PRIMULA - Primrose 
Primroses, Cowslips, and Oxlips are among the plants of song and story. 
They are none too common in American gardens, chiefly because they do not 
like hot, dry situations and need the moist, deep ground along a stream-bank 
or the deep shade of deciduous trees or shrubs. Given the locations they 
like, and a few leaves scattered over them in autumn, even the fine hybrid 
strains thrive in a wonderful fashion. 
*Primula auricula. Auricula. 10 in. May, June. Attractive rosettes of 
thick leaves often covered with a mealy down. The flowers are large and 
round, borne in a cluster on the top of short, erect stems, and come in

*P. cachemiriana. Kashmir Primrose. 8 in. June. Clusters of leaves which 
are heavily dusted with meal on the under side. Flowers large, purple-blue 
with a golden eye, clustered on an erect stem. Rare and handsome. 
*P. japonica. Japanese Primrose. 2 ft. June, July. Strong, handsome 
plants for rich soil in shady places, producing fine clusters of flowers of 
light pink and cream shades on the top of slender but strong, erect stems. 
Plant in moist soil near a bog or stream, if possible. 
*P. polyantha, Munstead Strain. 10 in. May, June. A splendid strain of 
the popular Polyanthus, comprising flowers of many charming shades of 
yellow, cream, and dark orange. Prefers shade but not moisture like

ers of varying shades of red and crimson. 
*P. polyantha, Sutton’s Giant Mixed. 10 in. May. A vigorous English 
strain of mixed colors. 
*P. polyantha, Sutton’s Giant White. One of the best strains. Large 
flowers of pure white.

the rock or woodland garden or in combination with Myosotis.

*Pulmonaria angustifolia azurea. Azure Lungwort. 10 in. May, June. 
Often confused with Mertensia, this vigorous, dwarf plant with long, rough 
leaves produces a profusion of pink clusters that open to the purest blue.
