the young plants give the best spikes of bloom ; 

 two feet, flowers late in June. 



G. grandis, rather like the preceding, but the 

 flowers are set close to the stem, and it flowers a 

 little later. 



C. carpatica is about nine inches high, blue 

 or white, grows into large tufts (which can be left 

 unmolested for years), likes a sunny place, and 

 flowers in July and August ; it is easily divided. 



C. pyramidalis is a very tall species, three to 

 six feet, blue, or white. It makes lovely effects in 

 August and September when planted in groups; 

 the seed should be sown in May and grown on for 

 the following year. Though it is called perennial, 

 it generally behaves like a biennial and dies after 

 flowering, so you should bring up a stock each 

 year. 



C. celtidifolia is good, two feet high, pale-lilac, 

 flowering in July, and of long continuance. 



C. macrautha, blue or white, is a handsome- 

 looking plant with tall upright spikes of hanging, 

 bell-shaped flowers, and has the merit of growing 

 quite well in shade or under trees, but the flowers 

 last a very short time; it is easily raised from seed, 

 or it can be divided.
