effective and useful of our garden Alpine plants, excellent 

 for walls and edgings, where it will spread out over the 

 path in beautiful patches, alternating well with similar 

 groups of yellow Alyssum and herbaceous Candytuft. 

 Purpurea is the oldest variety, and from its habit most 

 suitable for growing over stones on the rock garden. 

 Campbelli is fine, with large, deep violet-purple flowers, 

 and Leicktlini, a bright reddish crimson. Short side-

Dianthus barbatus (Sweet William) is one of the
