The plants especially to be mentioned in this cate- 

 gory are Swiss chard, beet tops, spinach, kale, endive, 

 and mustard. Many other plants find occasional or 

 local favor. See Greens. 



The only general cultural directions which can be 

 given for salad plants are that blanching is often desir- 

 able and a quicli unchecked growth is always a requisite. 

 An abundance of rapiilly avaihil.li- fertilizer and plenty 

 of water are theref.ir. t.. L. insisted on. A warm, 

 light soil, in the bi-t ni.cliani, a| condition, is nec- 

 essary for the same rias..i,s. y. A. WaL'GH.

Besides the salad plants proper, many vegetables are 

 used in a cooked or raw condition for salads. Such are 

 cabbage, cauliflower, brussels sprouts, potatoes, lima 

 beans, beets, Jerusalem artichoke, etc. With salad 

 plants may also be included pot-herbs, or "greens."

has been suggested that the britil 



of some species, notably t-lje Bla 



is an adaptation to facilitate naturally the distribution 

 of the species. Certain it is that twigs broken from 

 the tree by the wind are carried down streams and, be- 

 coming anchored in the muddy banks, grow there. It is 

 one of the most aggressive trees in occupying such 

 places.
