298 GARDENING FOR BEGINNERS 



flowering plants by autumn. To this class belong : Gloire de Lorraine, 

 pink ; Turnford Hall, blush ; Glory of Cincinnati, rose ; Elatior, rosy- 

 carmine ; Emily Clibran, orange-salmon ; John Heal, carmine-rose ; 

 Mrs. Clibran, soft pink ; Mrs. Heal, carmine-scarlet ; and Winter Glow, 

 fiery red. 



Bermuda Butter-cup. See Oxalis cemua. 



Blue Gum. See Eucalyptus globulus. 



Boronia. This is a class of hard wooded plants, natives of Australia, 

 and needing much the same treatment as that recommended for the 

 Indian Azalea. The best Boronias are : B. elatior, rosy-red ; B. hetero- 

 phylla, carmine, a very pretty flower ; and B. megastigma, with small, 

 powerfully and sweetly-scented, brownish-yellow, bell-shaped flowers. 

 All form neat little bushes, and all flower in the spring. 



Bottle Brush Plant. See Callistemon salignus. 



Bouvardia. A popular class of greenhouse shrubs that may be 

 propagated from cuttings of the young shoots in the spring after the 

 manner of a Fuchsia, grown on during the summer, and will flower in 

 the autumn and winter. Their neat clusters of wax-like flowers are in 

 great favour for button-holes and similar purposes. The pure white 

 B. Humboldti corymbiflora has deliciously fragrant blossoms. Others 

 are : Hogarth, scarlet ; Mrs. Green, salmon ; President Cleveland, 

 brilliant scarlet ; Queen of Roses, pink ; and Vreelandi, white. Alfred 

 Neuner, white ; President Garfield, pink ; and Hogarth fl. pi., have 

 double blossoms. Soil : loam, leaf-soil, decayed cow-manure, and sand. 



Browallia. An easily grown free-flowering class of plants, the best 

 of which are : data, deep blue ; speciosa, bluish-violet ; and viscosa, deep 

 blue, white eye. Ordinary potting-soil. 



Calceolaria. The showiest and most popular Calceolarias, or 

 Slipperworts, as they are sometimes called, are known as " herbaceous," 

 in which the large, inflated pouches, suggesting in shape a fisherman's 

 basket, are richly and quaintly coloured* Herbaceous Calceolarias are 

 raised from seeds, the best time of the year to sow being about mid- 

 summer, and the young plants so obtained will flower during the follow- 

 ing spring. The seeds are very minute, hence they should be sown 

 as advised for such seeds mentioned on p. 287. When the young 

 plants are large enough to handle prick them off into pots or pans, 

 and when sufficiently advanced transfer singly to small pots. A 

 mixture of equal parts of loam and leaf-mould with a little sand will suit 

 them well for the first potting, after which the amount of loam should 

 be increased. The young plants must be kept in a light, airy position 

 to prevent a weakly growth. Pots six inches in diameter are suitable 

 to flower the plants in, and the strongest may be put in their flower- 

 ing pots by the end of the summer, while the smallest should be left 

 until early in March, when they will form a succession. In all stages 

 aphides or green-fly must be especially guarded against, as they soon ruin 

 the plants, but are easily kept down by vaporising. The varieties with 

 smaller flowers, generally yellow, but sometimes reddish, are of a more 

 woody texture than the herbaceous kinds, and can be struck from cuttings
