Arisarum 



( 73) 



Aristolochia 



1'eat and fibrous loam in equal parts, with a little 

 sphagnum moss, some charcoal, and sand, form a 

 good compost. Plenty oC water, except when the 

 plants are at rest, is a necessity. Liquid manure 

 in the growing season is helpful.

ARISARUM. 



Half-hardy herbaceous plants (onL Aroidese) of 

 little garden value, allied to Arisicma. They are 

 propagated by division of the rootstock in spring 

 and by seeds. A mixture of equal parts of peat, 

 loam, and sand suits them. 



Principal Species : 



vulgare, 1', My., spathy pur. 



ARISTEA. 



Greenhouse herbaceous perennials (prd. Iridese) 

 of little horticultural value. Propagated by divi- 

 sion of the rootstock in spring and by seeds. 

 Three parts of peat and one part of loam, with 

 sand, suit them.

ARISTOLOCHIA. (I!IRTHWOET.) 



Description. A large genus of stove, greenhouse, 

 or hardy, evergreen or deciduous shrubs (prd. Aris- 

 tolochiacese), climbers for the most part, by means 

 of their twining stems. The plants are remark- 

 able for the curious forms of their flowers, some 

 of which are large and very handsome, but as a 

 rule unpleasantly scented. The climbers make 

 capital pillar or rafter plants, and from the pen- 

 dulous habit of their flowers they need such a 

 position to display them to advantage. Sipho, the 

 Dutchman's Pipe, is a handsome hardy climber, 

 planted chiefly for its foliage. 



Propagation. By cuttings of the young shoots, 

 about ti" long, taken off with a heel of the old wood 

 and inserted in heat under a bell-glass. 



Soil. Two-thirds loam, one-third well-rotted 

 manure and sand. 



Other Cultural Points. As a rule, Aristolochias 

 do best when planted out, although they may be. 

 grown in pots. Good drainage is essential, as they 

 require plentiful supplies of water less in winter 

 with occasional doses of liquid cow manure in 

 the growing season. The growths should not be 

 trained tightly to the roof, bat allowed to hang. 

 In most cases the flowers are borne upon the old 

 wood, but in ringens they are produced upon the 

 young shoots ; the pruning must vary accordingly. 

 The temperature should not be allowed to fall below 

 58", even in winter, for the stove forms. Mealy bug 

 is I lie only insect pest that gives much trouble.
