Leucanthemum × superbum is native to France and Spain but it can be found growing wild in other parts of the world as an introduced species and sometimes a garden escapee. It is a rhizomatous perennial herb growing 30 to 70 centimetres tall with many large serrated leaves around the base of the stem on winged petioles. There are smaller lance-shaped leaves alternately arranged along the stem. The inflorescence is generally a large, solitary flower head which may exceed 8 centimetres in diameter. It has a fringe of 20 to 30 white ray florets around a centre of many densely packed yellow disc florets.
The flower is similar to the oxeye daisy Leucanthemum vulgare but has larger and more robust blooms. They are characterized by a distinct odour which some find unpleasant.
Leucanthemum × superbum tends to bloom every spring to early autumn in 0.75 m wide clumps. The fruit is a small ribbed achene without a pappus.
