DOGBANE FAMILY 



The value of the plant lies chiefly in its hardy nature and trail- 

 ing growth; so closely do the sterile, creeping stems cling to the 

 ground that the ancients named them serpents. 



Larger Periwinkle. Vinca m^jor 



Half-shaded locations suit it best; poor, stony soil makes a wel- 

 come home and though seeding rarely, the plant loses little, if 

 anything, thereby, as the trailing stems root freely at every joint. 



Larger Periwinkle, Vinca miijor, is larger in all its parts than 

 minor, and not quite so hardy. It roots only at the tips of its 

 sterile stems. A variegated form of it is seen trailing from nearly 

 every veranda box in the country, as it has the merit of withstand- 

 ing considerable neglect.
