328 FRITZ BAHR'S COMMERCIAL FLORICULTURE 



Even if you haven't any use for the flowers themselves, if you have 

 the plants in a place where they can be seen, you will have a good 

 ad that wiU lead to your taking orders for plants for the following 

 Spring's delivery. 



This Clematis is one of the best hardy climbers you can recom- 

 mend. C. Jackmanii and C. Henryi often cause disappointment by 

 dying after having made five or six feet of growth, but C. panieulata 

 hardly ever causes trouble or fails to do well even when planted in 

 soil not of the best. 



This Clematis is easily grown from seed but it won't pay the 

 florist using only a few plants each year to raise it. Rather let your 

 nurseryman furnish what plants you need. Among the shrubby 

 forms of Clematis are severaj good ones; C. ereda is especially good, 

 about three feet in height and covered with white flowers in June. 



COB^A SCANDENS 



Easily the best of all Summer climbers; a fast grower, almost free from 

 disease or insect pests, and good for sun or shade. Starting out with 

 heavy plants, the purchaser doesn't have to wait until October before 

 the vines cover the front porch trellis. 



If you have among your customers some who are willing to pay 

 the price, you can afford to sow seeds of Cobaea about the first of 

 February, pot the seedhngs into 23^-in. pots, then pinch them 

 several times, shift them into 4s and later on into 6s and put a 6-ft. 

 Bamboo stake in each pot. Keep on tying up the six or eight shoots 

 as they grow and by May the plants wiU be as high as the stakes. 

 If planted out, they will, by the end of July, have made another 

 six or eight feet of growth. 



For smaUer plants, sow a month later — ^and you may well have 

 another batch coming on from seed sown the end of March. The 

 seeds should always be put in edgewise; have the flat fiUed with 

 soil and press each seed into the surface no matter what else you 

 do. UsuaUy the two seed leaves will have a 2- or 3-in. stem; when 

 you pot the seedlings up, try to get them well down into the pots, 

 so the two leaves touch the surface of the soil. Then, when you 

 shift the next time, set the plants as deep as you can and never 

 neglect to tie the plants in good time. It is an awful job to tackle a 

 batch of plants which have been allowed to grow into each other for 

 several weeks or a month.
