292 FRITZ BAHR'S COMMERCIAL FLORICULTURE 



Fig. 117. — Calendulas in Variety. The 

 variety most used by florists for indoor cul- 

 ture is "Orange King" or "Orange Prince." 

 It is an ideal coldhouse crop and a money 

 maker for the retail florist who doesn't 

 have to send his flowers to the wholesale 

 market in competition with others 



in bloom with their endless 

 different shadings and their 

 odd flower markings will 

 attract more attention than 

 almost anything else you have 

 in the show house. It is, 

 therefore, bound to help sell 

 other things. 



Calceolarias are easily 

 grown from seed, which should 

 be sown during July. The 

 cooler and more airy the house 

 the seedUngs are in, the better; 

 let them have a Uttle shade, 

 too. You can grow them 

 nicely on the same bench with 

 your Primulas and Cinerarias 

 while small. During Summer 

 they make but little headway, 

 but with cool nights they 

 soon make up. Let them have 

 a light, porous soil, especially 

 when small, and when you 

 shift them into 4s (which is 

 usually about the end of 

 November) loam with one-fifth 

 well-rotted cow manure makes 



a good mixture. Keep them in a cool house, say 45 deg. over 

 Winter and keep them shifted, for it is after October that they 

 make their main growth. 



What causes more failures, perhaps, than anything else, is letting 

 green fly get a foothold among the leaves and at the center of the 

 plants. This pest is so fond of Calceolarias that if there are any 

 plants in the house, they surely will be full of green fly before any 

 other plant shows even a sign of them. This means that you have 

 to be continuously on the lookout; a good practice is to not 

 only spray and fumigate regularly, but also place some tobacco 

 stems between the little pots or around the flats or below them. 

 If you keep them clean, cool and use a little care in watering, you 

 should be able to grow them in almost any kind of house. 



CALENDULAS 



These plants well deserve to be called money makers for the florist. 



A good many dollars have found their way into the pockets of 



the florist since he started to grow Calendulas under glass and display 



them in Midwinter at a time when their bright, orange-colored flowers
