What is Coreopsis tinctoria

Birth flowers for Jul 26

Coreopsis tinctoria, commonly known in Japanese as Harushagiku ("spring-wheel chrysanthemum"), is an annual naturalized plant of the family Asteraceae, native to the central regions of North America.
It is also called Janomegiku ("snake-eye chrysanthemum") or Janomesou ("snake-eye herb") in Japanese, and known in English as Indian blanket or plains coreopsis.
It was introduced to Japan in the early Meiji period.
A representative cultivar has yellow-tipped petals with an inner reddish-orange coloration.
The plant is highly vigorous, easily sprouting from fallen seeds, and has naturalized in the wild.
It blooms almost year-round except during harsh climatic conditions, but when sown in autumn, it typically flowers from June to August.

The plant grows to a height of 60–80 cm, though dwarf varieties around 30 cm also exist.
The leaves are narrow, pinnately compound, and arranged oppositely.
From June to August, it produces 3–4 cm wide flowers.
Some cultivars have yellow-tipped ray florets with reddish-orange centers, while others are entirely yellow or dark reddish-brown.
There are also dwarf and double-flowered varieties.
After flowering, the fruit resembles the shape of a bedbug (cimicid).
It is commonly used in flower beds, planters, potted displays, and as cut flowers.

■ Origin of the Name
The genus name Coreopsis derives from the Greek words koris (meaning "bedbug") and opsis ("resembling"), referring to the seed shape that resembles a bedbug.
The species epithet tinctoria is from Latin, meaning “used for dyeing,” based on its historical use as a dye plant.
The Japanese name Harushagiku ("spring-wheel chrysanthemum") refers to the flower blooming in spring, shaped like a wheel, and belonging to the chrysanthemum (Asteraceae) family.
The alternative Japanese names Janomegiku and Janomesou mean "snake-eye chrysanthemum/herb," referring to the flower's central pattern that resembles a snake’s eye.
