blue and white ; and N. gracilis, white and purple, are tender 
species, and best grown in greenhouses during the winter and 
planted out in May for summer decoration only. N. rivularis 
should be planted in spring. Increased by seeds sown in heat 
in March, the seedlings being hardened off in May and planted 
out in June; also by cuttings of the young shoots in spring 
in heat. 
Nigfella (Devil in the Bush; Fennel Flower; Love-in-a- 
mist). — Hardy annuals, with elegant, finely-cut foliage and 
curiously formed flowers. Members of the Buttercup order 
(Ranunculaceae). N. damascena, a native of Asia Minor, 
grows i to 2 ft. high, and bears blue flowers surrounded by 
a quaint mossy fringe. There is a double-flowered variety of 
it called flore pleno, and a white one named alba. N. 
hispanica has deep blue flowers and no fringe ; it grows i to 
2 ft. high, and is a native of Spain. There are white and 
purple varieties of it. Other less grown species are N. 
orientalis, yellow and red ; and N. sativa, blue. These curious 
annuals are easily grown. Sow the seeds thinly in patches 
in sunny borders in March or April, and afterwards thin out 
to 8 or i 2 in. apart. Ordinary soil. 
Nolana (Chilian Bellflower). — Hardy annuals, natives of 
S. America, and members of the Convolvulus order (Convolvu- 
laceae). The few species grown are N. atriplicifolia, blue with 
white centre, shoots trailing ; N. lanceolata, blue, white and 
green, height 6in. ; N. paradoxa, blue, trailing shoots; N. 
prostrata, blue, trailing shoots ; and N. tenella, pale blue, trail- 
ing habit. The trailing species are suitable for sunny rockeries 
and the erect species for a sunny border; ordinary soil. Sow 
seeds in April where required to flower, and thin the seedlings 
out to 6in. or so apart later on. 
CEnothera. (Evening Primrose). — Hardy annuals, bien- 
nials and perennials, belonging to the Fuchsia order (Ona-
