Oxeye daisy, ox-eye daisy
The oxeye daisy is widespread throughout North America, but not a native—it comes from Europe and Asia. In some locales they border on invasive.
Plants: These daisies are 1–2½′ (30–76 cm) high. Stems are hairy near the bottom.
Leaves: Heavily lobed dark green leaves. Lower leaves are 1½–6 ⨉ ⅜–1¾″ (4–15 ⨉ 1–5 cm) in size, roughly oval, with up to 15 irregular teeth or lobes. Upper leaves are progressively smaller, sessile, and deeply toothed.
Flowers: Like other members of the aster family, daisies are composite flowers, with a yellow central disc composed of disc flowers surrounded by about 20 white “petals,” actually ray flowers. Typically there is a single flowers per stem, 1–2″ (2.5–5 cm) around. The central disc is ¼–½″ (6.3–12 mm) around, and depressed in the middle. Flowers appear from May to October.
Fruits: Achenes are 1/32–⅛″ (1–3 mm) long, with ten ribs.
Habitats: Meadows and fields, under scrub and open-canopy forests, and in disturbed areas.
