THE GREEN-HOUSE. 



flowering during the winter. All the culture they 

 require is thinning, and protection by mats over the 

 glass in severe weather. In summer the sashes may 

 be taken off, and ihe soil covered with black stones 

 like rock-work to attract and refract the heat.' (^Hort.

 is protected by being placed against the front wall of 

 a hot-house. 



Subsect. 7. Bulbous-rooted Green-house 

 Plants, 



There are a considerable number of bulbous- 

 rooted plants which are inhabitants of the green- 

 house, and a number of them usually grown in the 

 dry-stove will live there. This class of plants, how- 

 ever, have no show excepting when in flower, and 

 half the year at least they have not even leaves, being 

 wholly dormant under the soil. We advise but very 

 few of them, therefore, to be admitted into the villa 

 green-house, and these few we think should be 

 brought to it only a few days before they come into 

 flower, and taken from it immediately after their blos- 

 soms begin to fade, and kept in frames or pits all the 

 rest of the year. We shall enumerate some of the 

 most showy green-house bulbous plants, chiefly in 

 the order of their flowering.
