 soil. The plant forces well and easily in a coolhouse for 

 early spring flowering. It is tenacious of life and gen- 

 erally easy to manage.

Var. floribiinda is more suited to pot culture in pots 

 and flowers more freely when small than the type. 

 Lusidndra, or Plerdma spUndens, Hort., should be 

 compared with this. T. neniidecandra is a plant of easy 

 culture that has been highly praised by several con- 

 noisseurs. Cuttings struck in April will give bushy 

 plants for fall and winter blooming. Handsome speci- 

 mens may be had by keeping the same plant two or 

 three years, training it to wires or stakes in a cool- 

 house where it has plenty of root room. The flowers

last but a day or so, but new ones open up every day 

 and the flowering season lasts for several weeks. 

 Plants may also be used for summer bedding. They are 

 seldom out of bloom. The species is much esteemed in 

 Florida, where it makes a showy shrub 8 ft. high. It 

 endures a few degrees of frost with impunity, and even 

 if cut down it sprouts readily.
