LEADWORT FAMILY 



The flowers are separately stalked, but clustered in dense hemi- 

 spherical heads, surrounded by an involucre of bracts whose bases 

 are continued as a translucent tube some distance down the scape. 



Armeria vulgaris, the most common form in cultivation, makes 

 broad tufts of dark-green, linear foliage and bears its purplish- 

 lilac flowers in loose heads, on stems averaging six inches high. 



Thrift Artnh-ia vuigiris 



The name Thrift apparently was given by some one who marked 

 how the plant growing on the scantiest soil possessed that virtue 

 which made good use of small things. 



Shrubby Plumbago, Plumbhgo capensis, is a tender South Afri- 

 can climbing shrub, which is often turned out from the green- 

 houses in late spring to bloom in the garden until frost comes. 

 The inflorescence in flower and cluster suggests phlox, but the 

 color is a soft azure blue.
