How do I draw a tree upside down in qtree?

So root at the bottom and leaves at the top.

Answer 1

Page two in the manual should solve your problem.

The grow=direction and grow'=direction options control the orientation of trees just as for standard TikZ trees. However, direction must be one of up, down, left, or right. The difference between grow and grow' is that grow places children counterclockwise with respect to their parent and grow' places them clockwise:

\begin{tikzpicture}[grow'=up]
            \Tree [.NP [.Adj upside-down ] [.N tree ] ]
\end{tikzpicture}
