ON CLEMATISES 115 



Florida, a white species introduced from Japan, blos- 

 soming in June ; Lanuginosa, a blue June bloomer from 

 China ; Patens, white, a Japanese plant blooming in 

 June ; and Viticella, purple, an August bloomer, are 

 well-known hardy species ; but they are better repre- 

 sented by their varieties than in themselves. The last 

 four have all given their names to sections. 



Jackmanii has also done so, but it is a hybrid. This 

 remarkable Clematis is certainly the most popular of 

 all the large flowered, rich-coloured class, and is familiar 

 to almost every lover of climbing plants. It is beautiful 

 on porches, roofs, trellis-work, pillars, and verandahs, 

 bearing its large violet-blue flowers in great abundance 

 in July and August. It was raised in 1858 by a Woking

 called Hendersoni. The latter was raised in 1835 by 

 crossing the species integrifolia and viticella, and bore 

 purplish-blue flowers. A hybrid called rubro-violacea, 

 with purplish-maroon flowers, came from the same 

 cross ; but although it is a good Clematis, it was over- 

 shadowed from the first by Jackmanii. 



Clematis Jackmanii is one of the most profuse-bloom- 

 ing plants ever grown in a garden. It becomes a mass 

 of bloom in late summer, quite hiding whatever object 

 it may be grown upon. Such a plant, if also hardy and 

 a fast grower and Clematis Jackmanii is both is bound 

 to become a great favourite, because it meets the wants 

 of innumerable gardeners. Suburban as well as country 

 amateurs love Clematis Jackmanii, and town gardeners 

 might succeed with it nearly as well as their rural 

 brethren if they would provide better soil than they 

 generally do, and use the knife with a little more courage. 

 It is very rarely that the natural soil of a suburban
