Discovering Trillium Species: Beauty in Diversity

A reflective springtime journey through Robert H. Treman and Fillmore Glen State Parks reveals the quiet beauty and botanical mysteries of red and white trilliums—exploring their species differences, color shifts, and the wonder of their ephemeral blooms.

Late April – Robert H. Treman State Park

I follow a winding trail through hemlock and maple woods, the air cool and earthy after a spring rain. Under the canopy of budding leaves, I spot a flash of deep burgundy among the moss. Kneeling, I find a red trillium blooming at the base of an old oak. Its three velvety petals are a rich wine color against the green moss and damp leaf litter. A faint musky scent wafts from the flower – no wonder some call it “Stinking Benjamin.” Nearby stands another trillium, but this one is a pristine white star facing upward toward the light. Its broad petals have a gentle wavy edge and no noticeable odor. The red flower droops modestly while the white one opens itself to the sky. Different in color and posture, I realize these are two distinct species1 sharing the same springtime stage.

Red trilliums (Trillium erectum) and white trilliums (Trillium grandiflorum) thrive side by side on the mossy roots of a tree. The maroon “wake robin” flowers nod toward the earth, while the white blooms stand upright to catch the light.

Seeing the red and white blooms side by side feels like meeting two woodland siblings – each unique yet part of the same family. The white trillium is almost luminous in the forest gloom, while the red trillium blends into the shadows with its dark hues. Both emerge from the soil after long, cold months, timing their bloom for the brief sunny window before the trees fully leaf out. Knowing how slowly these perennials grow and how long they live makes their yearly return even more special to witness. Their resilience in coming back each spring fills me with quiet awe.

Early May – Fillmore Glen State Park

A week later, I wander the lush gorge of Fillmore Glen. The trail is alive with birdsong and the rush of a creek. Dappled sunlight slips through the greening canopy, illuminating patches of the forest floor. Rounding a bend, I catch my breath — the hillside ahead is blanketed with hundreds of white trilliums, a breathtaking constellation of blooms across the ground that feels almost sacred. Careful not to tread on any, I step closer to admire them at eye level.

Up close, one large white trillium reveals a surprise: a delicate wash of pink across its aging petals, as if it were blushing. It’s known that after pollination the snow-white petals of Trillium grandiflorum often turn rose-pink with age2. Indeed, many blossoms here wear a faint pink tint, especially those that have been open for a while. This blush of maturity gives the colony a quietly celebratory air – fresh ivory blooms mingling with older siblings tinted softly rose.

The petals of a white trillium take on a soft pink blush as the flower ages, adding a new hue to the spring palette. Fresh white trilliums bloom in the background while older ones show a rosy tint.

In a shaded nook at the edge of the colony, a lone red trillium blooms among the white. I wonder if the red and white trilliums ever hybridize. I see no intermediate colors and recall that the white trillium rarely hybridizes with other species3. The red trillium, by contrast, can swap pollen with certain close relatives, yielding various forms elsewhere. But a true red–white cross never occurs here – each species keeps to its own.

Trillium bloom April through May in central New York State. I found these blooming on the rim of Fillmore Glen near Owasco Lake and the town of Moravia.

The red trillium even has a rare white-petaled form4 easily mistaken for its white-flowered cousin. I linger a bit longer among these graceful “trinity flowers,” my questions answered and my appreciation deepened. As I turn to go, a sunbeam breaks through and illuminates one last trillium by the trail, its white petals touched with pink. I smile, grateful for the chance to witness this woodland wonder.

Footnotes

  1. Different species: Red trillium and white trillium are separate species (Trillium erectum and Trillium grandiflorum, respectively), distinguished by traits like flower orientation and petal shapeidentifythatplant.com.
  2. White petals turn pink: The large white trillium’s petals are pure white upon opening but gradually develop a rose-pink or purple tint as the flower agesnj.gov.
  3. Rare hybridization: Unlike some trilliums that hybridize readily, Trillium grandiflorum (white trillium) is not known to form hybrids with other speciesen.wikipedia.org. Trillium erectum can hybridize with its close relatives, but a red–white trillium cross is not observed in nature.
  4. White form of red trillium: Trillium erectum (normally red) has a variety with white petals, classified as T. erectum var. album, which can be mistaken for a white trillium at a glancemidatlanticnature.blogspot.com.

Rumination on wild flower blooms

An access road, now blocked with huge boulders by the State Park, leads to this dam at the head of Fillmore Glen. I stop here for reflection at times and have climbed behind the dam for photographs. It is possible to drive up the south side of the glen on a poorly maintained road and park next to the boulders. In this season (spring) the surrounding forest is carpeted in wildflowers. Hepatica, trillium, dutchman’s breeches. One day, years ago, I pulled in behind a late model convertible with a license plate holder advising the owner was a member of the 10th Mountain division and a World War II veteran.

They were a well dressed and groomed couple. The white haired driver, in his late 80’s at least, patiently waited while she, a frail woman, walked the margins of the forest, enjoying the wildflowers. It was my impression this was a ritual for them, developed over the years. One of the few spring outings left to them.

Wildflower displays develop over hundreds of years. The massed trillium are on land not disturbed for thousands of years, since the last ice age. These same spring wonders were certainly enjoyed by the Iroquois before us.

On the gorge slope below the parking area, in a hollow on the north side of a large (I recall) oak, one early sunny spring morning I discovered the last resting place of a deer. Only the bones and some fur remained, the visible portion resembles the Capitulum and trochlea of a human arm bone and, indeed, there was a scapula close by. The season is evoked by the unfurling fern against the based of the oak.
