Physical characteristics of crown daisy
Crown daisy or garland chrysanthemum (Chrysanthemum coronarium = Glebionis coronaria) is an annual, robust plant, with erect and highly branched stems, between 80-100cm. tall.
The leaves are bipinnatifid, sessile (without petiole), alternate and with toothed margins.
The inflorescence of this plant is called flower head, and is typical of composite plants. In botany it is called capitulum. This type of inflorescence is composed of 60-150 tiny yellow flowers.
The chrysanthemum has large flower heads, between 2 and 7cm. in diameter, solitary and terminal.
Both the disc floret and the ligules (petals) are white or golden yellow, with the base always yellow. This flower often surprises because it can have two colors in the petals: yellow petals at the base and white at the ends.
It blooms at the end of spring.
The fruit of the plant is an indehiscent achene without pappus. Inside, there is the seed of the plant.

Components of crown daisy
- The young leaves are a good source of vitamin C and beta-carotene.
- Terpenes
- Phytosterols: campesterol. Scientific studies have isolated this component of crown daisy to treat cancer. Campesterol is believed to prevent the formation of new blood vessels that supply the tumor, thus preventing its growth. This property is known as angiogenesis. Its anti-cancer properties are currently still being studied.
- Flavonoids: apigenin, luteolin, kaempferol, quercetin.
- Flavone glycosides: narnigenin glucoside, apigenin glucoside, luteolin glucoside, kaempferol glucoside, quercetin glucoside.
- Sesquiterpene lactones: They have demonstrated anti-cancer activity in scientific studies.
- Anthraquinones
