About Scarlet Beebalm

Monarda didyma, commonly known as bee balm, Oswego tea, or bergamot, is a clump-forming perennial in the Lamiaceae family native to eastern North America. It reaches 60–120 cm tall with square stems, aromatic lance-shaped leaves, and spectacular whorled flower heads in shades of red, pink, purple, or white. The tubular florets are irresistible to hummingbirds, butterflies, and bees.

Bee balm thrives in USDA zones 3–9, preferring moist, fertile soil in full sun to light shade. Good air circulation is essential because the species is prone to powdery mildew—mildew-resistant cultivars like 'Jacob Cline' and 'Raspberry Wine' are recommended. Divide clumps every 2–3 years to maintain vigour and prevent the centre from dying out. Deadheading prolongs bloom from midsummer into early autumn.

The leaves brew a pleasant, mildly citrus tea that the Oswego people of New York shared with early colonists—hence the common name. During the Boston Tea Party era, Oswego tea became a patriotic substitute for imported black tea. The plant is also used to flavour salads and as a garnish. In the ornamental garden, red bee balm is unsurpassed for attracting ruby-throated hummingbirds and makes a stunning mid-border statement.

History

Illustrated historical scene for Scarlet Beebalm

Monarda didyma is native to the moist woodlands and streamsides of eastern North America from southern Canada through the Appalachians. It was used by numerous Indigenous peoples — particularly the Iroquois-affiliated Oswego nation of upstate New York — as a medicinal and beverage tea. The genus honors the 16th-century Spanish physician-botanist Nicolás Monardes, who catalogued New World plants despite never visiting America.

After the Boston Tea Party of 1773 and subsequent colonial boycott of British tea, American colonists adopted M. didyma as "Oswego tea," learning the preparation from the Oswego people. It was exported back to Britain as a patriotic curiosity. The plant's name "bee balm" reflects the intense pollinator activity it attracts — hummingbirds in particular swarm the red-flowered forms.

Modern cultivars include mildew-resistant strains developed by the US National Arboretum and include "Jacob Cline," "Marshall's Delight," and the "Grand" series. The Oswego Nation taught colonists to brew the plant's leaves as tea. After the Boston Tea Party (1773), Americans adopted Oswego tea as a boycott alternative to British imports. John Bartram sent seeds to England in the 1740s, launching its European garden career.

Symbolism & meaning

What It Symbolizes

Scarlet Beebalm is compassion in color. The Oswego people shared its fragrant leaves with settlers, and the plant later lent its flavor to a tea of independence after Boston harbor turned political. Hummingbirds read the red blooms differently, as a summer signal of nectar. Its meaning is generous exchange.

  • Compassion — Its use in healing teas and its shared heritage between Native Americans and settlers symbolize generous care
  • Independence — As the patriotic tea of the American Revolution, it represents self-reliance and liberty

Where the Name Comes From

The name Scarlet Beebalm describes its bee-attracting flowers. Monarda honours Nicolás Monardes, a 16th-century Spanish botanist who documented New World plants; 'didyma' means 'in pairs', referring to the paired stamens.
