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 (Antennaria), and any of the encrusted 

 Saxifrages ; or separately with the charming Phlox

There are some little plants that grow in sheets,

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

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

 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

 plants of Alpine origin that have long been grown in
