for the numerous white spines adorning the leaves. 
The above are all natives of Central and Southern 
Europe, and it is said that the foliage of A. mollis 
suggested the idea of the Corinthian Capital. They 
flourish in a sandy loam or well-drained garden soil, 
and, owing to their size and vigour, are perhaps better

The best white-flowered Achilleas are the “ Sweet 
Maudlin” ( A . Ageratum), 6 to 8 inches high; A.
