Lunaire monnaie du pape

Biennial plant of about 80 cm. Superb mauve bloom from March to June. The flowers, in clusters, whose scent is exhaled especially at night, attract butterflies. The fruit is particularly decorative: a flat and rounded silique showing the seeds by transparency. When the two side membranes fall off, only a thin pearly disc remains, widely used in the composition of dry bouquets.
