"Daisies are often considered weeds because they thrive in inhospitable conditions and are resistant to bugs and even magical pesticides."
Zygmunt Budge, Book of Potions[src]

A daisy is a common European wildflower with white and yellow flowers. Its roots are an ingredient used in the Shrinking Solution and Essence of Daisyroot. Severus Snape kept a bottle of the latter elixir in the Potions Classroom at Hogwarts in 1995. Daisies are also used in the brewing of alcoholic beverages, such as the Daisyroot Draught.

There was a reference to daisies in Ron's unsuccessfully performed colour changing charm in 1991.[1]



The roots of a daisy on a chopping board

The Latin name 'Asteraceae' is derived from the type genus Aster, which is a Greek term, meaning "star".[2] While 'Compositae', an older but still valid name,[3] means composite and refers to the characteristic inflorescence, a special type of pseudanthium found in only a few other angiosperm families. The study of this family is known as synantherology.

In addition, the name daisy is derived from its Old English meaning, dægesege, from dæges eage meaning "day's eye," and this was because the petals open at dawn and close at dusk.
