The two most widely used publications for determining where a plant may survive are the USDA 'Plant Hardiness Zone Map' and the Western Garden Book. The USDA Plant Hardiness Zone for Anaheim is 9b-10b.
Here is a link in order to determine and compare the zone you live in:
http://www.usna.usda.gov/Hardzone/ushzmap.html
The Western Garden Book has its own zone structure and specifies in each plant's description which zones are suited to it. Please keep in mind that many of the plants grown at Disneyland can take much harsher conditions than those found in Anaheim. For example, Erythrina crista-galli, although frozen to its roots, has been known to grow as far north as Maryland. Ensete bananas, Washingtonia palms, and Phoenix canariensis can grow in warmer parts of Oregon.
To assist you in determining the suitability of your climate, we have provided a table of monthly and annual totals for various factors in the Anaheim area. Compare them to what you know about your area.
