warm soil. The following 

 and pretty : 



C AMERICANOS (New 



Jersey Tea}. Though 

 one of the hardiest, this 

 thrives best against a 

 wall, and in a dry porous 

 soil ; the flowers, which 

 come in succession from 

 about the middle of June 

 till August, are white, and 

 numerous. E. America. 

 C. AZUREUS. From 

 the temperate regions of 

 Mexico, where it grows 

 as a straggling bush about 

 10 ft. high. It is one of 

 our prettiest wall shrubs, 

 flowering abundantly in 

 dry sunny situations, the 

 flowers bright blue, from 

 June till September. C. 

 pallidus is a handsome 

 variety, with pale-blue 

 flowers. The result of 

 crossing with this species 

 may be seen in such lovely shrubs as C. Gloire 

 des Versailles, Arnoldii, Lucie Simon, Theodore 

 Froebel, Bertinii, President Reveil, Lucie 

 Moser, and others, all of which have flowers 

 in large plumy clusters, some white, others 

 rose, but mostly of some shade of blue. 



C. DENTATUS is an elegant little evergreen 

 shrub, rarely higher than about 3 ft. The 

 flowers, which appear in May or June, are 

 deep blue, and continue the greater part of the 

 season. 



C. DIVARICATUS grows as a dense broad 

 evergreen bush of about 10 ft. high. It is a 

 free-growing handsome wall plant, flowering 

 from May to autumn, the flowers a bright blue. 

 C. PAPILLOSUS is a pretty species from the 

 mountains of California, where it is a densely 

 branched straggling bush 6 to 10 ft. high. The 

 panicles of pale-blue flowers are borne on long 

 foot-stalks from the sides of the young shoots. 

 Like the other kinds, it loves the protection of 

 a wall, on which it blooms in summer. 



C. RIGIDUS is a sub-evergreen, or in 

 sheltered places an evergreen, rarely exceeding 

 6 ft. in height, the branches stiff and wiry ; 

 the flowers, in clusters on the sides of the 

 young shoots, are deep purple, in April and 

 May. 



C. VEITCHIANUS is one of the best kinds, 

 the flowers of a rich deep blue, in dense 

 clusters at the ends of leafy branches. G. 



C. VERRUCOSUS forms a thickly branched 

 evergreen bush about 6 ft. high. As a wall 

 plant it is of free growth, and has a good effect, 

 the flowers coming in May and during the 

 summer months, borne in corymbs along the 

 whole length of the young branches, often so 

 profusely as to hide the foliage. 



CEDRELA. C. sinensis is somewhat 

 similar to the "Tree of Heaven" (Ailan- 

 thus glandulosd). but this Chinese tree is 

 much more uncommon in gardens. In 



some places, however, it might be a more 

 suitable tree, for whilst it has much the 

 same character of foliage and habit, it is 

 not so rampant a grower. The Ailanthus 

 is often somewhat of a nuisance through 

 its habit "of sending up root-suckers at 

 long distances from the stem. The 

 Cedrela has not this habit, although it 

 can, like the Ailanthus, be increased by 

 root-cuttings. The largest specimens 

 I have seen are about 30 ft. high. The 

 tree is chiefly noteworthy for the large 

 pinnate leaves it bears, these being, indeed, 

 amongst the most striking to be met with 

 in the large or medium-sized trees hardy 

 in this country. C. sinensis, which is the 



Catananche coerulea. 



only one hardy in Britain, was for a long- 

 time known as Ailanthus flavescens. It 

 has small yellowish flowers arranged in 

 great numbers in pendent clusters said 

 to be agreeably scented. Among the 

 trees of the genus there are some remark- 

 able for their uses, but they are tropical, 

 and we have no object in giving any 

 particulars of them in this book. As far 

 as we know C. sinensis it promises to 

 be a graceful lawn tree, but has not been 

 long enough in the country yet to speak 

 with certainty of its hardiness, although 

 we see it flourishing in unlikely places. 



W. J. B. 



CEDRONELLA (Balm of Gilead] is a 

 distinct half-bushy herb of the Sage order, 

 C. triphylla having leaves with a pun- 

 gent but grateful odour, in our coun- 

 try -2\ to 4 ft. high, varying much 

 according to soil, and not quite hardy, 

 but living out-of-doors most winters if in 

 dry free soil and planted against walls.
