White to lilac summer flowers are followed by translucent, flattened seed heads. These will remain on the plant well into autumn, or if picked and dried, make excellent additions to dried flower arrangements. Given a sunny or partially shady site with fertile, moist, well-drained soil this charming biennial will happily self-seed. As the flowers are highly-attractive to butterflies and bees, they are perfect for naturalising in a wild garden, meadow, or at the woodland edge.
