196 PRACTICAL FLORICULTURE. 



ing to the roots, as they wilt very easily, and the plants 

 require great care in lifting. In any case, it is necessary 

 to shade and freely water for six or seven days before 

 exposing them to full sun. They had better be stood in the 

 open ground or in a cold frame, after being potted, rather 

 than put in a greenhouse, as it is very necessary that they 

 be fully exposed to light and air for as long a time as pos- 

 sible, before placing them in their winter quarters in the 

 greenhouse ; but this outside exposure must not be 

 risked too late, not later than October 1st, in this lati- 

 tude, unless they can be covered up before there is danger 

 to be apprehended from frost, as the Bouvardia is a very 

 tender plant, and will be injured by a very slight degree 

 of frost. They may either be grown in pots, or planted 

 out from the pots to the benches, as we do with Carna- 

 tions and many other things. Our own practice, as we 

 have before said, is to set all such plants out in the 

 benches, as the flowers produced are much finer, owing to 

 their having a more regular condition of moisture at the 

 roots ; besides, this gives a greater area for the roots to 

 run in. We have said the Bouvardia is a hot- house 

 plant ; therefore if flowers are wanted in the early part 

 of winter, the temperature at night should range from 

 fifty-five to sixty-five degrees. The leading varieties of 

 Bouvardia are : Double Pink ; Double White ; Elegans, 

 single, bright carmine ; Vulcan, single, scarlet ; Priory 

 Beauty, single, rose color ; Dazzler, single, deep scarlet ; 

 Vreelandi, single, white; Humboldti is a beautiful, Jessa- 

 mine-scented variety, with large, waxy-white flowers, but 

 it is only useful in early fall and in spring, as it will not 

 flower freely in midwinter. Bouvardia flowers sell at 

 about $2 per hundred trusses. 



STEVIAS AND EUPATORIUMS. 



Stevias and Eupatoriums are yet much used for winter ; 

 they are white-flowering plants, of no particular beauty
