There are no serious insects or diseases. 



TURNIP -ROOTED CHERVIL 



This is a small -rooted plant, something like carrot, 

 except that the roots are gray or nearly black and of 

 different flavor. The seed does not germinate well if 

 kept dry over winter. It is, therefore, sown in August 

 or September, although it usually does not germinate 

 until spring. Otherwise the culture is like that for car- 

 rot. The root is used as carrot is. It matures in early 

 summer, but improves by remaining in the ground. It 

 is little known in America. 



Tuberous or Turnip -rooted Chervil is Choerophyllum 

 hulbosimi, a native of southern Europe, and one of the 

 Umbelliferae. Salad Chervil is a different plant (see 

 Chap. 14).
