CLEMATIS 49 



hybridiser, he can if he wishes ring all sorts of changes 

 with them. The best of the new introductions are : 



C. montana rubens : Flowers claret-coloured, produced in May. 



C. tangutica : Yellow-flowered. Often in bloom in November. 



C. Meyeniana: Flowers white, in large, loose panicles. A 

 robust evergreen. 



C. Armandii (see Plate VII) : A tall climber, evergreen, with 

 large bold cymes of white, Anemone-like flowers. 



C. Dennisce (Sanderi): The Australian form of C. indivisa, 

 evergreen, the long shoots crowded with axillary panicles of white 

 star-like flowers, the red and yellow stamens forming a conspicuous 

 brush-like cluster in the centre of each star. 



C. Wilsonii: A long-stalked, large, white-flowered variety of the 

 polymorphic C. montana^ flowering in late autumn. 



C. Sieboldii (see Plate IX) : A new Clematis with neatly formed 

 white perianth of six segments, showing off finely a central mass of 

 purple, linear, modified, barren stamens. Flowers 3^ inches' 

 diameter. 



The cultural requirements of Clematis may be called 

 quite ordinary. They prefer a loamy soil, light rather 

 than heavy, and they like lime or chalk mixed with it in 

 the proportion of a spadeful to a barrowload. They also 

 enjoy an annual mulch with rotten farmyard manure, 

 which should be applied in winter. The shoots are self- 

 supporting, but they require a little arranging at the start. 

 Where there is plenty of room the less pruning they get 

 the better ; all that is needed being a kind of combing out 

 to get rid of brash and prevent overcrowding. This should 

 be done in early spring before new growth starts. In some 

 positions, however, a decided pruning may be necessary, 

 and some varieties in some positions require to be annually 

 close pruned ; this should be done in spring. The Jack- 

 manii race is the hardiest and most useful of all because
