What does althea mean?
Althea is a noun with two principal uses: as a horticultural term for certain flowering plants of the mallow family, and as a female given name of Greek origin. In gardens, especially across the American South, 'althea' most often refers to Hibiscus syriacus, the hardy deciduous shrub better known as the rose of Sharon, prized for its abundant summer blooms in shades of white, pink, lavender, and blue. The name descends from the ancient Greek word for healing, reflecting the medicinal reputation of related mallows such as the marshmallow plant, whose roots were historically used in soothing preparations. Botanically, many plants once grouped under the genus Althaea have been reclassified into Hibiscus and other genera, so the term today functions more as a traditional common name than a strict scientific label. As a personal name, Althea evokes classical mythology and appears in poetry and literature, lending it an air of old-world elegance while remaining distinctive in modern usage.
A flowering plant of the mallow family, especially Hibiscus syriacus (rose of Sharon), cultivated ornamentally for its showy summer blossoms.
"Bees crowded the purple althea blooms outside the kitchen window all August."
In American gardening contexts, 'althea' is nearly synonymous with 'rose of Sharon'; British usage more often favors 'hibiscus' or 'tree mallow' for similar plants.
A female given name of Greek origin, associated with healing and with mythological figures.
"Althea introduced herself quietly, her name echoing lines from an old poem she loved."
Used when referring to multiple plants of this kind; the given-name sense does not take a plural.
"They planted a row of altheas along the fence for late-summer color."
The same Greek root that names this flower — meaning 'to heal' — also gave us the marshmallow plant once used to make real medicinal confections.

Etymology of althea
The word derives ultimately from the ancient Greek ἀλθαία (althaia), associated with the root meaning 'to heal' (ἄλθος), a reference to the medicinal properties attributed to mallow plants. The term entered botanical Latin as Althaea, the genus name assigned to mallows including the marshmallow, and passed into English usage as a common name for these plants. In Greek mythology, Althaea was the mother of Meleager, giving the name additional literary resonance that carried into its use as a female given name in English-speaking countries.
How althea is actually used
As a common noun, 'althea' is primarily a horticultural term used by gardeners, particularly in the southeastern United States where Hibiscus syriacus thrives. As a given name, it carries literary and mythological associations and remains relatively uncommon.
