soil to retain moisture. After the seeds come up, leave 

 one strong plant in each pot. Plants grown from seeds 

 sown in February will bloom in July. 



After the leaves are destroyed by frost, take up the 

 roots and store them in a dry place where they will not 

 freeze. Early plants may be produced by setting roots in 

 five-inch flowerpots in March. If kept in a warm place, 

 the plants will make a strong growth before it is time to 

 set them out. Roots or plants may be set out of doors 

 when all danger from frost is over. Plant cannas in rich 

 garden soil mixed with about half its bulk of rotted ma- 

 nure. Roots should be watered sparingly for a few days. 

 After the plants are started, give them an abundance 

 of water during the summer and keep the surface of the 

 soil well cultivated. Lawn clippings will help to retain 

 moisture. 



THE CANTERBURY BELL 



The Canterbury bell (Campanula) is a hardy biennial 

 plant that blooms the second season after the seed is 

 sown. The flowers are large and the colors vary through 

 shades of lilac to blue, violet, and indigo, and from bluish 

 white to carmine rose. The blooming period is during 

 June and July, and the flowers are especially good for 

 cutting. The plant grows to a height of two or three feet. 



Sow the seed in a light, warm soil. Keep the young 

 plants growing all summer and cover them with leaves 

 and coarse material in autumn. The following spring 

 remove the covering and cultivate the soil.
