on the lawn, or near the edges of streams, ponds, &c., 
or may be grown in the rougher parts of large gardens. 
P. orientate, an annual species, grows 3 to 10 feet high, 
having large downy oval acute leave, and drooping 
racemes of rosy-purple flowers in August. It is raised 
from seeds sown in gentle heat about March. The 
perennial kinds mentioned above are easily increased 
by division in spring. 
POTENTILLA ( Cinquefoil ). — About 120 species 
are known, but many of them are mere weeds. From 
a decorative point of view, the double-flowered garden 
forms that have been developed from the purple- 
flowered P. nepalensis, and the deep crimson P. argy- 
rophylla atrosanguinea are the most attractive. 
Numerous named varieties, 2 to 3 feet high, are 
to be found in nurserymens’ catalogues, and great 
diversity of colour exists among them — red, yellow, 
orange, crimson and purple predominating. They all 
like a well-manured sandy soil, and may be increased 
by division of the rootstocks in spring. 
PEJMULA (Primrose) . — With the exception of one 
or two species from the cold regions of South America, 
there are 150 or more species of Primrose distributed 
throughout the temperate parts of Europe, Asia, and 
North America. Comparatively few of them are 
known outside botanic gardens, and although they 
may all be said to be pretty, it is questionable whether 
any of them can surpass or even equal the common 
British Primrose (P. vulgaris ) in grace or beauty. 
There are now many forms of it considered to be of 
garden value. In these, the yellow colour has given 
way to shades of lilac, rose, mauve, bluish-violet, pure
