season of the year. These should be planted in 

 pots filled with fresh undungcd earth, and then 

 placed in a shady situation until they have taken 

 root, when they may be turned out into the most 

 sheltered situations of the garden, where they 

 should be planted in clumps of four or six plants, 

 at about eighteen inches' distance from each other — 

 so that when they grow up they appear as one 

 large plant ; and their flowers, although small, are 

 so numerous as to form a mass of blue corollas, 

 each sending forth a style considerably longer than 

 the corolla, which, being headed by a small globu- 

 lar stigma, adds greatly to the beauty of the flowers. 

 Where seeds can be procured, they should be 

 sown in autumn, soon after they are ripe, for when 

 they are kept out of the ground till spring, they 

 frequently fail, or if they do grow, it is not before 

 the following spring. When the plants come up, 

 they should be kept clean from weeds ; and as soon 

 as they are big enough to be removed, they should 

 be transplanted on an east-aspected border of light, 

 imdunged earth. In the autumn they may be 

 transplanted into the quarters of the parterre, where 



they will flower the following summer, from July 



to September. 



Both scientific and vernacular appellations have 



been suggested, by the long tube or neck of the 



corolla ; TracJielium being derived from T§ax'y>>^^^>
