THE ROCK-GARDEN 93 



gardens, are capital companions, making sheets of 

 hanging or trailing bloom at that flowery time when 

 spring joins hands with summer. The palest coloured 

 of the Aubrietias, such as the variety " Moorheimi," 

 are among the best, and should not be neglected 

 in favour of the stronger purples only. 



A little later in the year Campanula pulla and Silene 

 alpestris do well together, plentifully framed with 

 small Ferns and Mossy Saxifrages. The lovely Iris 

 cristata is charming with Corydalis capnoides of the 

 pale yellowish white bloom and bluish almost feathery 

 leaves. 



In the upper and bolder regions of the rock- 

 garden where there will be small shrubs, the fine 

 blue-flowered dwarf Flag Iris, /. Cengialti, should 

 be grouped under a bush of Eurybia gunniana. 



London Pride, the best of the Saxifrages of that 

 class, should be plentifully grouped with strong 

 patches of the lovely white St. Bruno's Lily, backed 

 by some bushes of dark foliage as of Gaultheria 

 Shallon or Alpine Rhododendron. 



It is one of the pleasures of the rock-garden to 

 observe what plants (blooming at the same time) will 

 serve to make these pretty mixtures, and to see how 

 to group and arrange them (always preferably in 

 long-shaped drifts) in such a way that they will best 

 display their own and each other's beauty ; so that 

 a journey through the garden, while it presents 

 a well-balanced and dignified harmony throughout its 

 main features and masses; may yet at every few steps 

 show a succession of charming lesser pictures.
