Fennel Flower (Nigella)
Hardy annuals of the Crowfoot family, all curious and pretty with feathery Fennel-like foliage and bluish or yellowish blossoms. N. sativa, N. orientalis, N. damascena (Devil-in-a-Bush), and N. hispanica are the kinds cultivated, N. hispanica being the prettiest, growing about 1 foot high, and with showy blue flowers from July onwards. There is a white variety and a variety with deep purple blossoms. All the Nigellas should be sown in March, in light warm soil in the open border. They should be sown in the place which they are to occupy, as they do not succeed so well if transplanted. If sown in autumn, the seedlings often survive the winter and flower early and well.
