Compared with a sister species, Phlox Drummondii, the ‘‘ moss 
pink” appears to be much more variable in nature. The r, 
however, has under cultivation since 1835, i 
time there have developed o recognized horticultural 
varieties,* which, considered as a , exhibit uch wider 
of selection, when a relatively simple sp is cultivated in- 
tensively in new climates and special atten paid to the 
propagation of variations. at the limits of such variation 
uld be for Phlox subulaia were it given the same floricultural 
treatment can only be conjectured.
