BILLBERGIA 



can withstand an abundance of moisture, at the roots 

 as well as at the top, most o£ the time holding water in 

 the funnel-like center or body of the plant. They gener- 

 ally bringtheir conspicuous, showy fiowers in the spring, 

 when moisture overhead or sprinkling should be with- 

 held in order to prolong the beauty of the flowers. They 

 require at night a temperature of from 50°-75°, but, of 

 course, can stand any amount of heat in summer. Bill- 

 bergias, like all other Bromeliads, make very good house 

 plants, and they will thrive exceedingly well in a living- 

 room temperature. They love plenty of light and sun. 

 All flrst-class private garden establishments should 

 have at least a few of this class of plants. They are 

 propagated best from suckers or sprouts, which arise 

 from the base of the old plant, generally after it has 

 bloomed and performed its functions. The old plant 

 then gradually deteriorates, sending out from two to five 

 young plants from its base. These can be taken off as 

 soon as they are hardy and substantial enough, and can 

 be mounted or potted into the same kind of material. 

 Then, suspended in the greenhouse, conservatory, or 

 window for an exhibition, they thrive best. Besides 

 their beautiful and attractive flowers, they have very 

 handsome foliage, which is of a tough and leathery 

 texture. Billbergias, ^chmeas, and the like, are na- 

 tives of the tropics, and, therefore, require a warm tem- 

 perature. Jichmeas are usually larger than Billbergias 

 and Tillandsias. Quit, by H. A. Siebrecht.
