THE ROCK-GARDEiN 87 



neat whitish or glaucous-leaved plants, Rock Pinks, 

 Antennaria, Achillea^ and so on. 



Now and then among the small shrubs, and just 

 below the larger ones, a single plant of bold aspect 

 will make a great effect, though the general scheme 

 of planting should be in easy informal groups or long 

 drifts. The kind of plant to use in these points of 

 exceptional isolation is such a one as the best type 

 of Eryngium alpinum, or one of the more important 

 Euphorbias, or a tuft of Yucca flaccida. 



If the rock-garden is very large, larger than the 

 one in contemplation, great groups of the nobler 

 Yuccas are magnificent, but they would be on a scale 

 rather too large for the present garden.
