Sometimes a plant's proper name is embedded, if not camouflaged, in its title. Many are tagged in honor of a "plant guy," including:
Fuchsia: Leonhart Fuchs, a 16th-century botanist who wrote a definitive book on using plants for medicinal purposes. (The color fuchsia wasn't coined until 1859.)
Gardenia: No, gardens aren't named after this shrub, nor it after garden. It's named for Dr. Alexander Garden, a Scottish physician and botanist who lived in Charleston, S.C., in the mid-18th century but was banished back to his homeland after siding with the Brits in the Revolutionary War.
Rudbeckia: Two botany professors at Sweden's Uppsala University, Olaf Rudbeck the Younger and Olaf Rudbeck the Elder.
Zinnia: Johann Gottfried Zinn, an 18th-century botanist and anatomist who provided the first detailed anatomy of the human eye.
Other annuals and perennials named after botanists: dahlia (Sweden's Anders Dahl), forsythia (Scotland's William Forsyth), gerbera (Germany's Traugott Gerber), heuchera (Germany's Johann Heinrich von Heucher), lobelia (Belgium's Matthias de Lobel) and magnolia (Pierre Magnol).
The power of myth
Some plant names are based on ancient mythology:
Achillea: Achilles, the Homeric hero who purportedly gave this plant to his soldiers to help stop the bleeding from wounds during the Trojan War.
