BEHAVIOUR OF CLIMBING PLANTS POO 
or tree the branches become bushy, and the leaves lose 
their five pots and grow simple without any notches 
in them. Then the ivy produces its green flowers in 
almost globular heads, which are followed by green or 
purple berries. Some people think that the trailing 
ivy and the bushy ivy are two different kinds, but 
they are the same plant in various stages of its life. 
Some plants climb by leaning on others for support. 
As they grow upward, being too weak to support them- 
selves alone, they fall against other plants and grow 
over and between their branches. Such plants are 
sometimes called scramblers, because they scramble over 
others.
