Don Croner’s Wanders on the Great Allegheny Passage Bike Trail (GAP) | Flora | Bee Balm
The plant is also known as Oswego tea. The Oswego Native Americans around the Oswego River in upstate New York used an infusion of the flower and leaves to treat a variety of ailments, including coughs and colds, fever, abdominal pains, and flatulence, and in a poultice to treat sore eyes. They also used it in cooking to flavor game, especially birds, and drank infusions of the leaves as a beverage. Early European settlers learned this latter usage from them and after the Boston Tea Party, when imported tea was boycotted, adopted it as a local substitute, calling it “Oswego tea” (please keep in mind that the only true tea is made from the tea plant, Camellia sinensis). Bee balm is also known as bergamot, but it should not be confused with another plant known as wild bergamot (Monarda fistulosa), which has lavender-colored flowers instead of the distinctive scarlet flowers of Monarda didyma.
Nor should bee balm, Oswego tea, or bergamot be confused with the bergamot citrus tree, a native of southern Italy. An essential oil from the peel of the fruit of the bergamot orange tree is used as a flavoring in the famous Earl Grey tea blend. The taste of bee balm has an almost uncanny similarity to the taste of the bergamot orange, and thus the native American plant also became known as bergamot. The dried leaves of bee balm mixed with loose black tea will produce a brew that can be differentiated from Earl Grey tea only by hard-core tea cognoscenti. Infusions and tinctures of bee balm alone are used to treat indigestion and nausea, intestinal cramps, and diarrhea. Bee balm also serves as a nervine tonic and relaxant, exerting a calming effect on the nervous system without causing excessive sedation. The plant also has great aesthetic value, with its lovely scarlet flowers brilliantly festooning the edges of the GAP.

Don Croner’s Wanders on the Great Allegheny Passage | Flora | Red Columbine
Native Americans, specifically the Meskwaki people, added columbine seeds to smoking blends, and other tribes used the crushed seeds as a perfume and in love charms. Native Americans also used the seeds, roots, flowers, and leaves for various medicinal purposes, including kidney and urinary ailments, and stomach aches. European colonists used the plant for gallbladder disorders and relief of general stomach and intestinal problems.
The entire plant does contain various toxic compounds, and the borderline between medicine and poison is difficult to define—it has been known to poison rabbits—and most modern herbalists seem to shy away from it, since safer alternatives are available. Also, it usually does not occur in great quantities, making it best enjoyed for the aesthetic qualities of its gorgeous flowers.

Don Croner’s Wanders on the Great Allegheny (GAP) Bike Trail | Flora | Black-eyed and Brown-eyed Susans
Two Susans occur along the GAP:
Black-eyed Susan (Rudbeckia hirta)
Botanical Classification
- Scientific name: Rudbeckia hirta
- Family: Asteraceae (Aster/Sunflower family)
- Life cycle: Biennial or short-lived perennial (sometimes behaves as annual)
Physical Characteristics
Size:
- Height: 2-4 feet (60-120 cm)
- Spread: 1-2 feet (30-60 cm)
Flowers:
- Size: Large—2.5-4 inches across (6-10 cm)
- Ray petals: Yellow, golden-yellow to orange (8-21 rays)
- Center disk: Dark brown to black, dome-shaped and prominent
- Bloom time: June to October (late summer through fall)
- Fewer but larger flowers per plant
Leaves:
- Basal leaves: 10-18 cm long, mostly unlobed
- Larger leaves overall (3-7 inches long)
- Covered in coarse, stiff hairs giving rough texture
- "Hirta" means "hairy" in Latin—referring to the bristly trichomes
Stems:
- Stout, branching, hairy stems
- Usually over 8 inches long
Habitat & Distribution
- Native to eastern and central North America
- Found in all 48 contiguous states and all 10 Canadian provinces
- Grows in prairies, meadows, roadsides, disturbed areas
- Tolerates: Heat, drought, poor soil, wide pH range
- State flower of Maryland
Brown-eyed Susan (Rudbeckia triloba)
Botanical Classification
- Scientific name: Rudbeckia triloba
- Family: Asteraceae (Aster/Sunflower family)
- Common names: Brown-eyed Susan, three-lobed coneflower, thin-leaved coneflower, branched coneflower
- Life cycle: Biennial or short-lived perennial
Physical Characteristics
Size:
- Height: Taller—2-5 feet (can reach up to 5 feet
- Spread: 1-1.5 feet (narrower than black-eyed
- Bushy, open, branched appearance
Flowers:
- Size: Smaller—1-2 inches across (about 1/3 the size of black-eyed)
- Ray petals: Deep golden yellow, 6-13 shorter, wider rays
- Center disk: Dark purple-brown to jet-black, button-shaped, flattened cone (slightly lighter than black-eyed)
- Bloom time: Later season—late summer through fall (July-October), until hard frost
- More numerous flowers covering the entire plan
- Longer blooming period
Leaves:
- Distinctive three-lobed basal leaves (hence "triloba")
- Upper leaves: Smaller, lance-shaped, often unlobed
- Thinner, more delicate leaves than black-eyed
- 2-4 inches long, ½-2 inches wide
- Covered in bristly hairs but less coarse than black-eye
Stems:
- Many-branched stems creating masses of flowers
- Bristly hairy, often reddish-green
- "Country cousin" appearance—more sprawling
Habitat & Distribution
- Native to eastern and central United States (New York to Florida, west to Minnesota, Utah, Texas)
- Prairies, woodland borders, thickets, rocky slopes, roadsides
- Prefers moist soil but adaptable
How to Tell Them Apart in the Field
Quick Visual Cues:
1. Flower size is the giveaway
- If the bloom is as big as your palm → Black-eyed Susan
- If the bloom is 1/3 that size → Brown-eyed Susan
2. Look at the leaves
- Large, hairy, mostly unlobed → Black-eyed Susan
- Three-lobed basal leaves, thinner overall → Brown-eyed Susan
3. Count the flowers
- A few big, bold flowers → Black-eyed Susan
- Plant covered in masses of smaller flowers → Brown-eyed Susan
4. Growth habit
- Sturdy, upright, well-behaved → Black-eyed Susan
- Bushy, branching, sprawling → Brown-eyed Susan
Ecological & Garden Value
Both species are outstanding for:
- Naturalized plantings and meadows
- Pollinator gardens
- Native plant gardens
- Cottage gardens (especially brown-eyed)
- Roadsides and disturbed areas
- Prairie restoration
- Butterfly gardens
- Cut flower gardens
Historical/Medical Note: Native Americans used Rudbeckia hirta medicinally, though the plant is toxic to cats. Both species have been used in folk medicine.
Along the GAP
Given that the Great Allegheny Passage runs through prime habitat for both species—disturbed roadsides, woodland edges, open meadows, old fields—you'll encounter both along your journey.
Look for:
- Black-eyed Susan (R. hirta) in sunnier, more open areas with those big, bold 3-4 inch flowers
- Brown-eyed Susan (R. triloba) in slightly shadier woodland borders and thickets, creating clouds of smaller blooms in late summer
Both are quintessential late-summer sights along the GAP—cheerful yellow beacons that brighten the landscape just as other wildflowers are fading into autumn.
