dots. Flowers in summer, small, few, 

 almost sessile. 



Culture and Propagation. — Although 

 from sunny Mediterranean climes this 

 species is hardy in ordinary winters in 

 the neighbourhood of London. It must, 

 however, be grown in warm and sheltered 

 spots and in well-drained rather sandy 

 soil. Cuttings of the ripened or half- 

 ripened shoots, without flower buds, may 

 be rooted under a handlight during the 

 summer and autumn months, and trans- 

 planted the following spring. Seeds may 

 also be sown as soon as ripe, if obtainable, 

 and the young plants moved into a warm 

 border the following spring after all danger 

 from frost is over.
