382 MANUAL OF GARDENING 



seasons are not long enough for seed plants to give good bloom. Cut- 

 tings may be made before danger of frost and wintered in the house, 

 or the plants may be grown from seed sown in January or February. 

 Seeds should be scalded or filed just before sowing. 



The true moon-flower is Ipomcea Bona- N ox, white-flowered; but 

 there are other kinds that go under this name. This grows 20 to 30 

 feet where the seasons are long enough. 



Narcissus (see Bulbs, p. 281). — Daffodils, jonquils, and the poet's 

 narcissus all belong to this group, and many of them are perfectly 

 hardy. The polyanthus section, which includes the Paper- white nar- 

 cissus and sacred lily or Chinese joss-flower, are not hardy except with 

 unusually good protection, and are, therefore, most suitable for grow- 

 ing indoors. 



It is common to allow the hardy sorts to take care of themselves 

 when once planted. This they will do, but much more satisfactory re- 

 sults will be had by lifting and dividing the clumps every three or four 

 years. A single bulb in a few years forms a large clump. In this con- 

 dition the bulbs are not properly nourished, and consequently do not 

 flower well. Lifting is preferably done in August or September, when 

 the foliage has died down and the bulbs are ripe. 



The narcissi are well suited to partially shaded places, and will 

 grow and please wherever good taste may place them. They should 

 be freely used, as they are fragrant, bright of color, and easily managed — 

 growing among shrubbery, trees, and in places where other flowers 

 would refuse to grow. They should be planted in clumps or masses, 

 in September or October, setting the bulbs 5 to 8 inches apart, ac- 

 cording to size, and 3 or 4 inches deep. 



Several species and numberless varieties, both double and single, 

 are grown. A few good types only can be mentioned (Fig. 260) : —

 rivatives) .
