Another squash question.

[stuffed]

What sort of size do the bush varieties grow to?
Do they need any support?
I've got some Jaspee de Vendee which are apparently a bush type.

Stuffed,
Our bush courgette plants have never needed any support.  They grow to about 3 feet across, but that is mainly made up of large leaves on thick hollow stems. 
The flowers/fruits tend to emerge from close to the centre of the plant, and the plant itself just gets kind of..... bushy. :D
You can always lop off a few leaves if it spreads out too far.
