HARDY CLIMBING SHRUBS 77 



common Ivy (Hedera Helix), of which there are many 

 distinct and striking forms, should be cultivated. 

 This plant ranges through Europe, northern Africa 

 and northern Asia to Japan and is extremely poly- 

 morphic. The varieties amurensis, chrysocarpa, col- 

 chica, crenata, deltoidea, rhombea and canariensis 

 (Irish Ivy) are among the best. There are also 

 many variegated forms and those who like such plants 

 may indulge their fancy. The new Clematis Armandi 

 from central China with white flowers, and its form 

 Farquhariana with pink flowers, should be especially 

 useful in the south and on the Pacific Slope. The 

 three-foliolate leaves are dark polished green and the 

 flowers each two to three inches across are freely 

 produced in large axillary clusters. For gardens 

 situated where a genial climate prevails I count this 

 Clematis among the most desirable and beautiful 

 of plants I have been privileged to introduce into cul- 

 tivation.
