Palm trees are one of the many trees that grow well in Davis. Popular types include the European originating Mediterranean Fan Palm, the somewhat more local California Fan Palm from Southern California and the Mexican Fan Palm. They can be found in the Arboretum's desert collection.
A notable pair of trees are located in front of In-N-Out Burger. They form the middle X of the "Big W" configuration from It's a Mad, Mad, Mad, Mad World. The entire store is heavily decorated in palm trees.
If you see a tiny "bush palm tree", it is likely a cycad like the sago palm.
