August. 
Virginica, Vivid. (G.L. )

blooms three weeks later than the others, the flowers are a deeper pink; much larger and better, 
lasting a long time when cut.

habit, 2 to 2£ feet high, producing their attractive blue or white flowers from July to October. 
They are very satisfactory hardy plants for the sunny border. 
Culture: Must be grown in a light, more or less sandy,soil, in a well drained, sunny border. 
If the border is slightly elevated so much the better. Plant in early spring or fall, eight 
inches apart. Disturb as little as possible, as these plants do not start to show new growth 
until the middle of May, care should be taken that they are not destroyed.

border.

colbalt-blue flowers on wiry stems always make a beautiful showing in the garden. 
Culture: In the colder regions the plants need protection during the winter. They grow well in 
sunny places or partial shade and in any good garden soil. 
*Larpentae. (L. )

• only 6 to 8 inches high, covered with colbalt-blue flowers during late summer and fall.

Coeruleum Alba. (G.L. ) 
A white form of the above. 
PRIMULA. Primrose. English Cowslip. Polyanthus. 
Hardy primroses are showy plants; are interesting plants suitable for the rockery, the waterside 
and the border. Many of the flowers are fragrant and make splendid cut flowers. No garden is 
really complete without a liberal planting of them. 
Culture: Primulas are not at all difficult to grow, if a few of their simple requirements are 
known. Cne of the first requisites is to keep the soil moist, and for best results, they should 
be planted where they could have shade at least during the heat of the day. The plants will die 
if they are allowed to pass through the dry summer without plenty of water. An ideal place to 
plant them would be in rich, well drained soil, in a shady nook in order to protect the plants 
from the hot sunshine during the summer. c light protection during the winter is needed, a 
light mulching of leaves or straw will answer the purpose. A damp, rich loam, freely mixed with 
leaf mold and peat is necessary for best results, as the peat tends to hold moisture.

bearing heads of bloom of various colors; very fragrant. Compact and slow growing plants.
