In these forests, winter is a time of dormancy for plants, [8] when broadleaf deciduous trees conserve energy and prevent water loss, and many animal species hibernate or migrate. [1] Preceding winter is fruit-bearing autumn, a time when leaves change color to various shades of red, yellow, and orange as chlorophyll breakdown gives rise to ...
East Los Angeles, the Gateway Cities, and parts of the San Gabriel Valley average the warmest winter high temps (72 °F, 22 °C) in all of the western U.S., and Santa Monica averages the warmest winter lows (52 °F, 11 °C) in all of the western U.S. Palm Springs, a city in the Coachella Valley, averages high/low/mean temperatures of 75 °F/50 ...
Plants can be said to migrate, as seed dispersal enables plants to grow in new areas, under environmental constraints such as temperature and rainfall. When those constraints change, the border of a plant species's distribution may move, so the plant may be said to migrate, as for example in forest migration .
Those that do better in the warmer weather will, over successive populations, follow the warmer weather south. Essentially, seeds spread and the population gradually shits to wherever the majority ...

Possibly the most obvious change plants experience in the winter is a drop in temperature. Most houseplants, Nemali said, prefer to live between 68 degrees and 75 degrees Fahrenheit.
Plants that originated in the tropics, like tomato or maize, don't go through cold hardening and are unable to survive freezing temperatures. [3] The plant starts the adaptation by exposure to cold yet still not freezing temperatures. The process can be divided into three steps.
Temperatures stayed below freezing for up to eight hours at some valley locations, resulting in significant damage to plants and commercial agriculture. [23] In the winter months, high-pressure systems over the deserts often bring Santa Ana winds, resulting in dry, and dusty days. On rare occasion, temperatures can reach into the 85 to 95 °F ...
