The Wonder of Purple-Flowered Raspberry: Nature’s Thornless Native Treasure

The purple-flowered raspberry is a native shrub that confounds expectations, combining rose-like blossoms, maple-shaped leaves, edible fruit, and thornless stems into one of eastern North America’s most enchanting woodland plants.

I first encountered the purple-flowered raspberry while walking the Gorge Trail at Fillmore Glen State Park. Dry Creek murmured below, working patiently within ancient shale walls that confine its course. Waterfalls spilled from ledges overhead, cool mist drifted through the narrow passage, and sunlight filtered down in shifting patches through the summer canopy. It was a landscape dramatic enough to command all of one’s attention.

Yet it was a flower growing quietly beside the trail that stopped me in my tracks.

Purple-flowered Raspberry Growing Within Treman Gorge by the South Rim Trail

At first glance, I thought I had stumbled upon an escaped garden plant. The blossoms were  impossible to ignore—large, open, and an exuberant shade of rose-purple that glowed against the surrounding green. They seemed too extravagant for the subdued palette of a northeastern woodland. The petals had the simple elegance of wild roses, but there was something else about the plant that resisted easy identification.

The purple-flowered raspberry, Rubus odoratus, is a plant of delightful contradictions. Its blossoms are among the largest in the raspberry family, often two inches across. They appear over an extended season, beginning in early summer and continuing well toward autumn. Unlike the brief fireworks of many woodland wildflowers, this plant stages an encore performance, offering fresh blooms long after others have taken their final bow.

Over the years, I returned often to Fillmore Glen. Dry Creek became an old acquaintance, its voice changing with the seasons—boisterous after spring rains, subdued during the heat of late summer. And almost every year, somewhere along the Gorge Trail, I would encounter those same remarkable shrubs. Familiarity deepened into appreciation, and appreciation eventually became affection.

The flowers also serve a practical purpose beyond their beauty. Native bees and other pollinating insects visit them regularly, gathering nectar and pollen throughout the season. The plant has become part of an intricate ecological conversation that has been unfolding for thousands of years.

Then there are the leaves. The first time I noticed them closely, they triggered another moment of confusion. Broad and softly textured, divided into five lobes, they looked uncannily like oversized maple leaves. Some can grow nearly ten inches across, creating islands of lush greenery along shaded streambanks and woodland edges.

It is as though nature, in one of her playful moods, decided to combine the leaf of a maple, the flower of a rose, and the fruit of a raspberry.

Most raspberries and blackberries demand respect from a distance. Their prickles and thorns snag clothing and skin with equal enthusiasm. Purple-flowered raspberry breaks that expectation as well. Its stems are fuzzy rather than fierce. There are no hooked defenses waiting to punish curiosity. The plant invites close examination.

By late summer, the blossoms yield to flattened red fruits. Technically, they are raspberries, though they lack the sugary richness of their cultivated cousins. I have sampled them occasionally, appreciating them more for the experience than the flavor. Birds, however, are less discriminating. The fruits provide nourishment for wildlife, becoming another thread in the web of life that surrounds Dry Creek and countless other woodland habitats.

Native to eastern North America, purple-flowered raspberry ranges from Nova Scotia westward into Ontario and Wisconsin, extending south through the Appalachian Mountains. It thrives along forest margins, rocky slopes, stream corridors, and disturbed areas where sunlight penetrates the canopy. Through underground shoots, it gradually forms colonies that stabilize soil and provide shelter for small creatures.

It belongs exactly where I first found it. There is a temptation, especially among gardeners, to seek novelty elsewhere—to import the exotic, the unusual, the unfamiliar. Yet some of the most extraordinary plants are those that have quietly shared our landscapes all along.

The purple-flowered raspberry reminds me of this truth each time I encounter it. It teaches the value of paying attention. A hurried walk through Fillmore Glen might focus exclusively on the waterfalls, the sculpted rock formations, or the cool refuge of the gorge itself. All are worthy of admiration. But along the margins of the trail stand these shrubs, offering their own quieter marvels.

My photograph captures all flowering forms of this member of the Rose family. This specimen was blooming in August within the shade of Fillmore Glen in the Finger Lakes of New York State.

