THE FLOWER GROWER'S GUIDE. 



Eoses for producing the free growth that is essential for the purposes indicated, 

 require to be planted in rich, deep, loamy soil. They make the best progress when cut 

 severely back when they are starting into growth after jjlanting. Subsequent pruning 

 consists in removing old weakly parts, leaving many of the young growth their full 

 length, but shortening same at diiferent heights from near the ground, upwards, or 

 the lower parts of pillars or arches will be bare and unsightly, as represented in the 

 clematis arch on page 120. Eoses are increased by budding, grafting, cuttings, and 

 layering, new varieties being raised from seeds. For cultural details, see the chapter 

 on Eoseries to follow. 



Ivies for Pillars and Arches. 

 For affording close surfaces of green or coloured leaves in the winter no plants 

 equal the green and variegated forms of Hedera helix. There are varieties with a neat 

 clinging habit of growth and sniall leaves, suitable for the pillars of summer-houses and 

 the posts of arbours or pergolas ; also varieties of more robust growth, with very large 

 foliage, for entirely covering arbours, arches, or pergolas, in shady spots, or, indeed, 

 any positions. The plants, moreover, grow in almost any kind of soil, but the richer 

 it is the better the progress ; in dry poor soil ivy is often long in getting established 

 and such soil is the cause of many failures with these (when established) accommodating 

 plants. Ivy is increased by cuttings six inches long, two-thirds inserted in sandy soil 

 under hand-lights in the autumn.
