What is the common name of Leucanthemum?

Leucanthemum is commonly known as "Daisy." This name refers to a group of flowering plants that are recognized for their characteristic white petals and yellow centers, which resemble the profuse and cheerful blooms often associated with daisies.

The genus Leucanthemum includes several species, most notably the garden daisy (Leucanthemum vulgare), which is widely cultivated for its ornamental value in gardens and landscapes. Daisies are well-loved for their simple, classic appearance and their ability to thrive in various conditions.

The other options—chamomile, bluebell, and buttercup—refer to different plants with distinct characteristics and belong to different genera. Chamomile is known for its use in herbal teas, bluebells are recognized for their bell-shaped flowers often found in woodlands, and buttercups are known for their bright yellow flowers that typically bloom in meadows. These plants have their unique traits and uses, which differentiate them from Leucanthemum.
