I'd be grateful for suggestions for a suitable canopy tree to fulfill the
following criteria in my house in south of France:

1. It will be near a swimming pool, so should not drop too much detritus
(leaves not ok - a few flower petals or needles is ok). I'd like it to
provide attractive dappled shade.

2. It must be capable of living in south of France climate. Water will not
be an issue as I have irrigation - but it gets hot in summer. The mistral
winds can hit 40mph sometimes so needs to be fairly wind resistant.

3. I want to block out my neighbours view of my garden (no worries from
their point of view - very friendly about it!) and so the ideal canoby shape
will be about 8ft (2.5m) tall, 15ft (4.5m) wide, 3ft high. But if it gets
bigger, not too much of a problem.

Grateful for ideas.
