text_A: The weather in Southern California is such that the temperature rarely rises above 54 degrees in winter, thus, heat and sun-loving crops like pistachios, kiwifruit, avocadoes, strawberries, and tomatoes don't grow in the region during winter, the last often dried in the sun and a feature of salads and sandwiches only grow well in summer there.

YES.
