OFFSETS. 



One of the methods adopted by Nature for the 

 continuity of species is the production of supple- 

 mentary plantlets at the sides of, and closely 

 attached to, the parent. This method ensures true 

 offspring, as it is a purely vegetative process and 

 quite independent of sexual reproduction, with its 

 subsequent possibility of seminal variation. Bulb- 

 ous plants form the most important group in which 

 increase is naturally by offshoots, and it is entirely 

 due to this that stocks of florists' varieties of 

 Hyacinths, Tulips, Narcissi, etc., are kept true for 

 practically any number of years with the utmost 

 ease, and without that continual " rogueing " and 

 selecting that is necessary to maintain varieties of 

 florists' flowers raised only from seed. During the 

 period of rest, offsets sufficiently large to start on 

 their own account should be parted from the 

 parent, and grown by themselves until they reach 

 a flowering size. 



Offset production is assisted when seed produc- 

 tion is prevented. Highly bred and highly fed 

 subjects, like the present race of Amaryllises or 

 Hippeastrums, do not make offsets freely, owing 

 to the great tax which the large inflorescence 

 makes upon their energies, even provided no seed
