The oxeye daisy is a typical meadow flower, growing in a variety of plant communities such as dry fields, meadows, but also under scrubs, open-canopy forests and waste places. It thrives in a wide range of conditions and prefers heavy and damp soils. It was introduced in parts of North America, Australia and New Zealand, where it is now a common weed displacing native plant species in some areas. It is difficult to control or eradicate, since a new plant can regenerate from rhizome fragments.
