and the "American V. cucullata, blue, white or striped. 

 The Violas are easily raised from seeds, sown as directed 

 in the chapter dealing with the subject ; they may also 

 be increased by division, or, in some cases, by pegging 

 down the creeping stem-like growths called runners. 



Wahlenbergia. The Wahlenbergias bear a great 

 resemblance to the Campanulas, and belong to the Bell- 

 flower family (C ampanulaceae) . They are charming 

 little plants of low growth, with comparatively large 

 blooms. They are not difficult to grow in the moraine 

 or in very gritty, well-drained soil. W. pumilio is the 

 chief favourite ; it has greyish leaves, and showy, 

 lilac-blue, erect blossoms in May. W. serpyllifolia, with 

 tiny leaves and purple-blue flowers, W. Kitaibelli, blue- 

 purple, and W. saxicola, lilac-blue, are among the best 

 of the other kinds. Propagation is effected by division 

 after flowering, or, better still, by seeds in spring.
