Trailing Annuals 
vitalia procumbens, like a tiny trailing Sunflower, 
is nowhere so well in place as on a sunny rock 
shelf. Another trailing annual is the coppery 
Anagallis Wellsiana, and the blue A. Webbiana 
should not be neglected. Several of the annual 
Linarias are better suited for the rock garden 
than elsewhere ; the best are L. reticulata aurea 
purpurea, L. alpina, and the varieties of L. 
maroccana. The tiny Ionopsidium acaule is 
beautiful in cool nooks and bare places where 
it will not suffer from drought. Silene pendula 
and Saponaria calabrica are both capital rock 
plants. Others that can well be used are 
Dianthus sinensis and the dwarf forms of Phlox 
Drummondi, also Phacelia campanularia, whose 
pure blue is always welcome. The prostrate 
habit of the Ice-plant also makes it suitable, 
and the deep green of its glistening crystal- 
beaded foliage assimilates well with the per- 
sistent greenery of the permanent plants. 
A whole large space of rock garden may be 
made beautiful in late summer by a June 
planting of one of the dwarf bedding Lobelias 
in every empty space or chink that is available ; 
in a large rock garden such a filling with one 
good plant at a time would be found restful and 
satisfying, and would help to correct the slightly 
disquieting impression so often received in such 
a place, from too many objects of interest 
being presented within one range of vision.
