83 Bulbous-rooted and Rock Plants. 



CHAPTEE, XIII. 



BULBOUS-EOOTED AND EOCK PLANTS. 



i S I said in a former chapter, a small rockery 

 I under your window in connection with, your 

 window hox could be so arranged that rock- 

 ery, window box, and creepers would appear to form 

 One harmonious whole. Such a window in the height 

 of the season would have a beautiful effect, and be the 

 admiration of every passer-by. Clinkers from a furnace 

 make a nice rockery. A few white pebbles and shells 

 heighten the effect. Raise a mound of soil and build 

 your materials over it as naturally as you can, leaving 

 crevices in which to plant your roots and flowers. 

 I will select a few of the most suitable plants for a 

 rockery. 



Aubrietia. — A lovely little rockplant of many varie- 

 ties, with green and variegated foliage. Grows in a 

 dense tuft or mass. 



Cerastium tomentosum. — A silvery foliaged mouse-ear 

 chickweed ; flowers white. 



Arabis. — A hardy class of spring flowering plants 

 suitable for rock-work> of various kinds, green and 

 variegated; flowers white.
