Aloe. Liliacece. 



Commonly propagated by suckers which spring from the 

 base of the plant. Seeds are sometimes employed. 



Alomia. Composite?. 



Propagated by cuttings. 

 Alona. Nolanacece. 



Increased by cuttings, which root freely in sandy loam, 

 with a very gentle bottom heat. 



Alonsoa. Scrophularinece. 



Propagated by seeds, sown in spring ; also by cuttings 

 in sandy soil, in gentle heat. The herbaceous species may 

 be treated as out-door summer annuals, and should be raised 

 in little heat, and planted out in May. 



Aloysia (Sweet-scented Verbena, Lemon Verbena). Verbenacece. 

 Increased easily in spring by young wood. They will 

 root in about three weeks, in sandy soil with gentle heat. 

 Also by cuttings of ripened wood in autumn. 



Alpinia. Zingiberticece. 



Increased by division after the young shoots have made an 

 inch of growth in spring. 



Alsodeia. Violariece. 



Propagated by cuttings, which root readily under a bell- 

 glass, if planted in sand, in heat. 



Alsophila. See Ferns. 

 Alstonia. Apocynacece,

 Alstroemeria. Amaryllidece. 



Increased by seeds. By a careful division of the fleshy 

 roots, during fall or spring. 



Alternanthera. Amarantacece. 



Commonly raised from cuttings of growing wood. For 

 spring and summer bedding, the plants are started in late 

 winter. The stock plants, from which cuttings are taken, 

 are procured from cuttings made late in summer. Seeds are 

 little used. 



Althaea (Marsh-Mallow, Hollyhock). Malvaceae. 



Increased by seeds, and by divisions. The biennial species 

 must be raised from seeds every year.