A rose-colored flower where one expects white. Maple leaves on a raspberry cane. Soft stems where thorns should be. Fruit that feeds the forest. A native plant that asks for nothing more than the chance to flourish where it has always belonged. Years after that first encounter beside Dry Creek, the sight of those blossoms still stops me as I find them in all the Finger Lakes gorges.

Certain plants become landmarks in our personal geography. They root themselves not only in the soil but in memory. The purple-flowered raspberry has become one of those companions for me—a recurring presence marking the passage of summers, a familiar face in a beloved landscape.

Dry Creek continues its patient work of carving stone. The waterfalls continue to descend in silver ribbons through the gorge. And each year, as if renewing an old friendship, the purple-flowered raspberries lift their improbable blossoms toward the filtered light. In their presence, wonder becomes less an emotion than a habit of attention.

Sometimes the greatest discoveries are not rare because they are hidden. They are rare because we have not yet learned to see them. The purple-flowered raspberry taught me to look more closely. Along a trail I thought I knew by heart, it revealed that nature still keeps delightful surprises in reserve.

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.

Click me for my Getty flower photography.

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.

Ghost Pipes that grow in the dark

chlorophyll free

I found these popping up from leaf litter, a mixture of last year’s maple and elm, on an August morning. The dappled light, varied from bright to very dark, exceeded the dynamic range of my equipment, so I set up the Sony dslr Alpha700 with the Sony lens DT 18-200mm f3.5-6.3 on a tripod and, using the remote feature, placed the flash at an optimal angle.

Monotropa uniflora, also known as ghost plant, ghost pipe, or Indian pipe, is an herbaceous perennial plant native to temperate regions of Asia, North America, and northern South America, but with large gaps between areas. The plant is sometimes completely waxy white, but often has black flecks or pale pink coloration. Rare variants may have a deep red color. The name “Monotropa” is Greek for “one turn” and “uniflora” is Latin for “one flowered” as there is one sharply curved stem for each single flower. It flowers from early summer to early autumn, often a few days after rainfall. The fruit, an oval capsule-like structure, enlarges and becomes upright when the seeds mature, at this point stem and capsule looking desiccated and dark brown or black. The seeds of Monotropa uniflora are small, ranging between 0.6–0.8 mm (3⁄128–1⁄32 in) in length.

Unlike most plants, it is white and does not contain chlorophyll. Instead of generating food using the energy from sunlight, it is parasitic, and more specifically a mycoheterotroph. Its hosts are certain fungi that are mycorrhizal with trees, meaning it ultimately gets its food from photosynthetic trees. Since it is not dependent on sunlight to grow, it can grow in very dark environments as in the understory of dense forest. The complex relationship that allows this plant to grow also makes propagation difficult.

The flowers of Monotropa uniflora are visited by various bee and fly species, most commonly bumblebees. Bumblebees are an important pollen dispersal agent for the plant.

Like most mycoheterotrophic plants, Monotropa uniflora associates with a small range of fungal hosts, all of them members of Russulaceae.

It is often associated with beech trees.

The plant contains glycosides and may be toxic to humans.

In addition to various reported medical uses, the plant has been used as an anxiolytic in herbal medicine since the late 19th century.

Hepatica acutiloba

Old Leaves

This Hepatica acutiloba, the sharp-lobed hepatica, I found in Fillmore Glen last April, capturing them with the Apple Iphone 14 proMax.

Hepatica acutiloba is also known as sharp-lobed hepatica, liverwort, kidneywort, pennywort, liverleaf. The perennial nature of this plant is seen here in the purplish leaves hanging below, from a previous year’s growth.

The word hepatica derives from the Greek ἡπατικός hēpatikós, from ἧπαρ hêpar ‘liver’, because its three-lobed leaf blotched leaves resemble a diseased human liver.

Hepatica Gone To Seed

AKA liverleaf

This Hepatica acutiloba, the sharp-lobed hepatica, I found in Fillmore Glen last April, capturing them with the Apple Iphone 14 proMax.

“’The liverleaf puts forth her sister blooms of faintest blue soon after the late snows have melted. Indeed, these fragile-seeming, enable-like flowers are sometimes found actually beneath the snow, and form one of the many instances which we encounter among flowers, as among their human contemporaries, where the frail and delicate-looking withstand storm and stress far better than their more robust-appearing brethren.” 

