Amaryllidaceae. Petticoat daffodil, selected or observed for the increased size and vigor of its flowers compared to the type. Its origin is Iberian, like the species, and it is today mainly known in cultivation, where it is widely spread in rock gardens and specialized bulb collections.
It reaches 15 to 20 cm in height, sometimes a little more, and is distinguished mainly by a particularly ample and well-opened funnel-shaped crown, of a bright and sustained golden yellow, noticeably wider than in ordinary wild forms. The tepals remain narrow and spread around this dominant crown. The foliage is filiform, upright, medium green.
In its natural habitat, the species blooms from February to April. In cultivation, this variety generally blooms in March-April under temperate climates.
It is considered by the Alpine Garden Society as one of the most reliable and generous forms of the bulbocodium group in gardens. It requires well-drained soil, slightly acidic to neutral, in full sun, with a relatively dry summer rest respected. It naturalizes easily in poor lawns mowed late.
