310 HARDY PERENNIALS. 



more than ordinary damage. Young specimens, 6in., 9in., or not 

 more than 12in. high, should be preferred, and of these sizes the 

 least will prove the safest. Yuccas are readily propagated at 

 the proper season ; and in specifying the season it is needful to 

 point out that of offsets, from which young stock is soonest 

 obtained, there are two kinds. Some spring from immediately 

 below the earth, and may more properly be termed suckers ; the 

 others grow on the visible part of the stem or caudex, often close 

 to the oldest leaves ; these should be cut off with a sharp knife, 

 in early summer, and if they have a little of the parent bark 

 attached to them all the better. If they are planted in a shady 

 place, in sweet sandy loam, they will make good roots before 

 winter, and may be allowed to make the following summer's 

 growth in the same position. In the succeeding autumn it will 

 be a good plan to put them in their permanent places. The 

 suckers will be found to have more or less root ; they should 

 be taken in spring from the parent specimen, the roots should be 

 carefully preserved, and the pushing parts planted just level 

 with the surface.
