There is a rapid cold hardening capacity found within certain insects that suggests not all insects can survive a long period of overwintering. Non-diapausing insects can sustain brief temperature shocks but often have a limit to what they can handle before the body can no longer produce enough cryoprotective components. The common fruit fly
[6] [7] If the temperature continues to decrease, the water that was drawn out of cells will also freeze, causing further cell shrinkage. [5] Excessive cell shrinkage is dangerous because as ice forms outside the cell, the possible shapes that can be assumed by the cells are increasingly limited, causing damaging deformation. [ 8 ]
Depending on the plant species, maximum freezing tolerance can be reached after only two weeks of exposure to low temperatures. [2] The ability to control intercellular ice formation during freezing is critical to the survival of freeze-tolerant plants. [ 3 ]
Most outdoor plants in the UK fall within the range H4, −10 to −5 °C (14 to 23 °F) (hardy in the average winter) to H5, −15 to −10 °C (5 to 14 °F) (hardy in a cold winter). Also, the average minimum temperature in the UK is much warmer than the average minimums in much of the northern US, while the average maximums in the northern ...

As a succulent plant, Kalanchoe daigremontiana can survive prolonged periods of drought with little or no water. During growth periods with higher temperatures and increased water supply, this species requires proper nutrition, without which leaves show deficiency symptoms such as crippled growth and pustule-like lesions.
