II HISTORY AND CLASSIFICATION 23 



Boses, or covering waste places, the long shoots 

 being left unpruned. E^licite et Perpetue and 

 Bampant are perhaps the best known among 

 them. 



The BoursauU Eose (Hybrids of B. Alpina). This 

 is another group of strong-climbing summer Boses, 

 with very characteristic smooth wood, not so 

 pendulous in habit as the two last named. The 

 species is a native of the Alps, thoroughly hardy, 

 growing and blooming anywhere with reddish 

 flowers that are often the first Boses of summer. 

 The best-known varieties are Amadis or Crimson, 

 and Gracilis. 



The Banksian Bose (B. Banksias). — This is a very 

 distinct species, said to have been introduced from 

 China early in the last century, and named after 

 Lady Banks. The plants grow very strongly, but 

 are not hardy, and are liable to be killed outright in 

 severe frost even on a south wall. There are only 

 two varieties worth growing — the Yellow, with very 

 small, but full, scentless flowers, produced in great 

 abundance in clusters, and the White, with rather 

 large flowers, most deliciously and characteristically 

 scented, the odour being compared to that of violets. 

 The plants, which are nearly evergreen in mild 

 winters, should be very little pruned (see page 95) ; 

 perhaps the best way is to shorten a little in the 

 summer those shoots that have bloomed, cutting 

 out all dead wood. 



The Polyantha Bose (B. multiflora). — The older 

 varieties of this class, which bloom only once, are 

 single. These are — Polyantha simplex, a great 

 grower, which has been tested as a stock for Tea 

 Boses, but has not proved satisfactory; and P. grandi-
