Leucanthemum is a genus of annuals and perennials that bear daisylike flowers. The genus includes Shasta daisies and the commonly grown bedding plant Leucanthemum paludosum widely known as Chrysanthemum paludosum and also oxeye daisies
Shasta Daisy, Leucanthemum x superbum, is an upright perennial with large white, or sometimes yellow, daisy-like flowers that appear from mid-summer to fall. Shasta daisies are often used in beds and borders.
Leucanthemum paludosum widely known as Chrysanthemum paludosum is a low-growing and spreading summer-blooming annual that grow to 4 inches (10cm) tall. It nearly forms a mat of white daisy flowers and is often used in beds and containers.
Oxeye daisy, Leucanthemum vulgare, is often naturalized in wildflower gardens and meadows. It can grow to 3 feet (.9m) tall and bears 1 to 2 inch wide white daisies with yellow centers.
Nearly all Leucanthemums have deeply lobed, toothed. or scalloped leaves. Flowers are solitary at stem tips. White ray florets, or petals, surround yellow centers of densely packed disk florets.
