planted sixteen years ago and have never once failed 

 to make a splendid display. The surface-soil should 

 be pricked over early in spring. 



HIPPOPH^C RHAMNOIDES (the Sea Buckthorn). 

 This will succeed well in any deep moist soil. Its 

 beautiful grey foliage shows up well during summer, 

 and when the male and female plants are mixed

 apart and prune close to the ground annually early in 

 April. H. calycinum (the Common St. John's Wort) 

 is partly evergreen and admirably suited for clothing 

 banks or making beds where low-growing subjects 

 are required ; it will flourish anywhere, and should 

 be cut close to the ground with the shears annually.
