1891-92]. CANADIAN WILD FLOWERS. 129 
Dicentra gives us two interesting species. LD. cucullaria prefers rich 
‘soil and moist shade. The leaves are finely cut, indeed the whole plant 
has a most delicate appearance. The flowers, white tipped with light 
yellow, are at once pretty and odd. YD. Canadensis blooms in May. The 
heart-shaped flowers, greenish white tinged with rose, have the fragrance 
of hyacinths. 
We are rich_in Violets. The season of bloom extends from early 
spring until autumn. JV. rotundifolia and V. pubescens are yellow, the 
round-leaved flowering in spring, the other in early summer. JV. cucul- 
fata varies greatly both in the size and color of its flowers, which is 
almost of every shade, from nearly white to the deepest blue. The 
flowers appear in early spring. V.candna, var. sylvestris, (V. Muhlenbergit) 
flowers light blue, and V. Canadensis, flowers white, upper petals often 
tinged with violet on the under side, continue in bloom all summer. V. 
sagittata and V. pedata are large flowers, the latter especially, its flowers 
being an inch in breadth. They both vary from light to dark blue. V. 
pedata is a most elegant plant, its flowers have a delicate and agreeable 
fragrance, and last long in perfection. In grace and beanty it is the 
rival of any exotic. It thrives best in a somewhat sandy soil. The 
white flowered V. d/anda is also, though faintly, sweet scented. All of 
these violets are of easy culture, take kindly to the garden, and increase 
rapidly. 
Two species of Lobelia, L. cardinalis, the flowers a most brilliant 
scarlet, and ZL. sypfhiliteca, light blue, are late summer bloomers, the 
former exceedingly showy, both of easy cultivation, care being taken to 
plant the cardinalzs in moist loam. 
Our Lilies, L. Phzladelphicum, superbum and Canadense, are long since 
to be found in every collection of hardy lilies that makes any pretense 
to completeness. 
Campanula rotundifolia, the only one we have that is perennial, unless 
C. linifolia be accepted as a species, is well-known as the Harebell of 
Europe. It is a pretty graceful plant, grows well in any good garden 
soil, and yields its bright blue flowers in profusion. This is the flower 
referred to by Sir Walter Scott : 
“ F’en the slight Harebell raised its head 
Elastic from her airy tread.” 
We have a large number of pretty things belonging to the Orchis 
family, several of them of such showy appearance as to make them 
desirable ornaments of the garden. By giving attention to the prepara- 
tion of the bed, selecting a cool well shaded locality, and incorporating
