(Heath plants are adapted to dry-soil conditions, and for this reason some of them are common to other habitats, such as dry pastures, which may formerly have been heaths, commons, etc. Heath plants are also adapted to physiologically dry conditions, and may grow on moors, which are in turn akin to bogs. Therefore the plants included in this section may under certain conditions be found elsewhere, and vice versa. As a whole they form a well-marked group or type of formation, characterized by a dry sandy soil, with acid humus.)

Vespa rufa is a frequent visitor also.
The berry is blue or bluish-green or black, and is eaten by birds, and the seeds are thus dispersed.
