sea meets the sky, is a stark reminder of nature’s power and the urgent need for mitigation. As Florida’s beaches face the twin challenges of rising seas and intensifying storms, the communities here must find ways to adapt. Cocoa Beach is a vivid reminder of the coastal fragility and the importance of sustainable management practices.
From a personal perspective, seeing this change compels a deeper reflection on our relationship with nature. The beaches we walk on today may not be here for future generations unless we act decisively to combat climate change. Efforts to build resilience into coastal infrastructure and adopt environmentally friendly practices will play a critical role in preserving this natural beauty.
Conclusion
In summary, Cocoa Beach’s erosion is a direct consequence of rising sea levels and changing environmental conditions. The patterns etched in the sand speak of nature’s resilience and power, while also sounding an alarm about the future. As stewards of the coast, it is our responsibility to take meaningful actions that preserve these shores for generations to come.
Afternoon, May 5th last week was spent in Fillmore Glen New York State Park, Moravia New York. Back in 2002, this was my first wildflower photography experience and repeated many times over the years (Click me for another Hepatica posting). Here is a follow-up showing the next step in the development of Hepatica blossoms, forming seed heads.
Here you see both flowers and a single seed head set in three bracts.

Seconds after taking this shot, at f/4, I changed the f-stop to 29 and captured these blossoms with the environment in focus (yesterday’s posting). At f/4 focus is a challenge and I was not happy with the detail of the foreground blossom.

I am in the experimentation phase of learning the new camera, so in spite of the 100% file size increase I turned on the Dual Pixel Raw feature. The two photos are from the same file. My impression is the adjustment improved the foreground flower details. Is it my imagination?
This afternoon’s sky was overcast, perfect for photographing wildflowers: clouds thin enough for light to pour through. In the clouds’ shadow there is not enough light for the plant to cast its own distracting shadows. Compare an earlier trillium photograph (click me to go there).
For the following photograph is a study in habitat. At f32, focusing on the trillium, the surroundings are clearly identifiable: several budding Foam Flower heads (Scientific Name: Tiarella), fern, rotting wood, the forest floor hidden by leaf clutter.
I released the shutter (with a 2 second delay) during a break in spring breezes, the overcast lighting bright enough for a speedy 1/8 second exposure. The focus on the opening trillium bloom is just as crisp in this exposure as the next.

f32 / 1/8 second
At 4 f-stop, the entire plant is in focus while many habitat elements are a soft blur. An interesting point is the leaf on the left. It is in focus somewhat and is a distraction. This was an issue, in my opinion, for the first photograph.
Hepatica positioned perfectly above the trail, sprouting from moss, a grouping of the plant and flowers.
Scientific Name: Hepatica nobilis var. obtusa. I found the two land snail shells this session, I identified it as Neohelix albolabris, and positioned it in this shot to lend interest. In a future posting you will see the shell where it was found.

Hepatica Blossoms
Six unrelated young adults, all female and without masks, not following social distancing guidelines, passed as a group just before I set up for this shot. I heard them coming and made plenty of space between them and me. COVID-19 testing in Tompkins continues to find several positive cases each week.
Finding an appropriate combination of settings for this grouping was a puzzle. My goal was to bring the flowers and surrounding into focus with intermittent breezes. The f-stop needed to be high to accommodate the depth with minimal exposure duration as the flowers moved in the slightest breeze. The solution was a high ISO (2500) and f-stop (32), yielding a 1/3 second exposure (Not fast). The compromise was patiently waiting for a break in the breezes.

Just opened flowers on long hairy stems, tiny anemones. A crawl and tripod we needed to capture these. The scene scale is revealed by the dried leaves from last autumn.

Hepatica Blossoms
I call these anemones from the disputations among taxonomists. All agree there is some relationship and differ in the degree. Classifications add a designation “tribe” before genus (hepatica). Alternatively, the genus is designated Anemone instead of Hepatica . A common name for anemones is “wind-flower” for how the flower is sensitive to a slight breeze, on these long stems.
This is the first hepatica capture of the session. There was no breeze at this time and the ISO is 800, f-stop 29 (lending some definition of the background, less than I’d expect) and a relatively slow exposure of 1/4 second. The 100 mm macro lens on a tripod mounted camera.
