I just stumbled across this web site.
It perhaps has a tropical bias, but quite a few of the genera or species are grown in mediterranean climates.

For instance: Jacaranda mimosifolia:
http://www.worldagroforestrycentre.org/sea/Products/AFDbases/af/asp/SpeciesInfo.asp?SpID=1011

You'll see it covers best propagation methods (including seed pre-treatments), pests and diseases, cultivational preferences, warnings, etc.

Worth filing away for future reference...
...if you can remember where!