Click for my Fine Art Photography Gallery.

Each clump-forming plant grows 5 to 19 cm (2.0 to 7.5 in) tall, flowering in the early to mid-spring. The flowers are greenish-white, white, purple, or pinkish in color, with a rounded shape. After flowering the fruits are produced in small, rounded columned heads, on pedicels 1 to 4 mm long seen here in these gone to seed flowers. When the fruits, called achenes, are ripe they are ovoid in shape, 3.5–4.7 mm long and 1.3–1.9 mm wide, slightly winged and tend to lack a beak.

“The rusty leaves of last summer are obliged to suffice for the plant’s foliage until some little time after the blossoms have appeared, when the young fresh leaves begin to uncurl themselves.  Someone has suggested that the fuzzy little buds look as though they were still wearing their furs as protection against the wintry weather which so often stretches late into our spring.”

Hepatica cultivation has been popular in Japan since the 18th century (mid-Edo period), where flowers with doubled petals and a range of color patterns have been developed.

Noted for its tolerance of alkaline limestone-derived soils, Hepatica may grow in a wide range of conditions; it can be found either in deeply shaded deciduous (especially beech) woodland and scrub or grassland in full sun. Hepatica will also grow in both sandy and clay-rich substrates, being associated with limestone. Moist soil and winter snowfall are required; Hepatica is tolerant of winter snow cover, but less so of dry frost.

Propagation is done by seeds or by dividing vigorous clumps in spring. However, seedlings take several years to reach bloom size, and divided plants are slow to thicken.

Hepatica was once used as a medicinal herb. Owing to the doctrine of signatures, the plant was once thought to be an effective treatment for liver disorders. Although poisonous in large doses, the leaves and flowers may be used as an astringent, as a demulcent for slow-healing injuries, and as a diuretic.

Keep Your Pants On

Dutchman’s breeches

Dutchman’s Breeches (scientific name: Dicentra cucullaria). Dicentra cucullaria is dependent on bumblebees (especially Bombus bimaculatus, a common eastern North American species) for cross-pollination. In fact, the flower structure and mechanism by which it is pollinated indicate that it is adapted for bumblebees, which can separate the outer and inner petals of the flower. They will then use their front legs to expose the stigma, stamen, and anthers. Shortly afterwards, they will sweep pollen in a forward stroke by utilizing their middle legs, before leaving the flower to return to the colony with the pollen. In this way, Dicentra cucullaria is pollinated as the bees move from plant to plant, and the bumblebee meets its dietary needs. The effect of a hallucinogenic compound contained in the plant on livestock has led ranchers to refer to it as ‘Staggerweed’.

Click for my Fine Art Photography Gallery.

Dutchman’s breeches were likely introduced to cultivation in England when Philip Miller introduced it to the Chelsea Physic Garden. Miller likely received it from John Bartram. The species was, however, not mentioned in American horticultural literature until the early 19th century. Two clones with pink flowers have received cultivar names: ‘Pittsburg’, which turns pink under certain conditions, and ‘Pink Punk’, collected by Henrik Zetterlund on Saddle Mountain in Oregon, is more consistently pink.

Native Americans and early white practitioners considered this plant useful for syphilis, skin conditions and as a blood purifier. Dutchman’s breeches contain several alkaloids that may have effects on the brain and heart. However, Dicentra cucullaria may be toxic and causes contact dermatitis in some people.

Not Guilty

…for lack of evidence

Greater Bee Fly is reputed to be a nectar thief, making a cut in flower base to siphon off nectar without fertilizing the flower. This behavior is not in evidence here as it approaches this Carolina spring beauty on a late April afternoon along the South Rim trail of Fillmore Glen State Park.

Click for my “Finger Lakes Memories” Fine Art Photography Gallery.

Instead, what we see is this fly using a long rigid proboscis, found in the front of the head, to probe and feed nectar from the flower base as would any other respectable bumblebee that is resembles and is commonly mistaken for.

A Beauty

…and an edible plant

Claytonia caroliniana, the Carolina Spring Beauty, is an herbaceous perennial in the family Montiaceae. It was formerly placed in family Portulacaceae. Its native range is eastern and central North America. It is most found in the New England area of the United States, but its habitat extends from Ontario and a northern limit in the Cape Anguille Mountains of Newfoundland and south to Alabama.

