Growing erect in form, plants grow 1 to 3 feet tall and 1 to 2 feet wide. This herbaceous perennial has broadleaf evergreen foliage that is finely textured. Leaves measure 1 to 5 inches across, toothed and deeply cut, with the longer leaves at the plant’s base. Flowers bloom from May to August, the flattened yellow center disk resembling the eye of an ox. Each flower measures 1 to 3 inches in diameter and has seven to 20 petals. Stems are thin and 1 to 2 feet tall, usually branching to produce two or more flower heads. Showy flowers make good, long-lasting, cut specimens in bouquets or on their own in vases of water.
Light
Establish in a sunny spot, preferably full sun. It can also grow in part sun or afternoon shade, especially in hot, humid climates.
Soil
Sow seeds in average, well-draining soil. Plants can also grow in drier, sandy soil.
Water
Because the oxeye daisy is drought-tolerant, let the soil dry out between waterings. Seeds, however, should be consistently moist while they sprout. After that, decrease watering to one to two inches per week.
Temperature
Oxeye daisy can survive temperatures as low as 28 degrees Fahrenheit. It needs 130 frost-free days to grow, reproduce, and thrive.
Pruning
To encourage more blooms, deadhead the flowers regularly. To prevent the oxeye daisy from becoming invasive, remove plants before they produce seeds. Be sure to pull plants out by their roots. Since oxeye daisies have a shallow root system, they are easy to pull out completely. Mow any unwanted seedlings before they get too big. Then spread mulch on the ground. This will prevent new seeds from sprouting. You can also use a lawn-safe herbicide dedicated to oxeye daisies.
Propagation
Plants spread by rhizomes and self-seed. Divide them every two or three years or propagate by root cuttings.
How to Grow From Seed
Oxeye daisy can also spread by seeds, which are tufted and dispersed by the wind and in dung. These seeds can be moved with timber, contaminated forage grass, and legume seed, too, and typically remain viable for 20 years (sometimes up to 39 years) in the soil without requiring cold-stratification. If starting seed purposefully, note that seedling germination is most successful with increased light and soil moisture.
Common Pests and Diseases
Keep an eye out for the occasional aphids, mites, and leaf miners. Oxeye daisies are also susceptible to verticillium wilt, leaf spots, and stem rots. Overall, though, they are very hardy and resistant to the challenges of many other common diseases as well as deer and rabbits.
