THE NURSERY-LIST 413 



stocks are grown either from seeds or cuttings. A common stock is 

 the manetti, which is a strong and hardy type, and the resulting 

 budded plant may be used for regular garden work or for forcing 

 under glass. The eyes should be cut out of the manetti stock below 

 the bud, to avoid sprouting. Because the manetti suckers badly, 

 various wild briars are much used in Europe. The bud is often in- 

 serted 2 to 4 feet high, making " standard " roses (Fig. 127). These 

 are practically unknown in this country, except as sparingly im- 

 ported. 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 cuttings. For outdoor propagat- 

 ing, they are " dressed " much like apple stocks (Fig. 132), and are 

 budded the year in which they are planted in the nursery row. The 

 gardener may grow his own stocks of these (particularly of multi- 

 flora) from hardwood 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 for some of the hybrid 

 perpetuals, with excellent results, is Rosa Watsoniana, a Japanese 

 species. This is a slender stock, and is grafted, not budded. 

 " Worked " roses are in greater favor in Europe than in this country, 

 and our various native roses have, therefore, received little attention 

 as stocks. The common sweet briar of the roadsides (which is an 

 introduced species) is sometimes used for stocks. R. Wichuraiana is 

 easily propagated by long cuttings of year-old wood in the open air. 



Rosmarinus (Rosemary). Labiates . 

 Increased by seeds and division. 



Roystonea : Oreodoxa. 



Rubiaceae. Rubiads. 



Propagation of most of the genera is by cuttings of the partially 

 ripened young wood in good bottom heat ; also by seed and a few by 

 root-cuttings. The herbaceous kinds are increased by division and 

 seeds. As well as ornamental garden subjects, many of the rubi- 

 ads are most important economic plants. 



Rubus (Bramble). Rosacece. 



Increased by seeds, which should be stratified or sown as soon as 

 ripe. Divisions of the clump, natural stolons, root-cuttings and
