There are several native species of the 

 Clematis, and some of the species have been 

 brought sufficiently under cultivation to develop 

 a tendency to vary widely. Nearly all are rapid 

 climbers, and produce beautiful flowers in great 

 abundance. In addition some have feathery seed 

 pods that are scarcely less attractive arid inter-

 ing an artistic contrast with the foliage for a 

 considerable period. So all in all the clematis 

 must be ranked among the most beautiful of 

 vines. 



My own work with the members of this class 

 of plants has been largely with the types that are 

 known horticulturally as Jackmanni lanuginosa, 

 These have large blue and white flowers, some- 

 times inclined to red and pink. 



This type has been raised very extensively 

 from the seed for many years, and, by selection, 

 several varieties were produced that bore very

 have exceedingly large broad petals with the
