DESCRIPTIVE LIST OP FLOWERS. 165 



It has the reputation of being more tender, requiring 

 greater heat to bring it to perfection. With me, it stood 

 near the other species two winters, with the same protec- 

 tion. The flowers are produced only on the old wood ; it 

 is necessary, therefore, to lay down, and cover the growth 

 of the season, to insure bloom the next year. The flow- 

 ers are four or five inches in diameter, of a rich blue, in 

 July ; a climber, like the last, but not of so robust growth. 

 C. Sieboldii is certainly the most showy of the genus, but 

 since the first edition of my "Book of Flowers" was 

 published, I have found by experience, that it is not so 

 hardy as C. azurea grandiflora, which has proved quite 

 hardy when the vines are laid down, producing a profusion 

 of its rich blue flowers. Wherever a lattice is mentioned 

 by the Poets, it is expected the Clematis will run over it : 



" In the calmness of a cloudless eve, 

 How gently dies a long, long summer's day, 

 O'er yon broad woods, as loth to take its leave, 

 It sheds at parting its most lovely ray, 

 And golden lights o'er all the landscape play, 

 And languid zephyrs waft their rich perfume 

 "Where the wide lattice gives them open way, 

 And breathe a freshness round the twilight room, 

 From Jasmine, Clematis, and yellow-blossomed broom." 



All the climbing species are shrubby, and if laid down and 

 covered with earth late in autumn, will flower much bet- 

 ter than the plants exposed in winter. 



C cirrhosa is a beautiful white-flowered, sweet-scented 

 species. Besides the species and varieties enumerated, 

 there are many others, esteemed ornamental. 



CLEOME. 



This is an elegant genus of plants, and very curious in 

 their structure. The petals range themselves on the upper 

 side, and the stamens and pistil are protruded a consider-
