A widespread plant native to Europe and Asia. Plant was introduced to Australia, New Zealand and North America. It likes a temperate climate where the average annual rainfall exceeds 750mm (30 inches). Favouring soils that are heavy and moist, often grows in neglected pastures and along roadsides. Being a typical grassland perennial wildflower, it can be found growing in a variety of habitats. Meadows, fields, under scrub and open-canopy forests, edge of woodlands is also an ideal habitat for the Oxeye Daisy.
A mature plant can produce up to 26,000 seeds, it can also multiply itself by its under-ground root system which continuously puts out lateral shoots to spread away from the mature plant. By spreading itself this way, it produces a negative effect to other native plants growing close by.
In over 40 countries it is considered to be an invasive species, it is also detrimental in meadows where livestock are to graze especially cattle.
This plant was top-raked for pollen production per flower head, in a U.K. study of meadow flowers.
