BEAUTIFUL GARDEN FLOWERS. 
white and intermediate shades, and strenuous efforts 
have been made to perpetuate a race of “ Blue ” 
Primroses. The true blue Primrose, however, is still a 
long way off, and it may be noted that the nearer the 
plants get to this colour, the more difficult they are as 
a rule to cultivate and increase. In addition to the 
single-flowered Primroses of various shades, there are 
also double ones equally varied in colour. A rich 
sandy loam and leaf soil, and partially shaded spots 
in the rock garden will suit the stronger growing 
kinds perfectly ; but unique or very rare specimens are 
safer grown in cold frames. 
With the ordinary Primrose, the Cowslip (P. offici- 
nalis), and Oxslip (P. elatior), may be grown, and 
receive similar treatment in shady dells, pastures, or 
banks. As it is impossible to give detailed descriptions 
of all the wild species of Primula here, it is only 
necessary to say that they may nearly all be grown 
without much difficulty in the open air, provided a 
well-drained sandy loam and leaf soil is used. Many 
of them ripen seeds freely, and in this way they may be 
increased as well as by division after flowering is over. 
For more detailed particulars as to descriptions ? 
&c., of the Primulacese the reader is referred to the

PRUNELLA grandiflora ( Self Heal).— A pretty 
perennial, about 6 inches high, with ovate leaves and 
erect trusses of violet or purple two-lipped flowers. 
The variety alba has white Dead-nettle-like blossoms, 
and Webbiana has crimson-purple ones. The plants 
are easily increased by division in spring, or from seeds. 
PULMONARIA (Lungwort ). — These rather coarse-
