312 THE NURSERY LIST. 



Rosa (Rose). Rosacecc. 



New varieties, and sometimes stocks, are grown from 

 seeds, which are sown as soon as ripe, or kept in the hips 

 until spring. The hardy kinds are usually sown in well 

 prepared beds outdoors. Roses are sometimes grown 

 from layers, and often from root cuttings, after the manner 

 of blackberries. The common way of propagating roses, 

 however, is by means of short cuttings of firm or nearly 

 mature wood, handled under glass, with a mild bottom 

 heat (65 or 70). They are commonly made in February 

 or March from forced plants. The cuttings are made in 

 various fashions, some persons allowing most of the leaves 

 to remain, and some preferring to cut most of them off, as 

 in Fig. 74. They are commonly cut to one-bud lengths, 

 like Fig. 76. Long cuttings of ripeued wood, handled in a 

 cool greenhouse or in frames, may also be employed for 

 the various perpetual and climbing roses. Most growers 

 feel that the best plants are obtained from cuttings, but 

 most varieties do well when budded upon congenial and 

 strong stocks. Budding by the common shield method is 

 considerably employed, and veneer-grafting is sometimes 

 used. The stocks are grown either from seeds or cut- 

 tings. A common stock is the manetti, which is a strong 

 and hardy type. The eyes should be cut out of the ma- 

 netti stock below the bud, to avoid sprouting. Because 

 the manetti suckers badly, various wild briars are much 

 used in Europe. The bud is often inserted 2 to 4 feet 

 high, making "standard" roses. These are practically 

 unknown in this country, except as sparingly imported. 

 The multiflora rose is also a good stock, especially for 

 early results. These manetti and multiflora stocks (and 

 some others) are imported from Europe as yearling cut- 

 tings. For outdoor propagating, they are "dressed" 

 much like apple stocks (Fig. 86), and are budded the year 

 in which they are planted in the nursery row. The gar- 

 dener may grow his own stocks of these (particularly of 

 multiflora) from hard-wood cuttings made in spring, and 

 these cuttings should be fit for working in the following 

 fall and winter. Home-grown seedlings should be two 

 years old (unless very strong) before they are budded. 

 Hybrid perpetual roses make excellent pot plants in a 

 short time when winter grafted, with dormant wood, upon 

 multiflora stocks. A stock somewhat used about Boston 

 for some of the hybrid perpetuals, with excellent results, 

 is Rosa Watsoniana, a Japanese species. This is a slen- 

 der stock, and is grafted, not budded. "Worked" roses
