LIST OF FLOWERS 



The best known varieties are N. Damascena and N. Hispanica, in 

 both of which there are several colours — white, blue and purple. 

 Seed should be sown in March in light soil and in the place where the 

 plants are intended to bloom, as the seedlings often do not bear 

 transplanting. 



NOLAN A. A hardy annual of which the varieties N. atriplici- 

 folia and N. prostrata are two of the best. Their trailing growth and 

 slender stems render them well suited for the Rock Garden, and their 

 bell-like blue or violet flowers are very showy. They like a warm, 

 sunny situation and a light soU. Seed should be sown in March 

 and the seedlings well thinned out, not transplanted. 



NYCTERINIA. A pretty half-hardy annual growing in tufts 

 some few inches high and bearing masses of white or blue blossoms 

 in late autumn. N. capensis and N. selaginoides are both good 

 varieties and should be sown in March in heat and planted out in 

 May. 



OENOTHERA. The common name of Evening Primrose is a 

 misnomer in this case, for the blossoms in most kinds are weU open 

 during the day. The genus includes a great variety of perennials, 

 biennials and annuals, and the large kinds, from their free and bold 

 growth, are well suited for the Wild Garden, sowing themselves 

 readUy and only requiring to be confined to their own area in bold 

 groups. Of this kind (E. fruticosa and its varieties are excellent 

 examples, growing from 2 to 3 feet high and bearing a profusion of 

 showy yellow blossoms. (E. missouriensis is more suited for the 

 herbaceous border; it has pendant stems of downy appearance and 

 fine large flowers of bright yellow; it thrives best in a light, warm soil 

 and opens in the evening. (E. triloba is a hardy annual of dwarf 

 growth, and to this class belong (E. Drummondi and Veitchiana, 

 though the last named is better treated as half-hardy. Among the 

 tall and vigorous kinds is (E. Lamar ckiana, an erect and stately 

 biennial growing to a height of 4 feet and bearing magnificent yellow 

 flowers often 4 or 5 inches in diameter, while for the Rock Garden 

 there is (E. taraxacifolia with trailing stems and flowers of pure white 

 which become tinted with a delicate pink as they mature. 



OMPHALODES. A group of dwarf plants well suited for the 

 Rock Garden and of which 0. linifolia is the best known, a hardy 

 annual with silvery leaves and pure white flowers, content with any 

 ordinary soil and often sowing itself. 0. lucilice is also hardy but 

 must have a well-drained soil, though it delights in moisture if not
