u6 PRESENT-DAY GARDENING 



is an attractive, easily managed greenhouse climber, and 

 hardier than was formerly thought. It should be planted in 

 light or peaty soil, with the protection of a wall in a warm 

 situation, and the stem should be covered if likely to be 

 subjected to severe frost. R. crocospermum (R.jasminoides 

 angustifolid) is hardier, with orange-centred flowers. Pro- 

 pagation by cutting of the young shoots in heat. 



ROSA 



The many beautiful climbing Roses, which thanks in a 

 measure to the popularity of the pergola are now better 

 represented in many gardens than formerly, are dealt with 

 in Chapter VIII, p. 40. 



RUBUS (see Plates IV and V) 



A number of species, chiefly Chinese, are ornamental 

 climbers. R. deliciosus, Rocky Mountain Bramble, one of 

 the finest of the hardy sorts, is without spines, out will 

 clothe a wall ; it has white flowers resembling Dog Roses. 

 R. odoratus is well adapted for planting under trees, has 

 large clusters of purple flowers, and fragrant leaves. R. 

 phoenicolasiiiSj Japanese Wineberry, has scandent stems 

 covered with reddish hairs, and its leaves are white under- 

 neath. R. ulmifolius has stems which attain 15 to 18 feet 

 in length ; there is a variety with double pink flowers. R. 

 moluccanusy the Himalayan Blackberry, and R. reflexus, 

 stems 30 feet or more, are two of the most ornamental of 

 the more tender species, being serviceable as greenhouse 

 pillar plants. Rubuses are easy to grow, but respond to 

 liberal cultivation. Division or layering the young growing 

 shoots are methods of propagation.
