Oxeye daisy is a perennial that can reach from 1-3 ft. (0.3-1 m) in height. A single plant can produce from 1-40 flowering stems. Leaves are 1-4 in. (2.5-10 cm) long, toothed (or lobed) and decrease in size closer to the apex of the stem. Basal leaves are spoon-shaped and petiolate. Flowering occurs all summer, when daisy-like flower heads develop. Each flower head can produce up to 200 flat seeds that are 0.08 in. (2 mm) long. Oxeye daisy is native to Europe and was introduced into the United States as an ornamental in the 1800s. The plants have been shown to carry several crop diseases. Oxeye daisy can thrive in a wide variety of soil types and can grow in sun to partial shade.
