BROWALLIA. Annual plants of the 

 Nightshade Order, chiefly Peruvian. B. 

 data has usually been regarded only 

 as a beautiful pot-plant, but it does well in 

 the open air, either in a bed by itself or in 

 large patches with other things. It supplies 

 a shade of colour difficult to obtain, 

 and is useful to cut from. Sow the 

 seed in March, prick off the young 

 plants when large enough to handle, grow 

 them on till they are strong, and plant out 

 in May. There is a white variety equally 

 useful. B. Roezli is a dense compact 

 bush, 16 to 20 in. high, with . shining 

 green leaves. The flowers are of a 

 delicate azure blue, or are white with 

 a yellow tube, and are unusually large for 

 the genus. They come in uninterrupted 

 succession from spring till autumn. 

 Rocky Mountains. 



Brugmansia. See DATURA. 



BRUCKENTHALIA SPICULCEFO- 

 LIA. A pretty little heath-like plant 

 with pale purple flowers under i ft. high. 

 It is a plant for the rock-garden in free 

 peaty soils. S.E. Europe. 



BRYANTHUS. A rare and interest- 

 ing group of northern and Arctic heath- 

 like plants, few of which are in cultiva- 

 tion. B. erectus is a dwarf evergreen 

 Ericaceous bush, from 8 in. to i ft. high, 

 bearing pretty pinkish flowers. Said to 

 be a hybrid. In fine peat, it grows well, 

 and is best on the rock-garden or among 

 dwarf alpine shrubs. Among the known 

 kinds are Breiueri, glanduliflorus, gme'lini, 

 all peat and rock-garden plants. Some- 

 times our own beautiful Menziesia ccerula 

 is included under this name. 



BUDDLEIA (Orange Ball Tree\B. 

 globosa is a favourite shrub from Chili, often 

 seen in the southern coast gardens, where 

 it is hardier, and in Ireland ; the flowers, 

 balls of bright yellow, are showy in early 

 summer. It is of rapid growth, and if 

 badly cut down during a severe winter 

 generally grows again in the following 

 summer. B. Colvillei is a tender Hima- 

 layan kind, with bunches of pale rose- 

 coloured flowers. It is a shrub for mild 

 districts only. Other species less satis- 

 factory for open-air culture are B. crispa, 

 B. Lindleyana. B. albiflora is from Central 

 China, with flowers in long spikes. The 

 name, however, is a mistake, as the flowers 

 are mauve (not white). It is a handsome 

 plant, and promises to be hardy and free. 

 B. variabilis, is a native of the mountains 

 of China. It is a large shrub, 8 to 10 or 

 more feet high, variable in foliage, and 

 with flowers densely crowded in globose 

 heads peduncled in the axils of the upper- 

 most leaves, and which vary in colour 



from pink to pale lilac, with an orange 

 throat. Some forms of this are very free 

 and beautiful shrubs. 



BULBOCODIUM (Spring Meadow 

 Saffron). B.vernum is a pretty Liliaceous 

 bulb from 4 to 6 in. high, and one of the 

 earliest of flowers, sending up large rosy 

 purple flower-buds, distinct in colour. 

 The tubular flowers are nearly 4 in. long, 

 and are usually prettiest in the bud state. 

 Associated with very early flowering 

 plants like the Snowflake, Snowdrop, and 

 Greek Anemone, it is welcome in the 

 rock-garden or in warm sunny borders. 

 Easily increased by dividing the bulbs 

 in July or August, and replanting them 

 from 4 in. to 6 in. apart. One other 

 species, B. trigyniim, is sometimes met 

 with in cultivation. Alps of Europe. 



BUPHTHALMUM. B. spedosum is a 

 bold free and showy perennial, hardy, and 



Buphthalmum speciosum. 



growing in any soil, with large heart- 

 shaped leaves in great tufts, and, in 

 summer and autumn, handsome heads ot 

 showy yellow flowers with dark centres. 

 An excellent plant for shrubberies and 

 covering the ground here and there in 

 bold masses, as it grows so close that it 

 keeps the weeds down and in such ways 

 also gives a better effect than in small 

 tufts in the mixed border. Central 

 Europe. Division. Syn. Tdekia spedosa.
