GREENHOUSE AND HOTHOUSE FLOWERS 185 



autumn blooming, and in the latter in summer for flowering the 

 following spring. Several colours are obtainable. They succeed 

 with the normal soil and treatment. The East Lothian is another 

 fine strain of pot Stocks. 



Streptocarpus. This is an example of an old plant taken in 

 hand by hybridisers and improved so much as to become practi- 

 cally a new flower. It is a most charming plant, bearing abund- 

 ance of attractive, tubular flowers, which embrace many pleasing 

 shades of lavender, grey, blue, lilac, and mauve. In the newest 

 forms the size of the flowers has grown so much that the Strepto- 

 carpus promises to rival the Gloxinia in a few years' time. The 

 foliage is handsome too. It may be grown in a greenhouse, but it 

 is often given a warmer structure in order to get earlier bloom. 

 It comes from seed readily enough, and may have the normal treat- 

 ment. Seed may be sown in spring for giving strong flowering 

 plants the following year. The plants may also be propagated by 

 leaf cuttings, in the same way as some of the Begonias. 



Torenia. The lovely little Torenias are not half enough grown 

 by owners of hothouses, considering that they are easily raised 

 from seed. The beautiful violet species Fournieri, and the equally 

 pretty yellow flava, or Bailloni as it is often called by seedsmen, 

 are real gems, bearing their exquisite flowers in profusion. The 

 latter species is often grown in baskets, to which purpose its 

 pendulous habit lends itself. The seeds may be sown in spring 

 and given ordinary treatment, while the normal soil will do 

 quite well, although some peat may be added with advantage if 

 available. 



Tulips. See Bulb section. 



The foregoing notes do not include all the plants worth grow- 

 ing in glass-houses to do that would be to greatly exceed the 

 space available but they comprise the most important, and will 

 serve to show that there is abundance of material at the service 

 of cultivators.
