470 FRITZ BAHR'S COMMERCIAL FLORICULTURE 



Fig. 236. DOUBLE PETUNIAS. A good double, 

 white and pink Petunia always sells during the 

 bedding season. Plants are best propagated 

 through cuttings. Root these early and grow 

 them on cool to produce sturdy plants 



DOUBLE PETUNIAS 



There is a place for the 

 double sorts and they 

 make attractive pot plants 

 for Spring, but there is 

 not the demand for them 

 that there is for the single 

 ones. Most florists who 

 use the double ones exten- 

 sively carry a few plants in 

 pots during Winter and 

 propagate from cuttings. 

 If you have a good plant 

 of white, rose, deep pink 

 or some other color best 

 suited to meet your re- 

 quirements, that method 

 is the only way to increase 

 your stock so as to have it 

 come true. 



Double sorts are even 

 more particular as to per- 

 fect drainage than the 

 single ones and whenever 

 you notice a sickly yellow 

 or stunted growth, you 

 usually can trace the trou- 



ble to conditions involving improper or insufficient drainage. 



Today, September 21st, we filled six window boxes for a new 

 residence with Rosy Morn Petunias. Last July the plants were 

 in 3J/2S, too straggly to use. So we cut them back to 4 in., shifted 

 them into 4s, and plunged them in a frame ten inches apart. They 

 came out in fine shape and have more than paid for themselves. 



PHILADELPJIUS 



The forms of Philadelphus (also called Syringa or Mock Orange) 

 are among the best known and most widely used hardy shrubs; 

 we find them in every assortment on the average home ground. 



Philadelphus coronarius is the old favorite and becomes loaded 

 down with its garland-like masses of white, Jasmine-scented flowers 

 in June. P. Gordonianus flowers fully a month later and P. aureus 

 is the golden leaf variety, very effective for planting in groups. 



The florist who does landscape work or sells hardy stock should 

 have a few specimen plants for his customers to look at on his 

 own grounds, and should carry the usual 2- to 3-ft. stock plants in 

 Spring and Fall.
