ARCHES, PERGOLAS, PILLARS, AND STUMPS 273 



The most useful of the Jasmines is certainly nudiflorum, which 

 produces its yellow flowers during mild spells throughout the 

 whole of the winter, blooming in advance of the leaves. It is 

 quite hardy. There is a large form of the common, white, summer- 

 flowering Jasmine called Jasminum qfficinale affine ; and there is 

 a variety with golden leaves. 



The following are other hardy perennial plants suitable for 

 growing up poles : Aristolochia Sipho (Dutchman's Pipe), Periploca 

 graeca, Polygonum Baldschuanicum (which produces glorious fleecy 

 masses of bloom in summer and autumn), Tropaeolums of various 

 sorts, and the large-leaved Vines, such as Vitis Coignetiae. Cobaea 

 scandens (flowering in summer from seed sown in spring under 

 glass), Eccremocarpus scaber (easily raised from seed), and the 

 Passion Flowers (Passtfloras) are not quite hardy, but may be 

 used. 



Among Annuals that may be sown out of doors are the Con- 

 volvulus and the Nasturtium ; and of those best raised under glass 

 and planted out in May may be named Canary Creeper, Mina 

 lobata, Ornamental Gourds, and Maurandya. For fuller notes on 

 these, see the chapter on Annuals. 



Semi-climbing Roses like Alister Stella Gray and Grtiss an 

 Teplitz are good for large stumps. Tall Nasturtiums may also 

 be sown at the foot of stumps, or Canary Creeper trails led 

 over them. The small-leaved Ivies (see chapter on Walls) are 

 also good for the purpose.
