108 FAMILIAR GARDEN FLOWERS. 



on a wire balloon, or any kind of trellis that may be pre- 

 ferred. Having flowered, they should be destroyed, and 

 the stock of specimens kept up by a succession of young 

 plants. 



It is a simple matter, and especially worthy of the 

 attention of amateur cultivators, that the verbena may 

 be grown as an annual from seed, and will afford a de- 

 lightful display of colour in the summer and autumn. 

 The seed may be sown in autumn, and the plants may 

 be wintered on a shelf near the glass, and being shifted 

 in March to insure vigour of growth, may be planted out 

 in May for flowering. But where this routine might be 

 inconvenient, sowing in March will suffice; a moderate 

 heat will soon bring up the seed, and the young plants 

 will need only the usual treatment of half-hardy annuals 

 to insure the most satisfactory results.
