250 GREEN-IIOUSE — REPOTTING. [^Marcll. 



much amalgamated that the named sorts will not be distin- 

 guished. A green-house without some of the choice varieties 

 of this plant is deficient of a flower whose beauty and grand- 

 eur are beyond the highest imagination. It is a native of 

 Nepaul, in India, and when found by Dr. Wallach, awakened 

 the ambition of every cultivator and connoisseur in Europe.* 

 There are several other species lately brought from that 

 country, which are highly valued: the species are R. cam- 

 jyaiiulafiwi, R. anthojwf/on, and R. cinnamomum. They 

 are rarely seen in our collections, but a few years will make 

 them more plentiful. Their beauty of flower is beyond de- 

 scription. The pots should be well drained, and if they are 

 large, put several pieces of sandy stone or potshreds around 

 the side, for the fine fibres delight to twine about such, being 

 mountainous plants. When growing, give copious waterings 

 at the root. For young plants, soil No. 6. And for bloom- 

 ing plants, use one portion of leaf mould. 



Roelkii^, pretty leafy shrubs, with blue terminal funnel- 

 shaped flowers, lip-spreading; R. cilliata, R. qnccita, and 

 R. pedunculata are the finest of the genus. The pots must 

 be well drained, and care taken that they are not over-wa- 

 tered. (Soil No. 6.) 



SdUia (Sage) is an extensive genus of soft-wooded, shrub- 

 by, or herbaceous plants ; very few of them do well in the 

 green-house, and many of them are very trifling, having no 

 other attraction than the flower; and those of the tender 

 species, when compared witb S. fulgens, crimson, S. splin- 

 dens, scarlet, S. angustifolia, pale blue, S. patens, dark blue, 

 >S^. involucrafa, pink (which in artificial climates constitute 

 the standard of the genus), are not worth cultivation. The 

 best method to adopt with the summer flowering kinds is to 

 plant'them in the garden in May : they will grow strong and 

 ^ flower abundantly, and in the fall they can be lifted, and 

 preserved during winter in pots. They neither grow nor 

 flower so well as when planted out, and even a slip planted 

 in the ground in moist weather will root in a few days, grow, 

 and flower in a few weeks. S. splendens is the best to select 

 for the purpose. All will grow easily with encouragement.
