it reaches to a height of about twelve feet, and 

 flowers in late summer ; perennial. 



C. montana, flowers white, about four inches 

 across, in great profusion in June; a rampant 

 climber; perennial. 



G. flammula, and C. paniculata, are both 

 charming perennial climbers for covering rough 

 fences, or arches ; growing in great masses, with 

 profusion of tiny white flowers, in autumn ; both 

 are very fragrant, and in appearance rather like 

 the wild Clematis. 



C. Jackmani has large purple flowers in July 

 and August ; this and the other large-flowered 

 Clematis are beautiful, but must be grown with 

 other things to support them, as they have not 

 foliage enough to look well quite alone. The kinds 

 called Clematis of the Patens-type, and Florida- 

 type, bear flowers in the spring on the old wood, 

 and must not be cut back, but the Viticella-type, 

 Launginosa-type and Jaekmani-type bear flowers 

 on the summer shoots, and may be cut right back 

 to two or three feet high, after flowering, if you 

 wish to make them flower near the ground ; 

 "Nellie Moser" is a very beautiful variety of the 

 Launginosa type.
