410 FRITZ BAHR'S COMMERCIAL FLORICULTURE 



Seed of Impatiens is now offered and in three months after 

 sowing you can have bushy plants in full bloom. But of course 

 they come in all colors and shades, and a better way, if you have a 

 good sort on hand, is to propagate through cuttings. 



IPOM(EA GRANDIFLORA (MOONVINE) 



The only trouble with these grand climbers in our northern 

 climates is that while they grow finely and cover a lot of space, 

 they never flower, or do so so late that it hardly pays. This is due 

 to planting out too small plants or such as have been grown from 

 late-sown seed. Moonvines, with their large flowers often measur- 

 ing over six inches in diameter, are among the showiest of aU climbers, 

 but should be heavy 4- or 5-in. pot plants by the time you plant 

 them out in May. Such stock will start to flower in July and keep 

 it up, the plants becoming each evening a mass of color. The 

 flowers, like those of most Ipomcsas, remain open a good part of 

 the forenoon. In order to get large plants by Spring, root cuttings 

 of the outdoor plants in early Fall and keep them going aU Winter 

 inside. In early Spring they will start to move rapidly and should 

 have several shifts. 



If your . patrons ask for Moonvines you will only disappoint 

 them by selUng small stock, that is, in any section of the country 

 where the real Summer season is a short one.

IRIS 



Among the desirable perennials, those best known and able to 

 get along with the least attention, the German and Japanese Iris 

 almost head the list. Not that they can take the place of Peonies, 

 Delphiniums or Phloxes, but they can stand more abuse. Among 

 the German Iris, in particular, some grand new sorts have been 

 brought out of late years. They are money makers for every florist 

 who handles hardy stock because, once established, they can be 

 increased in great numbers and they will thrive in almost any soil — 

 not only in a deep, rich mixture and where the roots are moist at 

 all times, but on high ground too poor for other plants. 



Iris Germanica, or German Iris 



As stated above, some grand sorts have been of late years 

 brought out in this group. Of these Iris pallida dalmatica is one of 

 the very finest, growing fully four feet in height with a mass of 

 large lavender flowers. These flowers have only to be seen by any 

 of your patrons who are fond of the hardy border to bring you an 

 order. Other good sorts are Sherwin Wright, a pure golden yellow
