BLUE GARDENS

sufficiency of the colour, clumps of white 
Bermuda lilies are added, and concealed tubs 
filled with blue agapanthus. Some of the more 
graceful tree stems were left when the under- 
growth was cleared out, giving partial shade to 
masses of ferns. 
Many of our best gardeners do not believe in 
a border entirely of blue flowers, and in most 
cases it is well to exercise individual taste, 
occasionally breaking an otherwise monotonous 
scheme by the introduction of some grouping 
of grey-foliaged plants such as Artemisia cana 
and frigida , stachys or santolina, or the glaucous 
green of Funkia Sieboldii , and the vivid green 
of Funkia japonic a. White or cream-coloured 
flowers always look well, and Campanula persici- 
jolia alba , with white bells on tall, graceful 
stems, some of the creamy spiraas, a good 
white phlox such as Sylphide, and white fox- 
gloves, may be used. The tall, pale-yellow 
Thalictrum glaucum and Gaura Lindheimeri , in 
long slender spikes of pink and white, look 
well against Eryngium planum or echinops. 
A terrace garden could be made very interest- 
ing if planted entirely in blue flowers, care 
being taken to eliminate all muddy or dull 
shades such as tracheliums or ageratums, with 
a mellow, pinkish brick wall as a background.
