The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
Now the plant can absorb more light. When the sun dries the plants, they turn white. Thanks to this special survival trick, plants without roots can absorb fog droplets as well as rainwater and thus cover their water needs. [18] More than one-third of a tropical forest's vascular plants are epiphytes which species of Tillandsia are part of.
Oenothera will bloom in the evening and appear to be white or yellow, and by morning they fade to pink or orange. [10] Floral color change can also be a result of an increase or decrease in pH. Hydrangea is a model genus for this particular chemical change in flowers.

A study published in 2014 found that plant matter – leaf litter and trunks of dead trees – in the Red Forest area decays at a far slower rate than is typical for forest detritus. The researchers found that microorganisms responsible for decomposing forest litter do not act on such matter within the contaminated zone at nearly the rate seen ...
