What does calliopsis mean?
Calliopsis is a genus of flowering plants in the daisy family (Asteraceae), native to North America and widely grown as cheerful annuals for their golden, daisy-like blossoms — most familiarly Coreopsis tinctoria, whose yellow petals are often marked with deep maroon at the base. Commonly called tickseed because of its small, tick-shaped seeds, calliopsis has long been a favorite of seed catalogs and cottage gardens, prized for being easy to grow, quick to bloom, and attractive to pollinators. The name derives from Greek kalos ('beautiful') and opsis ('appearance'), literally 'beautiful sight.' Although botanical taxonomy has largely absorbed Calliopsis into the broader genus Coreopsis, gardeners still use the old name affectionately, and it survives in heritage seed lists and wildflower mixes across North America.
nounA plant of the genus Calliopsis (now often treated as Coreopsis), native to North America and bearing bright yellow or orange-and-maroon daisy-like flowers; also known as tickseed.
- Any flowering plant of the genus Calliopsis/Coreopsis, especially Coreopsis tinctoria, cultivated for its bright daisy-like blooms.
"The roadside meadow was ablaze with calliopsis, its golden blooms glowing against the late-summer grass."
"She scattered calliopsis seeds along the sunny border, knowing they would bloom within weeks."
"Victorian seed catalogs listed calliopsis among the easiest annuals for cutting gardens."
As a scientific generic name, calliopsis is typically left unchanged when referring to multiple members of the genus; the anglicized plural 'calliopses' occasionally appears in informal gardening writing.
"Several calliopsis bloomed along the fence line all summer."
Its very name means 'beautiful sight' in Greek — a botanist's compliment written straight into the label.

Etymology of calliopsis
The word calliopsis comes from New Latin, formed from the Greek elements kalos, meaning 'beautiful,' and opsis, meaning 'appearance' or 'sight' — together yielding 'a beautiful sight.' The Greek root kal- also underlies words like calligraphy and kaleidoscope, while opsis appears in synopsis and autopsy. The genus was named by botanists in the early nineteenth century, and later taxonomic work folded it into Coreopsis, though the name persists in horticulture.
How calliopsis is actually used
Chiefly used in horticultural and gardening contexts; the botanical classification has largely merged Calliopsis into the genus Coreopsis, so modern references often use 'tickseed' or 'coreopsis' instead. The word carries a pleasantly old-fashioned, catalog-garden connotation.
Easily confused with calliopsis
Cosmos is a different genus of similar-looking daisy-family flowers; calliopsis typically has yellow or bicolored maroon-and-yellow ray florets and is also called tickseed.
