Appearance

The plant grows to a height of 20–50 centimetres , sometimes exceeding 80 centimetres , and has white or yellow flowers with a purple centre. In the deeply pigmented centre of the flower, the surface features striations, which have been the subject of controversy about whether they act as a diffraction grating, creating iridescence.

The pollinated but unripe seedpods look like oriental paper lanterns, less than an inch across, pale green with purple highlights.

Distribution

It has spread throughout southern Europe both as a weed and cultivated as a garden plant. It has been introduced to the United States as an ornamental where it has become naturalized as a weed of cropland and vacant land, particularly on disturbed ground.
