from the roof, and about two or three feet apart, 
answer admirably. Or the wires may be strung 
vertically along the back wall. When growing 
the plants as pot specimens, special forms of 
wire frame are often used. For such vines as 
allamanda, stephanotis, etc., it will suffice to 
stick five or six stakes upright against the rim 
of the pot, spreading them out at the top or 
bringing them together in the centre and tying; 
or, as before, the wires may be left standing erect. 
A balloon frame is very popular. This is

wires extending vertically from the sides of the 
pot. The smallest ring is put at the top, the
