Trop^olums thrive in any warm, sunn)', fairly moist 

 place. The tops are tender to frost. Fur early etfccts, 

 seeds may be started indoors in pots or boxes. The 

 common climbing species are T. nxtJKx and T. Loh- 

 hirnntw, both of which are very useful for window 

 boxes, Ijaleonies, frir covering banks and walls, and for 

 growing amongst shrubbery. The common dwarf species, 

 T. »ii)i}i.'^, is earlier and usually more tloriferous, and 

 is very useful for the front row in the border. T. 

 pencil )-'nnn)} , the Canary-bird Flower, is grown either 

 indoors or in the open. Probably most species are per- 

 ennial. Many of them are tuberous and withstand 

 some frost at the root; but the half-hardy species are 

 little known in this countrv.
