The popular summer-flowering kind {J. officinale) has pure white 

 fragrant flowers, which are borne freely. J. o. affine (Fig. 294) 

 is a sturdy grower, with large flowers produced in terminal clusters, 

 and may be considered an improvement on the type. The 

 Italian Yellow Jasmine (J. humile) is a pretty summer-flowering 

 kind, with deep golden-yellow flowers. Aristolochia Sipho (Fig. 

 295) is a vigorous climber, and requires plenty of head-room ; 

 its large overlapping heart-shaped leaves are extremely orna- 

 mental, while its yellowish pipe-like flowers, streaked with purple, 

 are curious. For hiding unsightly objects, covering old ruins, 

 arches, &c, it is well adapted. Bignonia capreolata succeeds 

 admirably on a warm wall, 

 and if planted in rich soil 

 with good drainage its 

 reddish yellow tubular- 

 shaped flowers are borne 

 liberally. Tecoma radicans 

 grows freely and attaches 

 itself to walls, &c, by 

 means of its aerial roots. 

 Its trumpet-shaped bright 

 red flowers are produced 

 in clusters at the apex of 

 the summer shoots. T. 

 {Bignonia) grandiftora is 

 a very ornamental quick- 

 growing climber. Its deep 

 orange red drooping 

 flowers are larger than 

 those of T. radicans, 

 and produced more freely. 

 It delights in a rich soil. 



Periploca grceca is a rapid 

 climber, with lanceolate 

 deep glossy green leaves, 

 and great clusters of 

 purplish-brown flowers. It thrives in all soils, and is suitable 

 for covering arbours, trellises, &c. 



The green and variegated Box Thorns (Lycium barbarum and 

 L. b. variegatum) are slender ornamental climbers of free growth, 

 succeeding well in sandy soil. Abelia triflora deserves a place 

 on a wall, and should not be planted in the shrubbery unless 

 the position be very favourable, as it is apt to get injured in 

 severe winters. East winds are very harmful to it. It thrives 

 in any well-drained soil. Plagianthus Lyalli, a rare and beautiful 

 New Zealand shrub, deserves a place against a wall. It belongs 

 to the Mallow family, and in early summer bears clusters of 

 pure white flowers with rich yellow anthers. Ordinary soil suits
