"PLANTS GROWN FOR THEIR SCENT 8 1 



propagated annually — by means of cuttings of the shoots 

 of the previous year taken off at a joint and inserted in 

 sandy soil in March or April. They should be potted when 

 rooted, "stopped'' once or twice, and induced to grow 

 strongly by means of plenty of water and occasional doses 

 of liquid manure. Towards the end of the season, when 

 growth slackens, they require drier conditions, and after 

 the leaves fall the soil should be only slightly moist. As 

 soon as the new grow^th starts in spring they should be cut 

 back to make them bushy. 



Bouvardia. — See p. 69. 



Calycanthus (Allspice). — The two- best species are 

 C. floridus and C. occidentalis. Both are deciduous, the 

 flowers purple or red. They require the ordinary treatment 

 for shrubs in pots. Pruning is not recommended unless it 

 is necessary to remove a straggling shoot. 



Carnation. — See p. 70. 



Chimonanthus fragrans. — See p. 72. 



Choisya ternata. — An evergreen shrub with white 

 flowers in July. It is nearly hardy, and in the south can 

 be grown outside in a sheltered corner. When in a pot, 

 it should be put out after flowering to ripen its wood. 

 Cuttings can be rooted in spring, but except for this purpose 

 it should not be pruned. 



Convallaria majalis (Lily-of-the-Valley). — The name 

 suggests the requirements of this charming plant, for in 

 valleys we expect shade and shelter, abundant moisture, and 

 rich soil. For pots, if crowns have to be purchased, those 

 that are three years old should be ordered. If they are only 

 two years old they will flower poorly, and if one year, not at 

 all. When clumps are lifted from the open ground the 

 largest and plumpest crowns should be picked out for use. 

 They should be planted rather closely from autumn until 

 spring, according to the time at which they are wanted to 

 flower, the tips rather above the surface, and covered with 

 moss or fibre to exclude the light. It is a good plan to 

 pack the pots in a box lined with moss. If the box is 

 supported on bricks placed on the heated pipes in a green-
