The red colour often perceived on Aloe microstigma leaves indicates the plant’s reaction to stress factors of heat, drought and sometimes more. This phenomenon is seasonally or otherwise reduced by moisture, moderate temperatures and other conditions conducive to favourable growth, flowering and seed production.

The taller outside leaves curve inwards in extreme heat, providing shade to the younger inner growth, thereby serving to reduce the plant’s temperature. When life is easier, the leaves may again open into the characteristic S-curve of the flourishing days, when more sunlight is absorbed for boosting photosynthesis and consequently the available nourishment.

Healthy plants in habitat normally have comfortable and stressed phases, changing appearance in accordance with living conditions. Plants lack the human propensity for continually searching greater comfort after survival requirements have been met. Animals are similar to plants in this, making humanity the only species threatening the survival of most, by over-management of the environment to suit its every want (Van Wyk and Smith, 2003; Wikipedia).
