Plants by adaptation

Heliophytes or sunstroke plants are adapted to a habitat with a very intensive insolation by their structure and metabolism. Examples are mullein, ling, thyme and soft velcro, white clover, and most roses. They are common in open terrain, rocks, meadows, as well as at the mountain pastures and grasslands and other long sunny exposures.
