TREES FOR THE ROCK GARDEN 147 



be complete without some reference to Yuccas, which 

 for all practical purposes must be included under 

 that head. Groups of these magnificent plants, with 

 their sub-tropical effect, cannot be surpassed for 

 nobility of outline and stateliness of flower. To do 

 them full justice, they must have space to develop 

 their grand proportions, but this may often be found 

 on the ridge or upper slope, even in rock-work of 

 limited character. Y. gloriosa, with its fine form, 

 K recurva, and the stemless Y. flaccida, of smaller 

 growth, are amongst the best and hardiest kinds, 

 and to these may be added Y. angustifolia, another 

 valuable and nearly stemless species. 



It is only possible, in restricted space, to touch 

 in a very cursory way upon a few of the available 

 groups of dwarf-growing shrubs. Many more than 

 have been mentioned will occur readily to the minds 

 of those who are at all conversant with plants, such 

 as Abelia rupestris. Magnolia stellata, several beautiful 

 species of Daphne, some of the St. John's Worts, of 

 low-growing Cyfisus, and others which may be classed 

 under the head of miscellaneous. The subjoined 

 list, though it does not pretend to be exhaustive, 

 will be found of use, either for purposes of winter 

 greenery or for summer embellishment, by those 

 who are seeking good and suitable dwarf shrubs 

 for planting, under varied conditions in the Rock 

 Garden.
