Nigella 1

Also called love-in-a-mist, nigella has fine, airy foliage that frames its multilayered, soft blue flowers. And after the petals drop, the plant still looks attractive, thanks to its long-lasting seed pods that resemble tiny fairy lanterns. This easy-to-grow annual works especially well in a cottage garden design, where it can be allowed to reseed itself and help fill open spots in the garden.
