CHAPTER I 



Propagation 



Fern propagation is one of the most interesting branches 

 of Horticulture. There are so many methods by which 

 stock may be renewed, or increased. And it is interest- 

 ing to note that it is those species which fail to reproduce 

 from spores, which are most readily propagated by some 

 other means. Take Adiantum captflus-veneris var. im- 

 bricatum : this produces tiny little bulbils round the 

 margins of the fronds ; and these, when laid on suitable 

 soil, will soon form young plants. It may be added here 

 that in some instances it has reverted to the normal form, 

 or more like A. c. p. magnificum, and spores have been 

 found, but the best type is barren of spores. The dense 

 growing Scolopendrium vulgare, var. Kelivayi, on well 

 matured fronds, develops tiny bulbils which may be taken 

 off and treated as small seedlings. Another variety of 

 Scolopendrium produces bulbils on the surface of its fronds. 

 Many of the Aspleniums are very prolific in surface bulbils. 

 Other Ferns produce root bulbils, others have spreading 

 rhizomes. These are all dealt with in their proper order. 

 In almost all instances where spores can be obtained, it 

 will be found to be the best method of propagation. 

 The collecting of the spores is of great importance. All 

 choice sorts should be taken from plants isolated as far 

 as possible from the free growing species, or what may 

 be termed Fern weeds. The worst weeds are Nephrodium 

 molle Gymnogramma Martensi and the free growing 

 Pterises.
