TO THE FLOWER GARDEN. ^41 



ROSE BAY. See Rhododendron. 



ROSMARINUS. Rosemary. [Lamiaceae.] Hardy ever- 

 green aromatic shrubs. Light dry soil. Cuttings. 



RUBUS. Bramble. [Rosace£e.j Hardy trailing shrubs 

 for the most part. Rich loam. Cuttings and layers. A 

 very extensive genus ; for the most part are adapted for 

 gardens. 



RUDBECKIA. [Compositae.] Showy hardy herbaceous 

 perennials, from which the species of Echinacea, Oheliscaria, 

 Centrocarpha, and Dracopsis have been separated. Increased 

 by seeds sown in May, to produce flowering plants for the 

 next year, or by dividing the old roots any time in autumn 

 or spring, and planting the divisions with pieces of root 

 attached. They grow readily in any good connnon soil. 



RUSCUS. Butcher's Broom. [Liliacese.] Hardy ever- 

 green under-shrubs. Common soil. Suckers. 



R,USSELIA. [Scrophulariaceae.] R. juncea is a beautifal 

 drooping stove plant, with long pendulous branches, and bear- 

 ing in summer splendid scarlet tubular flowers. The plant, 

 if well grown, and not too rapidly advanced, produces such an 

 abundance of bloom, that when in flower it is a most striking 

 object, even in large collections ; but if it be forced too much 

 the plant is not half covered. Fibry loam and turfy peat, 

 well mixed, good drainage one-third up the pot, and a heat 

 of 65° to grow in by day, and 60° at night in the winter time, 

 will bring the plant forward in perfection. This plant must 

 have but one-size shifts at a time from the first potting into 

 three-inch pots, into five-inch, and from five to six, and so on 

 until it is in a No. 4. This shifting must not take place 

 until the respective pots are v>ell filled with roots. When 

 once well established it will bear a good deal of water ; but 

 the cuttings and small plants must only be kept moderately 

 moist. Cuttings root freely in sand on the top of the usual 

 soil ; but they requii'e a little bottom heat, and a bell-glass to 

 cover them, and this must be wiped daily. The plants hang 

 down all round the pot, which must be placed on a pedestal 

 in full light, and be consrantly turned, that it may be all 

 round alike. 



SABBATIA. [Gentianaceag.] Hardy or half-hardy bien- 

 nials and perennials. They grow best with the aid of a gieen-
