Primula Auricula marginata (Europe). 
A valuable plant for dry fissures of rockwork 
facing south or east in strong loam and limestone. 
When planting in a long crevice, clay should be 
used instead of loam, to wedge the plants tightly 
between the stones, starting at the bottom of the 
crevice and working upwards. A piece of limestone 
should be placed between every two plants, and clay 
pressed close to the roots between the stones; thus 
a beautiful effect will be obtained all the year round. 
Primula Balbisii (Baldo, Alps of S. Tyrol, etc.). 
Treat like Primula Clusiana. 
Primula calycina (Alps of Lombardy). 
Plant in a well-drained position, having a north- 
east aspect, in half limestone and half rough loam. 
Primula capitata (Himalaya). 
Plant this species in a shady place on the flat 
facing north or north-west, in good loam. In early 
spring take hold of the plant, and if it comes away 
easily in the hand look for a small white grub in the 
collar of the plant. If this is present the plant should 
be cleansed and replanted in another position ; 
should, however, there be no reason to suspect the 
presence of any such offender, simply press back the 
plant into position, and add a top-dressing of the 
original compost around it.
