PERENNIAL PHLOX. This notable family of hardy perennials is 

 perhaps the most widely known and popular of all the various plants which 

 we have in our gardens, and each year finds the newer and showier varieties 

 increasing through the hybridizer's skill. Certainly no perennial is more 

 worthy of culture, more satisfactory in every situation, or more effective, either 

 as individual plants or grouped in masses in shrubbery beds. All of the 

 Phloxes, with the exception of the dwarf form, are well adapted for cutting, 

 and are exceedingly floriferous. The plants begin to bloom in midsummer, 

 and the garden borders can be kept aflame with great flower-cones from June 

 until frost. Already they run through the whole gamut of colors in shades 

 delicate or deep and rich, with flowers ringed, eyed, shaded and self-colored. 

 Although the Phloxes are bold and hardy in their growth, thriving even in poor 

 soils and situations, they appreciate deep, rich ones, and pay a royal tribute to 

 all extra care bestowed. Every shoot of the plants is usually topped by a 

 heavy pyramidal cluster. (See plate on page 172.)
