Few of our hardy border flowers fire more pleasing, or of more value as garden orna- 

 ments, than the old Canterbury Bell, called Campanula Medium by botanists— a biennial 

 plant, of pyramidal growth, which inhabits Central Europe, and was'introduced to our col- 

 lections nearly three centuries ago but which still holds its own; and which, whether we 

 regard the forms with single or double blossoms, purple, blue, rose or white, of which it 

 gives a rich harvest, stands unrivalled for its beauty. 



The ordinary single form bears flowers of the shape of a broad cleanly-modelled and open 

 bell, and the usual double forms are made up by the crowding into the interior of this bell 

 of certain peialoid out-growths of the floral whorl, producing a flower on the model of that 

 of a double Petunia. The variety we are now describing, takes quire a different develop- 

 ment. In habit, the plant resembles ihe well-known old blue or white Canterbury Bell, 

 " but the corolla is much larger, and the calyx in Addition is enlarged to nearly 4 inches in 

 diameter, presenting the (orm of a saucer, find changed from its ordinary preen color to 

 the same hue as fiat of the corolla" The broad bell-shaped corolla of the* single rl >wer is 

 perfectly formed, but instead of the usual small leafy ealvx, this organ becomes mach 

 enlarged, and takes on a peta'oid character; and it is this which forms the peculiarity of 

 the flower, and adds so much both to its interest and to its beauty. Price per plant, 30 cents 

 per packet of seeds, 50 cents.
