precedence to any one, Achillea umbellata takes high 

 rank. The two illustrations in the chapter on the 

 Sunny Rock-wall (pp. 6 and 7) show it both in summer 

 bloom and winter foliage. With this charming thing 

 I should group some of the plants of low-toned 

 pink blossom, such as Thrift and the pink-flowered 

 Cudweed {Anteunaria), and any of the encrusted 

 Saxifrages ; or separately with the charming Phlox

There are some little plants that grow in sheets, 

 whose bloom is charming, but on so small a scale

 of this small, dainty class, best accompanied by things 

 of a like stature, such as Arenaria balearica, and per-

 balearica is a little gem for any cool rocky place ; it 

 grows fast and clings close to the stones. It always

 shows a little dark patch on its surface, first flowerless 

 and then dying away, while the outer fringe of the 

 patch grows onward. Aubrietia, Arabis, Iberis, and 

 Cerastiumy four of the commonest of spring-blooming 

 plants of Alpine origin that have long been grown in
