LIST OF PLANTS 149 
the Tritonias, but still retain the old name in gardens. 
Offsets are freely produced on stolons from the old 
roots, and these are easily detached and grown on to a 
flowering size. Seedlings raised in spring grow large 
enough to blossom in one or two years. — 
Mutperry (Morus nigra).—The common way of 
propagating these trees is by layering young branches 
in autumn; also by cuttings in autumn, selecting for the 
purpose shoots from the tops of old trees, as they are 
credited with coming into bearing sooner. From 6 inches 
to g inches is a suitable length, and the base should 
consist of a portion of two-year-old wood and all the 
buds except two at the top removed. These are either 
planted half their length deep in a sheltered, shady 
border outside or plunged in bottom heat in a frame 
until rooted. Even long branches will root and grow if 
planted a foot deep and secured from moving by tying 
to a stake. | 
Musa.—Most of the edible-fruited sorts are seedless, 
but they are readily increased by suckers thrown up 
from the root by old plants. M. Ensete, so effective in 
sub-tropical gardening, is raised from imported seed 
sown in heat in February. 
Musnroom.—These are raised artificially in cool, dark 
sheds, cellars, and Mushroom houses by inserting pieces 
of prepared spawn containing the mycelium in beds of 
manure that has been partly fermented to dispel its 
rankness by turning it over at intervals. The material 
is made firm, and when the heat has dropped to about 
85 degrees the spawn, broken into lumps the size of an 
egg, is planted 2 inches deep and the whole covered 
with an inch or two of loam, this being beaten firm and 
level with the back of a spade.