Click for my “Finger Lakes Memories” Fine Art Photography Gallery.

Description

It grows approximately 6 inches tall in forests of the Appalachian Mountains and piedmont.Claytonia caroliniana is a flowering, woodland perennial herb. It grows from March though June and is one of the earliest spring ephemerals. The plant grows from spherical underground tubers in light humus. They sprout and bloom before the tree canopy develops. Once the area is shaded, the plants whither leaving only the tuberous roots underground.

The flowers consist of five pink and purple petals. Dark pink veins accent the petals and give them a striped appearance. The carpels are fused together. I have heard the flowers are white when first opened, have not experienced this myself. They grow on a stem 3 – 10 inches tall that bears a single pair of broad leaves. There are two green leaves that grow opposite each other on a node. The leaf has no teeth or lobes and a prominent central vein. They grow up to three inches long and 1/2 to 3/4 inches wide.

In the photograph, Carolina Spring Beauty flowers bracket the leaves just visible under leaf litter.

Edible

The plant is edible, but its usability is limited due to difficulty harvesting and the small quantities each plant produces. Its tuberous roots are edible and rich in starch and can be cooked or eaten raw. The leaves can be eaten as well. The tuberous roots are eaten by eastern chipmunks and white-footed mice.

History

The plant was named after John Clayton. Clayton was an early collector of plant specimens.

Not a Bee

…and an edible plant

Bombylius major (commonly named the large bee-fly, the dark-edged bee-fly or the greater bee fly) is a parasitic bee mimic fly. Bombylius major is the most common type of fly within the Bombylius genus. The fly derives its name from its close resemblance to bumblebees and are often mistaken for them.

Click for my “Finger Lakes Memories” Fine Art Photography Gallery.

Bombylius major exhibits a unique flight behavior known as “yawing” and plays a role in general pollination, without preference of flower types. The fly does not bite, sting, or spread disease. However, the fly uses this mimicry of bumblebees to its own advantage, allowing close access to host solitary bee and wasp nests to deposit its eggs. After hatching, the larvae find their way into the nests to parasitically feed on the grubs.

Flight


It has been discovered that the fly is capable of a unique behavior, which was discovered with the use of a high speed camera. In this behavior, the flies are seen to rotate around a vertical axis as they fly (this action is known as “yawing”). However, it is still unknown what can cause this behavior to be triggered and what purpose it serves, but a proposed explanation includes mating habits. Here is an illustration of “Yaw” in the context of an airplane…substitute the fly body with head facing forward (to left).

Pollinator Role


The Bombylius major bee-fly is a common, generalist floral pollinator, meaning that it does not give preference to one flower over another, instead pollinating a wide variety of plant families and species. The fly uses its proboscis to carry and transfer the pollen. The species is a dominant pollinator within its community, sometimes even pollinating up to two thirds of the local flowers. In addition, Bombylius major will visit and pollinate plants that attract few other species. Some types of flowers, for example Pulmonaria officinalis, will be almost exclusively pollinated by Bombylius major, with other species contributing a negligible amount to that plants pollination. Some flower species, such as Delphinium tricorne, are even specifically adapted to the fly in terms of color, shape, and form. If given the choice, Bombylius major will have a consistency in plant choice.

Flower Attraction


Long distance floral attraction is governed by optical sense, with color being the most important factor. The flies are typically more attracted to blue and violet colors, and occasionally yellow, over orange and pink. However, short distance floral attraction is based on the fly’s olfactory sense.

Sunbathing Activity


The fly is mostly active during day hours when the weather conditions are warm and sunny. Bombylius major is attracted to sunnier places and is more likely to pollinate these areas, with a larger average of flower visits in areas of higher amounts of sunshine. The fly will hide in the trees during the night and usually dart away from a cast shadow and occasionally hide in clean washing brought in fresh from the washing line and fly out causing unsettled behavior in the discoverer.

Flower Description


Claytonia caroliniana is a flowering, woodland perennial herb. It grows from March though June and is one of the earliest spring ephemerals. The plant grows from spherical underground tubers in light humus. They sprout and bloom before the tree canopy develops. Once the area is shaded, the plants whither leaving only the tuberous roots underground.
