20 PRESENT-DAY GARDENING 



surprising what can be done in this way with the aid of a 

 threepenny packet of seeds and a little imagination. The 

 Canary Creeper ( T. aduncum) is of the same quality, except 

 that it has small flowers and is less robust. This is the 

 place to call attention to the claims of T. speciosum, the 

 pride of some gardeners, the despair of others. T. pen- 

 taphyllum and T. tuberosum also are not without attractions. 

 The three last-named species are, of course, perennial, 

 though their stems are annual. If there is one annual 

 climber which has received the full share of popular favour 

 it is the Sweet Pea (Lathyrus odoratus), but the beautiful 

 perennial species of the genus might well be more in 

 evidence in gardens in every class. Calystegia, Convol- 

 vulus, some of the gourds (see separate chapter), and 

 Lophospermum deserve to be included here. The merits of 

 the Hop also should not be overlooked. Gardeners are 

 too ready to relegate to a back place or pitch out altogether 

 plants whose associations are not strictly horticultural. 

 The Japanese Hop (Humulus japonicus) is a quick growing 

 annual with handsome foliage and large panicles of feathery 

 flowers, which have a rather unpleasant odour. It likes 

 a sunny position, and if the seeds are sown in April it will 

 romp away. 



A list of the genera which furnish the best hardy 

 climbers is here given. For particulars as to species and 

 treatment the descriptive list given under Chapter XV 

 should be consulted.
