Perennial of the Asteraceae family, this taxon is a horticultural hybrid of garden origin, resulting from the cross between Leucanthemum maximum, from the Pyrenees, and Leucanthemum lacustre, from Portugal. It does not exist in the wild and is only known in cultivation, where it has given rise to many cultivars selected since the late 19th century.
It forms vigorous and upright clumps, reaching 50 to 80 cm in height, with glossy dark green foliage, spatulate and toothed basal leaves. The capitula, significantly larger than those of the common daisy, bear large well-ordered white ligules around a bright yellow to orange-yellow disc, particularly luminous.
As a garden hybrid, it does not have a natural reference flowering. In cultivation, its flowering extends from June to September, with prolonged generosity if the faded flowers are regularly removed.
Its central disc, a deeper and warmer yellow than that of L. vulgare, gives it a more assertive character. It thrives in ordinary well-drained soil, in full light, and tolerates some drought once established. Regular division of the clumps, every two to three years, maintains the vigor and abundance of flowering.
