a slight slope, in a mixture of half grit and half poor 
loam. In spring and again in autumn, top-dress with 
the same compost as at first, adding, however, an 
equal proportion of leaf-mould to the constituents in 
the case of the spring top-dressing. The top-dressing 
should be worked well among the young shoots, and. 
any loose ones should be pegged down. Immediately 
after flowering, if the plant appears to have become 
too aggressive, cut it back to within a few inches of 
the main stem. 
Phlox reptans, syn. stolonifera (Alleghany Region). 
Treat like Phlox procumbens. 
Phlox subulata in var. (New York to Florida). 
These all do well on the borders of rockwork, 
and indeed on the front of flower borders, in any 
ordinary soil and with but little drainage. They are 
also most useful for hanging down over the south 
side of stones or on dry slopes of the rockery. In 
wet, clayey ground they keep much longer in bloom. 
Phloxes “ Vivid,” “ Nelsoni,” “The Bride,’ “G. F. 
Wilson ” are among the varieties best worth growing. 
Phlox verna (Gar. Hyb.?). 
Treat like Phlox procumbens. 
Phyteuma comosum (Dalmatia, Carniola, etc.). 
A very remarkable plant, which needs rather 
special treatment. Plant on a sunny part of the 
rockery, where it is fairly dry in winter, wedged 
tightly between pieces of limestone, in a mixture of 
two parts of fine broken limestone and one part of 
strong loam, but without any sand. Do the planting
